  /**
   * An extension of the "same-value" algorithm as [described for use by ES6 Map
   * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
   *
   * NaN is considered the same as NaN, however -0 and 0 are considered the same
   * value, which is different from the algorithm described by
   * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
   *
   * This is extended further to allow Objects to describe the values they
   * represent, by way of `valueOf` or `equals` (and `hashCode`).
   *
   * Note: because of this extension, the key equality of Immutable.Map and the
   * value equality of Immutable.Set will differ from ES6 Map and Set.
   *
   * ### Defining custom values
   *
   * The easiest way to describe the value an object represents is by implementing
   * `valueOf`. For example, `Date` represents a value by returning a unix
   * timestamp for `valueOf`:
   *
   *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
   *     var date2 = new Date(1234567890000);
   *     date1.valueOf(); // 1234567890000
   *     assert( date1 !== date2 );
   *     assert( Immutable.is( date1, date2 ) );
   *
   * Note: overriding `valueOf` may have other implications if you use this object
   * where JavaScript expects a primitive, such as implicit string coercion.
   *
   * For more complex types, especially collections, implementing `valueOf` may
   * not be performant. An alternative is to implement `equals` and `hashCode`.
   *
   * `equals` takes another object, presumably of similar type, and returns true
   * if the it is equal. Equality is symmetrical, so the same result should be
   * returned if this and the argument are flipped.
   *
   *     assert( a.equals(b) === b.equals(a) );
   *
   * `hashCode` returns a 32bit integer number representing the object which will
   * be used to determine how to store the value object in a Map or Set. You must
   * provide both or neither methods, one must not exist without the other.
   *
   * Also, an important relationship between these methods must be upheld: if two
   * values are equal, they *must* return the same hashCode. If the values are not
   * equal, they might have the same hashCode; this is called a hash collision,
   * and while undesirable for performance reasons, it is acceptable.
   *
   *     if (a.equals(b)) {
   *       assert( a.hashCode() === b.hashCode() );
   *     }
   *
   * All Immutable collections implement `equals` and `hashCode`.

   * ### Available metadata attributes
   *
   * All binaries have the meta attributes `content_length` and `content_type`, in addition, PDFs
   * and images have attributes specific to their type.
   *
   * If not specified otherwise, the attributes contain `string` values.
   *
   * - `content_length` (Number value) - Size in bytes of the given file.
   * - `content_type` - MIME-type of the given file.
   *
   * ### Available metadata attributes for PDFs
   *
   * - `text` - Text content of the PDF document.
   *
   * ### Available metadata attributes for Images
   *
   * The metadata attributes starting with `iptc_` or `exif_` are extracted from the image itself
   * and therefore may not be available for every image. `iptc` and `exif` are both standardized
   * formats supported by a wide array of software and hardware, like cameras and phones.
   *
   * - `width` (Number value) - Width in pixels.
   * - `height` (Number value) - Height in pixels.
   * - `exif_copyright` - Copyright of the image.
   * - `exif_date_time` - The date at which the image was produced.
   *
   * - `iptc_keywords` (Array with Strings value) - A list of keywords associated with the image.
   * - `iptc_headline` - The headline of the image.
   * - `iptc_copyright` - Copyright of the image.
   * - `iptc_byline` - The name of the image creator.
   * - `iptc_credit` - Contains the persons or companies that should be credited.
   * - `iptc_source` - The original copyright holder.
   * - `iptc_profile` - The color profile of the image.
   * - `iptc_city` - The city in which the image was produced.
   * - `iptc_state` - The state in which the image was produced.
   * - `iptc_country_name` - The country in which the image was produced.
   * - `iptc_country_code` - The code of the country in which the image was produced.
   *
   * ### Searching for metadata
   *
   * Metadata is taken into account when searching. See the
   * {@link ObjSearchIterable ObjSearchIterable} for details.
   *
   * @example <caption>Search for all JPEGs</caption>
   *   Image.where('blob:content_type', 'equals', 'image/jpeg')
   *
   * @example <caption>Search for wide images</caption>
   *   Image.where('blob:width', 'is_greater_than', 1024)

     * Allows iterating over the results of searches for CMS objects to retrieve instances of

