It's been a while since I used Ext, but if I remember correctly, you can access the store property of the grid control. This gives you an Ext.data.Store which has a filter method that can take either a String or a RegEx. You can then update the grid control (I don't remember if this is required or not, but I seem to remember it being required in Ext 2.1).

Look at the API documentation for Ext.data.store.
