/**

|
* Enables filtration delay for keeping the browser more responsive while
|
|
* searching for a longer keyword.
|
|
*
|
|
* This can be particularly useful when working with server-side processing,
|
|
* where you wouldn't typically want an Ajax request to be made with every key
|
|
* press the user makes when searching the table.
|
|
*
|
|
* Please note that this plug-in has been deprecated and the `dt-init
|
|
* searchDelay` option in DataTables 1.10 should now be used. This plug-in will
|
|
* not operate with v1.10+.
