-/**
- * 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
Simple single term query
- * hello
- * @example
Multiple term query
- * hello world
- * @example
term scoped to a field
- * title:hello
- * @example
term with a boost of 10
- * hello^10
- * @example
term with an edit distance of 2
- * hello~2
- * @example
terms with presence modifiers
- * -foo +bar baz

-// About: Examples
-//
-// These working examples, complete with fully commented code, illustrate a few
-// ways in which this plugin can be used.
-//
-// Throttle - http://benalman.com/code/projects/jquery-throttle-debounce/examples/throttle/
-// Debounce - http://benalman.com/code/projects/jquery-throttle-debounce/examples/debounce/
-//
-// About: Support and Testing
-//
-// Information about what version or versions of jQuery this plugin has been
-// tested with, what browsers it has been tested in, and where the unit tests
-// reside (so you can test it yourself).
-//
-// jQuery Versions - none, 1.3.2, 1.4.2
-// Browsers Tested - Internet Explorer 6-8, Firefox 2-3.6, Safari 3-4, Chrome 4-5, Opera 9.6-10.1.
-// Unit Tests - http://benalman.com/code/projects/jquery-throttle-debounce/unit/
-//
-// About: Release History
-//
-// 1.1 - (3/7/2010) Fixed a bug in where trailing callbacks
-// executed later than they should. Reworked a fair amount of internal
-// logic as well.
-// 1.0 - (3/6/2010) Initial release as a stand-alone project. Migrated over
-// from jquery-misc repo v0.4 to jquery-throttle repo v1.0, added the
-// no_trailing throttle parameter and debounce functionality.
-//
-// Topic: Note for non-jQuery users
-//
-// jQuery isn't actually required for this plugin, because nothing internal
-// uses any jQuery methods or properties. jQuery is just used as a namespace
-// under which these methods can exist.
-//
-// Since jQuery isn't actually required for this plugin, if jQuery doesn't exist
-// when this plugin is loaded, the method described below will be created in
-// the `Cowboy` namespace. Usage will be exactly the same, but instead of
-// $.method() or jQuery.method(), you'll need to use Cowboy.method().
-
-(function(window,undefined){
- '$:nomunge'; // Used by YUI compressor.
-
- // Since jQuery really isn't required for this plugin, use `jQuery` as the
- // namespace only if it already exists, otherwise use the `Cowboy` namespace,
- // creating it if necessary.
- var $ = window.jQuery || window.Cowboy || ( window.Cowboy = {} ),
-
- // Internal method reference.
- jq_throttle;
-
- // Method: jQuery.throttle
- //
- // Throttle execution of a function. Especially useful for rate limiting
- // execution of handlers on events like resize and scroll. If you want to
- // rate-limit execution of a function to a single time, see the
- // method.
- //
- // In this visualization, | is a throttled-function call and X is the actual
- // callback execution:
- //
- // > Throttled with `no_trailing` specified as false or unspecified:
- // > ||||||||||||||||||||||||| (pause) |||||||||||||||||||||||||
- // > X X X X X X X X X X X X
- // >
- // > Throttled with `no_trailing` specified as true:
- // > ||||||||||||||||||||||||| (pause) |||||||||||||||||||||||||
- // > X X X X X X X X X X
- //
- // Usage:
- //
- // > var throttled = jQuery.throttle( delay, [ no_trailing, ] callback );
- // >
- // > jQuery('selector').bind( 'someevent', throttled );
- // > jQuery('selector').unbind( 'someevent', throttled );
- //
- // This also works in jQuery 1.4+:
- //
- // > jQuery('selector').bind( 'someevent', jQuery.throttle( delay, [ no_trailing, ] callback ) );
- // > jQuery('selector').unbind( 'someevent', callback );
- //
- // Arguments:
- //
- // delay - (Number) A zero-or-greater delay in milliseconds. For event
- // callbacks, values around 100 or 250 (or even higher) are most useful.
- // no_trailing - (Boolean) Optional, defaults to false. If no_trailing is
- // true, callback will only execute every `delay` milliseconds while the
- // throttled-function is being called. If no_trailing is false or
- // unspecified, callback will be executed one final time after the last
- // throttled-function call. (After the throttled-function has not been
- // called for `delay` milliseconds, the internal counter is reset)
- // callback - (Function) A function to be executed after delay milliseconds.
- // The `this` context and all arguments are passed through, as-is, to
- // `callback` when the throttled-function is executed.
