Searching and Filtering using Paging

Hello,

I am using paging with a csv file (imported into an array) and have added the search and filter modifications to the file. If I try to put a filter on a page I get some strange results and the filter does not run correctly. Here is a copy of my code... Any ideas how to fix this?

Hi Andrew,
Clone the CSV-array is one possible solution for Filtering+Paging,
this way you can search in Main-array and show results from the cloned one, but I didn't find an easy way to highlight searched rows between pages ( so I remove it from now ).
