Pipelining data searching is not working what to do?

anupam2017

my jquery is as below

$.fn.dataTable.pipeline = function ( opts ) { // Configuration options var conf = $.extend( { pages: 5, // number of pages to cache url: '', // script url data: null, // function or object with parameters to send to the server // matching how `ajax.data` works in DataTables method: 'GET' // Ajax HTTP method }, opts ); // Private variables for storing the cache var cacheLower = -1; var cacheUpper = null; var cacheLastRequest = null; var cacheLastJson = null; return function ( request, drawCallback, settings ) { var ajax = false; var requestStart = request.start; var drawStart = request.start; var requestLength = request.length; var requestEnd = requestStart + requestLength; if ( settings.clearCache ) { // API requested that the cache be cleared ajax = true; settings.clearCache = false; } else if ( cacheLower < 0 || requestStart < cacheLower || requestEnd > cacheUpper ) { // outside cached data - need to make a request ajax = true; } else if ( JSON.stringify( request.order ) !== JSON.stringify( cacheLastRequest.order ) || JSON.stringify( request.columns ) !== JSON.stringify( cacheLastRequest.columns ) || JSON.stringify( request.search ) !== JSON.stringify( cacheLastRequest.search ) ) { // properties changed (ordering, columns, searching) ajax = true; } // Store the request for checking next time around cacheLastRequest = $.extend( true, {}, request ); if ( ajax ) { // Need data from the server if ( requestStart < cacheLower ) { requestStart = requestStart - (requestLength*(conf.pages-1)); if ( requestStart < 0 ) { requestStart = 0; } } cacheLower = requestStart; cacheUpper = requestStart + (requestLength * conf.pages); request.start = requestStart; request.length = requestLength*conf.pages; // Provide the same `data` options as DataTables. if ( $.isFunction ( conf.data ) ) { // As a function it is executed with the data object as an arg // for manipulation. If an object is returned, it is used as the // data object to submit var d = conf.data( request ); if ( d ) { $.extend( request, d ); } } else if ( $.isPlainObject( conf.data ) ) { // As an object, the data given extends the default $.extend( request, conf.data ); } settings.jqXHR = $.ajax( { "type": conf.method, "url": conf.url, "data": request, "dataType": "json", "cache": false, "success": function ( json ) { cacheLastJson = $.extend(true, {}, json); if ( cacheLower != drawStart ) { json.data.splice( 0, drawStart-cacheLower ); } if ( requestLength >= -1 ) { json.data.splice( requestLength, json.data.length ); } drawCallback( json ); } } ); } else { json = $.extend( true, {}, cacheLastJson ); json.draw = request.draw; // Update the echo for each response json.data.splice( 0, requestStart-cacheLower ); json.data.splice( requestLength, json.data.length ); drawCallback(json); } } }; // Register an API method that will empty the pipelined data, forcing an Ajax // fetch on the next draw (i.e. `table.clearPipeline().draw()`) $.fn.dataTable.Api.register( 'clearPipeline()', function () { return this.iterator( 'table', function ( settings ) { settings.clearCache = true; } ); } ); $(document).ready(function() { $('#data-table').DataTable( { "processing": true, "serverSide": true, "bFilter": true, "bSortable": true, "bRetrieve": true, "aoColumns": [{"sType":"string"}], "ajax": $.fn.dataTable.pipeline( { url: 'scripts/server_processing.php', pages:100// number of pages to cache } ), "search": { "regex": true }, "order": [[ 0, "desc" ]], "columnDefs": [{ "targets": 19, "orderable": false }], } ); } );

Searching and desc and asc order is not worlking here........Thanks in advance....!!!!
