In the case you know the keywords (I suppose so, otherwise you would search words, right?) you could use the following strategy: 1. Put your keywords in a hash 2. Split your text into words 3. handle the split words found in the keyword hash according to your "extract rules". Depending on your "extract rules", other/extended methods may be more appropriate. hth, joe -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
