My case is more or less similar, but I don't have that many fields. I have been using MultiQueryFieldParser and then Highlighter to figure out which fields have a match and then I get the relevant fragment with the right term highlighter. I have a question for you, though. Are you parsing the XML for each document after you get the results of a query or are you using stored fields? What XML parser are you using? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
