+         * - hitsPerPage: (integer) Pagination parameter used to select the number of hits per page. Defaults to 20.
+         * - attributesToRetrieve: a string that contains the list of object attributes you want to retrieve (let you minimize the answer size).
+         *   Attributes are separated with a comma (for example "name,address").

+         * - attributesToHighlight: a string that contains the list of attributes you want to highlight according to the query.
+         *   Attributes are separated by a comma. You can also use a string array encoding (for example ["name","address"]).
+         *   If an attribute has no match for the query, the raw value is returned. By default all indexed text attributes are highlighted.
+         *   You can use `*` if you want to highlight all textual attributes. Numerical attributes are not highlighted.
+         *   A matchLevel is returned for each highlighted attribute and can contain:
+         *      - full: if all the query terms were found in the attribute,
+         *      - partial: if only some of the query terms were found,
+         *      - none: if none of the query terms were found.
+         * - attributesToSnippet: a string that contains the list of attributes to snippet alongside the number of words to return (syntax is `attributeName:nbWords`).
+         *    Attributes are separated by a comma (Example: attributesToSnippet=name:10,content:10).
+         *    You can also use a string array encoding (Example: attributesToSnippet: ["name:10","content:10"]). By default no snippet is computed.
+         * - minWordSizefor1Typo: the minimum number of characters in a query word to accept one typo in this word. Defaults to 3.
+         * - minWordSizefor2Typos: the minimum number of characters in a query word to accept two typos in this word. Defaults to 7.
+         * - getRankingInfo: if set to 1, the result hits will contain ranking information in _rankingInfo attribute.
+         * - aroundLatLng: search for entries around a given latitude/longitude (specified as two floats separated by a comma).
+         *   For example aroundLatLng=47.316669,5.016670).
+         *   You can specify the maximum distance in meters with the aroundRadius parameter (in meters) and the precision for ranking with aroundPrecision
+         *   (for example if you set aroundPrecision=100, two objects that are distant of less than 100m will be considered as identical for "geo" ranking parameter).
+         *   At indexing, you should specify geoloc of an object with the _geoloc attribute (in the form {"_geoloc":{"lat":48.853409, "lng":2.348800}})
+         * - insideBoundingBox: search entries inside a given area defined by the two extreme points of a rectangle (defined by 4 floats: p1Lat,p1Lng,p2Lat,p2Lng).
+         *   For example insideBoundingBox=47.3165,4.9665,47.3424,5.0201).
+         *   At indexing, you should specify geoloc of an object with the _geoloc attribute (in the form {"_geoloc":{"lat":48.853409, "lng":2.348800}})
+         * - numericFilters: a string that contains the list of numeric filters you want to apply separated by a comma.
+         *   The syntax of one filter is `attributeName` followed by `operand` followed by `value`. Supported operands are `<`, `<=`, `=`, `>` and `>=`.
+         *   You can have multiple conditions on one attribute like for example numericFilters=price>100,price<1000.
+         *   You can also use a string array encoding (for example numericFilters: ["price>100","price<1000"]).
+         * - tagFilters: filter the query by a set of tags. You can AND tags by separating them by commas.
+         *   To OR tags, you must add parentheses. For example, tags=tag1,(tag2,tag3) means tag1 AND (tag2 OR tag3).
+         *   You can also use a string array encoding, for example tagFilters: ["tag1",["tag2","tag3"]] means tag1 AND (tag2 OR tag3).
+         *   At indexing, tags should be added in the _tags** attribute of objects (for example {"_tags":["tag1","tag2"]}).
+         * - facetFilters: filter the query by a list of facets.
+         *   Facets are separated by commas and each facet is encoded as `attributeName:value`.
+         *   For example: `facetFilters=category:Book,author:John%20Doe`.
+         *   You can also use a string array encoding (for example `["category:Book","author:John%20Doe"]`).
+         * - facets: List of object attributes that you want to use for faceting.
+         *   Attributes are separated with a comma (for example `"category,author"` ).
+         *   You can also use a JSON string array encoding (for example ["category","author"]).
+         *   Only attributes that have been added in **attributesForFaceting** index setting can be used in this parameter.
+         *   You can also use `*` to perform faceting on all attributes specified in **attributesForFaceting**.
