Search Function - Highlights all matching rows

I was looking for a search function in the forum and found a couple starting points, but wanted something to highlight ALL rows found, not just one. What I came up with is an include file that I place below the AW grid whenever I need search functionality. As I sometimes struggle with the partial samples here, I thought I would include the whole thing. Maybe I can help someone as much as other posters have helped me. You will just need to change all occurences of "grid." to your grid name/id. (In my production version I use classes on the buttons for nicer formatting.)

<script language="JavaScript" type="text/JavaScript">
        function PerformSearch(clearSearch)
        {
            var rowsArray = [];        // array of row numbers where the text is found (AW is zero relative)
            var found_count = 0;     // the number rows found matching the search text
            //
            // passed vlaue of 'yes' means to clear the highlighted rows - do not perform a search, just clear
            // the text box and clear all highlighted rows.
            if (clearSearch == 'yes')
            {
                // clear any previous text from search box
                SearchBox.setControlText('');
                // set highlight to no rows 
                grid.setSelectionMode("multi-row"); 
                grid.setSelectedRows(rowsArray); 
                // set first row to current
                grid.setCurrentRow(0); 
                grid.setScrollTop(0); 
                //
                return false;
            }
            // search text orignal (used to display number of lines found)
            var searchTextOrig = SearchBox.getControlText(); 
            // upper case of search text (for caseless match) 
            var searchText = SearchBox.getControlText().toUpperCase(); 
            // 
            // if blank then exit 
            if(searchText == '') return false; 
            //
            // loop through all rows and all columns trying to match text (shifted tor upper for caseless match)
            // loop through rows
            for(var r=0;r<grid.getRowCount();r++) 
            { 
                // loop through columns
                for(var c=0;c<grid.getColumnCount();c++) 
                { 
                    var cellContent = grid.getCellText(c,r).toUpperCase(); 
                    var pos = cellContent.indexOf(searchText); 
                    // if text was found, set rowsArray to row nubmer (AW grid is zero relative) and then increment found_count
                    if(pos !=-1)

                        // exit the loop.  Finding one occurrence on the line is enough.
                        break;
                    } 
                }

            // now check the results of the search

                // display message that text was not found (if clearSearch is not 'yes', which is our signal to clear the latest search)
                if (clearSearch != 'yes') 
                {
                    alert('"' + searchTextOrig + '" was not found.');
