How to use findCell when Smart Rendering is enabled?

I have a Grid where Smart Rendering is enabled, one of the operations on that Grid require that I locate several rows that has the same value in a particular Column, Columns are not necessarily sorted on that field, so I cannot assume the rows will be in the same sliding window of the buffer. During the findCell function, it throws an exception, when it crosses the buffer boundary. Is there a way to make this happen within the DHTMLX fraework, or do I need to write special code for this?

For what its worth, I ended up writing my own ajax/mvc to do the search on the db and return the rows to the ui.
