Dear Windev experts,
I have a file with more than 20,000 records, trying to find duplicates or phonetic matches in it, but string comparing takes too long (indexed first),expercially when comparing 2 or more fieds.
I am wandering if there is some smarter ideas to do the de-duplicating or any general ideas in this regard.
much appreciated

Hi Robert,
Use a query as your data source this will prove quicker in sorting, better in finding duplicates (although you still must loop through) and fonetik matches.
The reason is you only have to grab the data you need and not the whole file, you can even just grab duplicates if you try hard.
