Hi there, I just subscribed to this list and have a little Problem:
I am using lucene for incremental indexing (yes, I read the FAQ! dont try to convince me to rebuild the index periodically from scratch :) ). Now the problem seems to be that lucene is not able to perform index modifications and parallel search requests. After my simple approaches failed, I finnaly implemented the recomended way to have an index that is modified and create a copy of that index for searches. I do all this with proper Thread synchronization (at least I hope so). Before I copy the index, I do close the index-writer and index-reader working on that index, then copy and reopen the index-writer and -reader on the new copy. Next I close the index-searcher and reopen it on the index that has been copied before. Now my problem is that when I receive a delete event and want to remove a document from the index by a special field (in my case the URI), I get a IOException with the message "Lock obtain timed out". I tried lucene 1.3-rc1, 1.3-rc2 and 1.3-rc3 all with the same result. Any suggestions would be very welcome :) Thank you so far Jörg Hohwiller BTW: I attatched the relevant source code (but removed imports, etc. so that it does not contain any confidential information). Maybe this answers the first of your questions.
