Subject [jira] Commented: (LUCENE-1026) Provide a simple way to concurrently access a Lucene index from multiple threads
Date Mon, 10 Mar 2008 04:51:46 GMT


Asgeir Frimannsson commented on LUCENE-1026:

Is there any specific reason why this indexaccessor is limited to FSDirectory based indexes?
I see FSDirectory.getFile() is used as a unique key in the list of IndexAccessors in the factory.
However, it seems more natural to use dir.getLockID() for this purpose. Then it would be possible
to use a generic Directory rather than the file-system specific FSDirectory.

> For building interactive indexes accessed through a network/internet (multiple threads).
> This builds upon the LuceneIndexAccessor patch. That patch was not very newbie friendly
and did not properly handle MultiSearchers (or at the least made it easy to get into trouble).
> This patch simplifies things and provides out of the box support for sharing the IndexAccessors
across threads. There is also a simple test class and example SearchServer to get you started.
> Future revisions will be zipped.
> Works pretty solid as is, but could use the ability to warm new Searchers.
