Qww.Ctls.GlobalSearch = {};

/** 
Constructs a new Qww.Ctls.GlobalSearch.Mgr instance.

@class JavaScript control to search across multiple fields (listboxes) within an application. Note that 
you should create copies of the listboxes you wish to use which are utilised only by this control. For example if you are 
already showing LBCOUNTRY as a listbox control on your page, create a copy of this listbox named LBCOUNTRY_SEARCH and use this 
in conjunction with the Qww.Ctls.GlobalSearch.Mgr control.<br />

@param {Object} cfg JSON object to configure Qww.Ctls.GlobalSearch.Mgr.

@param {String} cfg.ResultsElementId Element to show search results in.

@param {String} cfg.SearchTextBoxId ID of text box where search term is entered.

@param {Qww.Ctls.GlobalSearch.Field[]} cfg.Fields Array of fields to search in the QlikView document.

@param {String} [cfg.Theme=Default] Theme to use (this string gets used in css class names, for example QwwJs_GlobalSearch-NoMatchesFound-ThemeName).

@param {Bool} [cfg.AutomaticallyClearSearchString=false] If set to true the search box is cleared whenever results are selected.

@param {Bool} [cfg.CloseSearch=false] If set to true then each time the search command is sent to QlikView Server 
the search will also be 'closed' meaning that the matching listbox items will be selected (and any other QlikView objects 
will be updated accordingly).

@param {Integer} [cfg.SearchInterval=500] Rather than sending new search requests as soon as the user starts typing, the search control 
waits this amount of milliseconds after the last character was typed then sends the search.

@param {Function} [cfg.OnRenderResultsSection] Function to run to render custom results. Function will have the following 
signature: function(results, lbId, lbTitle, lbMatchString, lbNoMatchString, maxLengthOfMatchStringToShow, 
maxNumberOfResultsToShow, lbSelectAllText, lbReduceResultstext).

@param {Function} [cfg.OnInitialised] Function to call when the control has been initialised.

@param {Function} [cfg.OnRenderBegin] Function to call when the control is about to re-render.

@param {Function} [cfg.OnRenderComplete] Function to call when the control is about to complete rendering.

@param {Function} [cfg.OnBeforeCloseSearch] Function to call before the search results close. Should be 
of the form function(searchCtl, isFromCloseButton). The isFromCloseButton is false if the search is closing for 
a reason other than the [X] was clicked, for example when the user clears the search box text the search closes. 
If you return false from this function the closing of the search will be cancelled.

@param {Function} [cfg.OnSearchClosed] Function to call after the search results close. Should be 
of the form function(searchCtl, isFromCloseButton). The isFromCloseButton is false if the search is closing for 
a reason other than the [X] was clicked, for example when the user clears the search box text the search closes. 

@param {Function} [cfg.OnGetSearchString|function(str){return "*" + str + "*";}] Function to call to return the search 
string to be sent to QlikView Server. Defaults to a 'standard' *search_string* pattern. NOTE this is only called when the 
str.length > 0, otherwise '***' will be sent as the search string to clear the search.

@param {Function} [cfg.OnSearchInitiated] Function to call when the search initiates. Useful, for example, to 
show an animated spinner to give the user immediate feedback that a search is in progress.

@param {Function} [cfg.OnSearchCompleted] Function to call after the search has completed. Useful, for example, to 
hide an animated spinner which has been shown on the OnSearchInitiated event.

@param {Function} [me.Cfg.OnSearchPerformed] Function to call when a search is run against the server. The function 
should accept the parameters (Qww.Ctls.GlobalSearch.Mgr, searchString).
