There is no need to reindex. However, I also don't quite get what the problem is :) Otis --- Santosh [EMAIL PROTECTED] wrote: hi, when I restart the tomcat . the Index is getting corrupted. If I take the backup of Index and then restarting tomcat. the Index is not working properly.

Re: searchig with special characters

Leading wildcard character (*) is not allowed if you use QueryParser that comes with Lucene. Reason: performance. See many discussions about this on lucene-user mailing list. Also see the search sytax document on the Lucene site. What other characters are you having trouble with? Otis ---

Re: Empty/non-empty field indexing question

Hi Otis What kind of implications does that produce on the search? If I understand correctly that record would not be searched for if the field is not there, correct? But then is there a point putting an empty value in it, if an application will never search for empty values? thanks -pedja Otis

RE: Index delete failing

I got this working. I had to close all index searchers and writer on the index, set them to null and call System.gc() before the delete process. I think windows still thinks writer and searchers are pointing to the index directory even if you close them. Ravi -Original Message- From:

partial updating of lucene

Hi all, I have a question about updating the lucene document. I know that there is no API to do that now. So this is what I am doing in order to update the document with the field title. 1) Get the document from lucene index 2) Remove a field called title and add the same field with a modified

Re: partial updating of lucene

You unstored fields were not stored in the index, only their terms were stored. When you get the document from the index and modify it, those terms are lost when you add the document again. You can either simply create a new document and populate all the fields and add that document to the
