[xwiki-users] Solr returning "no results"

Hi all, I'm running XWiki 5.1. When running a search with Solr as the default search engine, I'm getting "no results" for every search on both the main wiki and subwikis. If I switch to Lucene, things seem to work fine. I've selected "Reindex" and "Add to index" on both the main wiki and the subwiki Search Administration page, and it finds 10K+ objects and gives me a countdown of items left until it reaches zero. Afterwards there is no change in the search results, still nothing found. I've checked xwiki.cfg and xwiki.properties, and don't see anything. There also appear to be files in the solr index directory. Am I missing something obvious? I don't have much experience with Solr yet...not sure where to start troubleshooting... thanks, aaron
