fumai, you are right the solutions provided above do work.
However I am looking for something faster which would be similar to the find all instances which is available from word xp and on. With such a search it would only take one line of code to fill an array. That is why I used Adobe Scripting to compare, because even though adobe incopy & indesign are slowwww saving a search to an array is considerably quicker with one line of code.
if I am still confusing you let me know and I will try again to explain my issue Thanks Fumei for your passion
