[xwiki-users] Lucene does not appear to be indexing

Hello, I'm running xwiki-enterprise-2.3.1. After adding a bunch of documents to the wiki, and trying to click on the "Rebuild the Lucene index" link on the LuceneSearch page, it seems to hang indefinitely. A whole bunch of documents are in the wiki that should show up to a search term "Hardware", but none appear when searching using Lucene. When using the old WebSearch page, they all show up. Is there a way to fix this? Thanks, - James Cuzella