     * objects as are actually needed.
     *
     * ## Available fields and their values
     *
     * - `'*'` - Searches all fields
     * - `'_id'` - Id of an {@link Obj}. This is a `string` field.
     * - `'_path'` - Path of an {@link Obj}. This is a `string` field.
     * - `'_obj_class'` - Object class of an {@link Obj}. This is a `string` field.
     * - `'_permalink'` - Permalink of an {@link Obj}. This is a `string` field.
     * - `'_last_changed'` - Date of last change to an {@link Obj}.
     * - every `custom_attribute` Custom attribute of an {@link Obj}. Note that
     *    depending on the attribute type (e.g. an `html` field), some operators cannot be
     *    applied.
     *
     * ## Available operators
     *
     * **`contains` and `contains_prefix`**
     *
     * These operators are intended for full text search of natural language texts.
     * They are applicable to `string`, `stringlist`, `enum`, `multienum` and `html` fields.
     *
     * For `contains` and `contains_prefix`, the examples are based on the following field value:
     * "Behind every cloud is another cloud."
     *
     * **`contains`**
     *
     * Searches for one or more whole words. Each word needs to be present.
     * Example subquery values:
     *
     * ✔ "behind cloud" (case insensitive)
     *
     * ✘ "behi clo" (not whole words)
     *
     * ✘ "behind everything" (second word does not match)
     *
     * **`contains_prefix`**
     *
     * Searches for a word prefix.
     * Example subquery values:
     *
     * ✔ "Clou" (case insensitive)
     *
     * ✔ "Every" (case insensitive)
     *
     * **`equals`**
     *
     * The `equals` operator is intended for programmatic comparisons of string and date values.
     *
     * The operator has some limits with regard to string length. String values are only guaranteed
     * to be considered if they are at most 1000 characters in length.
     * String values of more than 1000 characters may be ignored by these operators.
     *
     * For `equals`, the examples are based on the following field value:
     * "Some content."
     *
     * The `field` value needs to be identical to the `value` of this subquery.
     *
     * Applicable to `string`, `stringlist`, `enum`, `multienum` and `date` fields.
     * Example subquery values:
     *
     * ✔ "Some content." (exact value)
     *
     * ✘ "Some" (not exact value)
     *
     * **`starts_with`**
     *
     * The `starts_with` is intended for programmatic comparisons of string values.
     *
     * The `starts_with` operator has a precision limit:
     * Only prefixes of up to 20 characters are guaranteed to be matched.
     * If you supply a prefix of more than 20 characters, the additional characters may be ignored.
     *
     * When combined with the system attribute `_path`, the operator `starts_with` has some special
     * functionality:
     * There is not precision limit, i.e. a prefix of arbitrary length may be used to match on
     * `_path`.
     * Also, prefix matching on `_path` automatically matches entire path components,
     * i.e. the prefix matching is delimited by slashes (the character `'/'`).
     *
     * For `starts_with`, the examples are based on the following field value:
     * "Some content."
     *
     * The `field` value needs to start exactly with the `value` of this subquery.
     *
     * Applicable to `string`, `stringlist`, `enum` and `multienum` fields.
     * Example subquery values:
     *
     * ✔ "Som" (prefix of the value)
     *
     * ✘ "som" (incorrect case of prefix)
     *
     * ✘ "content" (not prefix of the whole value)
     *
     * **`is_less_than` and `is_greater_than`**
     *
     * These operators are intended for comparing `date` or numerical values. They can also be
     * applied to numerical metadata, for example the width of an image.
     * It only considers attributes of {@link Obj Objs} and **not** of
     * {@link Widget Widgets}. Therefore, Widget attributes are not searchable
     * using the `is_less_than` and `is_greater_than` operators.
     *
     * For `is_less_than` and `is_greater_than`, the examples are based on the following date value:
     * `new Date(2000, 0, 1, 0, 0, 0)`
     *
     * **`is_less_than`**
     *
     * Matches if the field value is less than the subquery date value.
     * Example subquery values:
     *
     * ✔ `new Date(1999, 11, 31, 23, 59, 59)` (is less than)
     *
     * ✘ `new Date(2000, 0, 1, 0, 0, 0)` (equal, not less than)
     *
     * **`is_greater_than`**
     *
     * Matches if the field value is greater than the subquery string value.
     * Example subquery values:
     *
     * ✔ `new Date(2000, 0, 1, 0, 0, 1)` (is greater than)
     *
     * ✘ `new Date(2000, 0, 1, 0, 0, 0)` (equal, not greater than)
     *
     * **`links_to`**
     *
     * The `links_to` operator searches for CMS objects containing one or more attributes linking to
     * specific CMS objects. So the operator returns the CMS objects in which at least one `html`,
     * `link`, `linklist`, `reference` or `referencelist` attribute links to specific CMS objects.
     *
     * The operator can only be applied to all attributes, so the `"*"` wildcard _must_ be specified
     * for the attributes to search. If you want to search specific `reference` or `referencelist`
     * attributes, please use the `refers_to` operator.
     *
     * Using `null` instead of an instance of {@link Obj} results in an error.
     *
     * Note that, in contrast to the `refers_to` operator, the `links_to` operator searches the
     * attributes directly part of the CMS objects _as_ _well_ _as_ the attributes contained in
     * widgets.
     *
     * Example subquery values:
     *
     * ✔ `myObj` (an instance of {@link Obj})
     *
     * ✔ `[myObj1, myObj2]` (an `Array` of instances of {@link Obj})
     *
     * ✘ `null` (not an instance of {@link Obj})
     *
     * ✘ "someString" (not an instance of {@link Obj})
     *
     * **`refers_to`**
     *
     * The `refers_to` operator searches for CMS objects in which at least one of the specified
     * `reference` or `referencelist` attributes refers to specific CMS objects.
     *
     * Using the `"*"` wildcard for the attributes to search causes all `reference` and
     * `referencelist` attributes of the searched CMS objects to be taken into account.
     *
     * Using `null` instead of {@link Obj Objs} searches for all CMS objects in which
     * none of the specified attributes refer to a CMS object.
     *
     * Note that, in contrast to the `links_to` operator, the `refers_to` operator only searches
     * attributes _directly_ _part_ _of_ _the_ _CMS_ _objects_. Currently, attributes contained in
     * widgets are _not_ searched.
     *
     * Example subquery values:
     *
     * ✔ `myObj` (an instance of {@link Obj})
     *
     * ✔ `[myObj1, myObj2]` (an `Array` of instances of {@link Obj})
     *
     * ✔ `null`
     *
     * ✘ "someString" (not an instance of {@link Obj})
     *
     * **Matching `multienum` and `stringlist`**
     *
     * Attributes of type `multienum` and `stringlist` contain an array of strings. Each of these
     * strings is searched individually.
     *
     * A search query matches a `multienum` or `stringlist`, if at least one string in the list
     * matches. Example: A query using the operator `:equals` and the value `"Eggs"` matches an
     * Obj containing `["Spam","Eggs"]` in a `stringlist` or `multienum` attribute.
     *
     * ## Limits
     *
     * The number of chainable subqueries is limited. The limit depends on the number of values,
     * fields, and boost parameters requested, as well as the number of words in a free text
     * search.
