You might want to check the Highlighter.net package (in Lucene.Net/contrib from their website). They highlight matched words. They use StandardAnalyzer in their example but I wrapped a PorterStemmer around it and asked it to highlight words with same stem and it was able to do it. One way I had in mind was to create a tokenstream, check if the tokentext is the same as the suggested stem, if yes use the token.startoffset, token.endoffset to extract the actual text. Of course its easier said than done ;-) > We need to only return the highest relevant suggestions, based on: > 1.) Term frequency in index > 2.) Levenshtein distance score Add to that there could be multiple indexes so results from multiple indexes need to be intelligently merged. > Sorry, for the exhausting email and lets make Beagle rock! :-) Yayyyyyyyyyyyy !!! - dBera -- ----------------------------------------------------- Debajyoti Bera @ http://dtecht.blogspot.com beagle / KDE fan Mandriva / Inspiron-1100 user
