When trying to attach a commit in in Diffusion ( Diffusion->commit->Edit Maniphest Tasks) the popup is not populated and returns the following Ajax error:
for (;;);{"error":{"code":"HTTPFutureResponseStatusHTTP","info":"[HTTP\/400] \n{\"error\":\"SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[8o8Vr1EhR6W5tM8q7KKxPQ][phabricator][2]: SearchParseException[[phabricator][2]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\\\"query\\\":{\\\"filtered\\\":{\\\"query\\\":{\\\"bool\\\":{\\\"must\\\":[{\\\"bool\\\":{\\\"should\\\":[{\\\"text\\\":{\\\"relationship.auth.phid\\\":{\\\"query\\\":\\\"PHID-USER-kn2tz3idxpkdnij52pn6\\\",\\\"type\\\":\\\"phrase\\\"}}}]}}]}},\\\"filter\\\":{\\\"and\\\":[{\\\"exists\\\":{\\\"field\\\":\\\"relationship.open.phid\\\"}}]..."},"payload":null}
System is using ElasticSearch Version: 1.2.1, Build: 6c95b75/2014-06-03T15:02:52Z, JVM: 1.7.0_55
Regular search works fine.
