I\'m using fnFilter in datatables and while trying to filter \"inv\" everything else starting with \"inv\" also get filtered. that is \"invc\", \"invk\" are also showing in
Change this
oUserTable.fnFilter($(this).val(), 12);
to
oUserTable.fnFilter("^"+$(this).val()+"$", 12, false, false);
//disabling smart search/regex and apply your own search
Example
