Pls kindly give a specific example so that we can replicate it and find a solution for you. Tks,

I see it. With newer versions of DataTables we have a property called searchMode which can be "default", "and", "or", "exact" or any combination of those values ("and|exact", etc):

https://www.koolreport.com/docs/datagrid/datatables/#custom-attributes-searchmode-(%22or%22-since-version-%3E=-3.0.0,-%22and|exact%22-since-version-6.0.0)

<?php 
DataTables::create(array(
    ...
    "searchMode" => "or|and", //"and|exact", "or|and|exact", "exact|or"

With default search mode, to search for a phrase with blank space in them you can include the phrase inside double quote like "sales manager". If you don't want to use double quote, you can set "searchMode" => "exact".
