JqGrid upgrade for Boolean search operator

Started to search for some beautiful Table visualisation that and endet up with PHPGrid that offers what i need PhpGrid based on JQGrid from Triland . Some nice php jqgrid development from China the older phpgrid3.0beta (2009-11-14 ) from a Chinese Developer.
Anyway after all some important function was missing for me the Boolean searches like bigger >= and smaller > equal >= to search..
