How filter in multiple columns?

Can i pass the value of one input text to filter grid in more the one column?

I want filter in all collunms using one textbox, its possible?

the documentation describes the filtering options and API

docs.dhtmlx.com/doku.php?id=dhtmlxgrid:filtering

you can build up complex rules to link the input box to several columns but if you try and filter several columns for the same value then you will only get rows where all the relevant columns have that value - is that what you are after?
