Take a look at the "MoreLikeThis" class in the "contrib" section will reduce large amounts of text like your example paragraphs to only the "important" words which are useful for searching and provide you with a query object you can run. The disadvantage of trying to feed your example content through the default QueryParser is: 1) It will reject any illegal query syntax (e.g. unclosed brackets ) in your text 2) It may throw a TooManyClauses exception if the text is too long (the default limit is 1024 terms) 3) Your query is likely to take a long time to execute because of the large number of query terms used.

But I have one doubt that I couldn't resolve reading the docs and the demo sources: All the examples just search in the index by just a single word, but I need to know if it's possible to search in the index using a reference text. Let me explain: supose that a web user reaches the search page of my commercial website and needs to find a solution about some trouble. Then he types a long text (about three or four paragraphs) and next clicks on the search button. In this cenario, it's that possible to perform a search through the index using that long text? What I need it's something just like the Help system of microsoft office. I apreciate if someone could give me some directions. Best Regards. Ricardo Pereira - Brazil PS: If someone finds some error in this text, please submit me the corrections. I'll apreciate the indications. I don't have money to do a great english course and I have try to learn by myself usind the BBC site. ___________________________________________________________ The all-new Yahoo!
