Hi, I'm new to lucene. I am working on an application that searches HTML, pdf, txt and word documents. I wanted to know how to overwrite the indexes for a document which has been modified. Should I overwrite that file, delete all the existing indexes and reindex all the files in the dirctory or is there a way to reindex only that particular file. Also I wanted to know, to index different kind of files for example in my case HTML,pdf,TXT and word docs do I need to write different indexing programs or can I use the same indexing program. Thanks in advance. Anushri