+         * - queryType: select how the query words are interpreted, it can be one of the following value:
+         *    - prefixAll: all query words are interpreted as prefixes,
+         *    - prefixLast: only the last word is interpreted as a prefix (default behavior),
+         *    - prefixNone: no query word is interpreted as a prefix. This option is not recommended.
+         * - optionalWords: a string that contains the list of words that should be considered as optional when found in the query.
+         *   The list of words is comma separated.
+         * - distinct: If set to 1, enable the distinct feature (disabled by default) if the attributeForDistinct index setting is set.
+         *   This feature is similar to the SQL "distinct" keyword: when enabled in a query with the distinct=1 parameter,
+         *   all hits containing a duplicate value for the attributeForDistinct attribute are removed from results.
+         *   For example, if the chosen attribute is show_name and several hits have the same value for show_name, then only the best
+         *   one is kept and others are removed.

+         * - minWordSizefor2Typos: (integer) the minimum number of characters to accept two typos (default = 7).
+         * - hitsPerPage: (integer) the number of hits per page (default = 10).
+         * - attributesToRetrieve: (array of strings) default list of attributes to retrieve in objects.
+         *   If set to null, all attributes are retrieved.
+         * - attributesToHighlight: (array of strings) default list of attributes to highlight.
+         *   If set to null, all indexed attributes are highlighted.
+         * - attributesToSnippet**: (array of strings) default list of attributes to snippet alongside the number of words to return (syntax is attributeName:nbWords).
+         *   By default no snippet is computed. If set to null, no snippet is computed.
+         * - attributesToIndex: (array of strings) the list of fields you want to index.
+         *   If set to null, all textual and numerical attributes of your objects are indexed, but you should update it to get optimal results.
+         *   This parameter has two important uses:
+         *     - Limit the attributes to index: For example if you store a binary image in base64, you want to store it and be able to
+         *       retrieve it but you don't want to search in the base64 string.
+         *     - Control part of the ranking*: (see the ranking parameter for full explanation) Matches in attributes at the beginning of
+         *       the list will be considered more important than matches in attributes further down the list.
+         *       In one attribute, matching text at the beginning of the attribute will be considered more important than text after, you can disable
+         *       this behavior if you add your attribute inside `unordered(AttributeName)`, for example attributesToIndex: ["title", "unordered(text)"].
+         * - attributesForFaceting: (array of strings) The list of fields you want to use for faceting.
+         *   All strings in the attribute selected for faceting are extracted and added as a facet. If set to null, no attribute is used for faceting.
+         * - attributeForDistinct: (string) The attribute name used for the Distinct feature. This feature is similar to the SQL "distinct" keyword: when enabled
+         *   in query with the distinct=1 parameter, all hits containing a duplicate value for this attribute are removed from results.
+         *   For example, if the chosen attribute is show_name and several hits have the same value for show_name, then only the best one is kept and others are removed.
+         * - ranking: (array of strings) controls the way results are sorted.
+         *   We have six available criteria:
+         *    - typo: sort according to number of typos,
+         *    - geo: sort according to decreassing distance when performing a geo-location based search,
+         *    - proximity: sort according to the proximity of query words in hits,
+         *    - attribute: sort according to the order of attributes defined by attributesToIndex,
+         *    - exact:
+         *        - if the user query contains one word: sort objects having an attribute that is exactly the query word before others.
+         *          For example if you search for the "V" TV show, you want to find it with the "V" query and avoid to have all popular TV
+         *          show starting by the v letter before it.
+         *        - if the user query contains multiple words: sort according to the number of words that matched exactly (and not as a prefix).
+         *    - custom: sort according to a user defined formula set in **customRanking** attribute.
+         *   The standard order is ["typo", "geo", "proximity", "attribute", "exact", "custom"]
+         * - customRanking: (array of strings) lets you specify part of the ranking.
+         *   The syntax of this condition is an array of strings containing attributes prefixed by asc (ascending order) or desc (descending order) operator.
+         *   For example `"customRanking" => ["desc(population)", "asc(name)"]`
+         * - queryType: Select how the query words are interpreted, it can be one of the following value:
+         *   - prefixAll: all query words are interpreted as prefixes,
+         *   - prefixLast: only the last word is interpreted as a prefix (default behavior),
+         *   - prefixNone: no query word is interpreted as a prefix. This option is not recommended.
+         * - highlightPreTag: (string) Specify the string that is inserted before the highlighted parts in the query result (default to "<em>").
