Help on finding text and applying INDEX

Hi Forum,,

I m trying to apply INDEX to the founded words at a single click of the "UI button created".

Is that possible.

This is my try.

app.findGrepPreferences = app.changeGrepPreferences = null;

doc = app.activeDocument.stories.everyItem();

app.findGrepPreferences.findWhat = "Policy";

                              found = app.documents[0].findGrep();

            for (i =0 ; i>found.length; i++) {

                //fnd = found[i];

                              if (found.length > 0)

            doc.indexes[0].topics.add(found);

            app.select[found];

doc.pageReferences.add(found[i], PageReferenceType.currentPage );

}

thanks & regards,
