Genau, but don't forget the "delete" :-) If this kind of search is needed quite often and search speed is an issue, it is the easiest solution I can think of. Another approach could be to add a somehow "normalized" representation of the data (removing stop-words from customer names, remove letters from VAT-Codes etc.) > This can mean that the accessories operations will increase > the time to insert/update operations. The impact is not that big from my experience. We use a similar approach to allow a global search over lot's of different tables. fsg -- "Fascinating creatures, phoenixes, they can carry immensely heavy loads, their tears have healing powers and they make highly faithful pets." - J.K.
