Key: LUCENE-3691
URL: https://issues.apache.org/jira/browse/LUCENE-3691
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 2.9.1
Environment: Ubuntu 10.04
Lucene run under embedded Solr 1.4.0 (all behind a tomcat which is probably
irrelevant)
Reporter: Antoniya Statelova
Priority: Minor
Searching for "\u3000x", "x\u3000" and everything similar works fine; however,
searching for just "\u3000" throws the following exception:
core.SolrCore - org.apache.solr.common.SolrException:

Avoiding querying for empty strings fixes the problem, but I'm not sure this is
expected behavior. Solr is queried using a WhitespaceTokenizer on the query.
I'm posting the issue here since it seems like a problem with Lucene vs Solr,
sorry if I'm wrong. ~Antoniya
