         * Explicit chain sequences, which must be unwrapped with `_#value`, may be

         * fusion is subject to change.

         * Creates a throttled function that only invokes `func` at most once per

         * method to cancel delayed `func` invocations and a `flush` method to
         * immediately invoke them. Provide `options` to indicate whether `func`
         * should be invoked on the leading and/or trailing edge of the `wait`
         * timeout. The `func` is invoked with the last arguments provided to the
         * throttled function. Subsequent calls to the throttled function return the
         * result of the last `func` invocation.
         *
         * **Note:** If `leading` and `trailing` options are `true`, `func` is
         * invoked on the trailing edge of the timeout only if the throttled function
         * is invoked more than once during the `wait` timeout.
         *
         * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
         * until to the next tick, similar to `setTimeout` with a timeout of `0`.

    /**
     * Although lunr provides the ability to create queries using lunr.Query, it also provides a simple
     * query language which itself is parsed into an instance of lunr.Query.
     *
     * For programmatically building queries it is advised to directly use lunr.Query, the query language
     * is best used for human entered text rather than program generated text.
     *
     * At its simplest queries can just be a single term, e.g. `hello`, multiple terms are also supported
     * and will be combined with OR, e.g `hello world` will match documents that contain either 'hello'
     * or 'world', though those that contain both will rank higher in the results.
     *
     * Wildcards can be included in terms to match one or more unspecified characters, these wildcards can
     * be inserted anywhere within the term, and more than one wildcard can exist in a single term. Adding
     * wildcards will increase the number of documents that will be found but can also have a negative
     * impact on query performance, especially with wildcards at the beginning of a term.
     *
     * Terms can be restricted to specific fields, e.g. `title:hello`, only documents with the term
     * hello in the title field will match this query. Using a field not present in the index will lead
     * to an error being thrown.
     *
     * Modifiers can also be added to terms, lunr supports edit distance and boost modifiers on terms. A term
     * boost will make documents matching that term score higher, e.g. `foo^5`. Edit distance is also supported
     * to provide fuzzy matching, e.g. 'hello~2' will match documents with hello with an edit distance of 2.
     * Avoid large values for edit distance to improve query performance.
     *
     * Each term also supports a presence modifier. By default a term's presence in document is optional, however
     * this can be changed to either required or prohibited. For a term's presence to be required in a document the
     * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and
     * optionally contain 'bar'. Conversely a leading '-' sets the terms presence to prohibited, i.e. it must not
     * appear in a document, e.g. `-foo bar` is a search for documents that do not contain 'foo' but may contain 'bar'.
     *
     * To escape special characters the backslash character '\' can be used, this allows searches to include
     * characters that would normally be considered modifiers, e.g. `foo\~2` will search for a term "foo~2" instead
     * of attempting to apply a boost of 2 to the search term "foo".
     *
     * @typedef {string} lunr.Index~QueryString
     * @example <caption>Simple single term query</caption>
     * hello
