Multiple filters in a single column. Not all filter fields posting to ajax source.

Using Ajax data source

I turned off (hide) global filtering and instead have a filter box in each column. For my date columns, I added two filter fields from and to. DataTables is posting sSearch data for the number of columns, not the number of actual filter fields.

In this particular case I have 16 columns with 19 filter fields

My fix was to add the following code to the datatable initialization for the missing filters.

aoData.push( { "name": "sSearch_17", "value": cleanFilter($('#search_17').val()) } );
aoData.push( { "name": "sSearch_18", "value": cleanFilter($('#search_18').val()) } );
aoData.push( { "name": "sSearch_19", "value": cleanFilter($('#search_19').val()) } );

This isn't really a bug as DataTables is operating as designed and documented in this case ( http://datatables.net/usage/server-side ). Each column can have an individual filter applied to it - DataTables doesn't know anything about the INPUT elements (or SELECT or whatever) that are being used to drive the filter, but each filter can have an individual filter, and there is the global filter. Hence way you are seeing the effect that you are.
