--- Begin Message ---Hello sir Thank u for replying. But my query is not regarding updating indexes, optimizing indexes and such others. Sorry sir may be my earlier question was not that clear. Here i elaborate my problem clearly. I have to develop a search engine for my s website. We have some data on the local common drive which is accessible o everyone. The drive contains directories which further contain html pages, pdf files, power point presenations, xml files, word documents , xls files etc. Now the requirement is that people of my department wnat a website which contains a search engine so that they are able to search any file from this drive. So i created a website and i am trying to make a search engine for my site. I have used Lucene to create the search engine.As u must be knowing Lucene first indexes all the files and then we can search them. Till here everything goes fine. But when I integrate lucene with my web server i.e. Apache Tomcat it just indexs Html documents and text documents. But my requirement is to index all files on the common drive i.e. .pdf,.xml,. ppt, .xls etc. For solution to this problem I had reffered to the FAQ's of lucene at the following link http://wiki.apache.org/jakarta-lucene/LuceneFAQ. There Ii searched for "How to index pdf files" , power point presentations etc. Question 34 is the solution for PDF files. Please do refer to it may be u understand my problem better. It says that we require a parser for this so that it can extract text from PDF files and convert it into a text file. Now after extracting it, Lucene converts that PDF document to text document. Then Lucene indexes it . Now when I search it in my browser the file is searched and displayed as a text document which is not required. I want it to be display it as PDF documents. So please give me a solution for this and tell me how can this problem be solved. "THAT is HOW CAN I INDEX and SEARCH .pdf, .ppt,. xml, .doc etc DOCUMENTS WITH LUCENE." I WILL BE REALLY HANKFUL IF U SOLVE MY PROBLEM.

Hi Erik, Might it be as easy as creating a SpanWilcardQuery that transforms into a SpanOrQuery of SpanTermQuery's, and then use a SpanNearQuery of SpanWildcardQuery's? You could use a WildcardTermEnum.to generate the list of terms for the SpanOrQuery. This would have some issues like computing the idf as the sum of all the pattern-matched terms, but it looks like that issue still exists with WildcardQuery too. I haven't done much with SpanQuery's so this might not work out so simply, or be acceptably efficient.