+         * - highlightPostTag: (string) Specify the string that is inserted after the highlighted parts in the query result (default to "</em>").
+         * - optionalWords: (array of strings) Specify a list of words that should be considered as optional when found in the query.
+         * @param callback (optional) the result callback with two arguments
+         *  success: boolean set to true if the request was successfull

+
+
+    This file creates a global JSON object containing two methods: stringify
+    and parse.
+
+        JSON.stringify(value, replacer, space)
+            value       any JavaScript value, usually an object or array.
+
+            replacer    an optional parameter that determines how object
+                        values are stringified for objects. It can be a
+                        function or an array of strings.
+
+            space       an optional parameter that specifies the indentation
+                        of nested structures. If it is omitted, the text will
+                        be packed without extra whitespace. If it is a number,
+                        it will specify the number of spaces to indent at each
+                        level. If it is a string (such as '\t' or '&nbsp;'),
+                        it contains the characters used to indent at each level.
+
+            This method produces a JSON text from a JavaScript value.
+
+            When an object value is found, if the object contains a toJSON
+            method, its toJSON method will be called and the result will be
+            stringified. A toJSON method does not serialize: it returns the
+            value represented by the name/value pair that should be serialized,
+            or undefined if nothing should be serialized. The toJSON method
+            will be passed the key associated with the value, and this will be
+            bound to the value
+
+            For example, this would serialize Dates as ISO strings.
+
+                Date.prototype.toJSON = function (key) {
+                    function f(n) {
+                        // Format integers to have at least two digits.
+                        return n < 10 ? '0' + n : n;
+                    }
+
+                    return this.getUTCFullYear()   + '-' +
+                         f(this.getUTCMonth() + 1) + '-' +
+                         f(this.getUTCDate())      + 'T' +
+                         f(this.getUTCHours())     + ':' +
+                         f(this.getUTCMinutes())   + ':' +
+                         f(this.getUTCSeconds())   + 'Z';
+                };
+
+            You can provide an optional replacer method. It will be passed the
+            key and value of each member, with this bound to the containing
+            object. The value that is returned from your method will be
+            serialized. If your method returns undefined, then the member will
+            be excluded from the serialization.
+
+            If the replacer parameter is an array of strings, then it will be
+            used to select the members to be serialized. It filters the results
+            such that only members with keys listed in the replacer array are
+            stringified.
+
+            Values that do not have JSON representations, such as undefined or
+            functions, will not be serialized. Such values in objects will be
+            dropped; in arrays they will be replaced with null. You can use
+            a replacer function to replace those with JSON values.
+            JSON.stringify(undefined) returns undefined.
+
+            The optional space parameter produces a stringification of the
+            value that is filled with line breaks and indentation to make it
+            easier to read.
+
+            If the space parameter is a non-empty string, then that string will
+            be used for indentation. If the space parameter is a number, then
+            the indentation will be that many spaces.
+
+            Example:
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}]);
+            // text is '["e",{"pluribus":"unum"}]'
+
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+            text = JSON.stringify([new Date()], function (key, value) {
+                return this[key] instanceof Date ?
+                    'Date(' + this[key] + ')' : value;
+            });
+            // text is '["Date(---current time---)"]'
+
+
+        JSON.parse(text, reviver)
+            This method parses a JSON text to produce an object or array.
+            It can throw a SyntaxError exception.
+
+            The optional reviver parameter is a function that can filter and
+            transform the results. It receives each of the keys and values,
+            and its return value is used instead of the original value.
+            If it returns what it received, then the structure is not modified.
+            If it returns undefined then the member is deleted.
+
+            Example:
+
+            // Parse the text. Values that look like ISO date strings will
+            // be converted to Date objects.
+
+            myData = JSON.parse(text, function (key, value) {
+                var a;
+                if (typeof value === 'string') {
+                    a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+                    if (a) {
+                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+                            +a[5], +a[6]));
+                    }
+                }
+                return value;
+            });
+
+            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+                var d;
+                if (typeof value === 'string' &&

+ *   it into the returned string, however, since our parser is more strict than a typical browser
+ *   parser, it's possible that some obscure input, which would be recognized as valid HTML by a
+ *   browser, won't make it through the sanitizer.
+ *   The whitelist is configured using the functions `aHrefSanitizationWhitelist` and
+ *   `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider `$compileProvider`}.
