After upgrading from v0.90.1 -\> v0.90.5, we noticed that some of our has\_child filter queries started to fail on some shards. Following is the request - curl -x '' -s -XPOST '[http://localhost:9201/data\_index\_20131011/vendor/\_search?from=0&size=2](http://localhost:9201/data_index_20131011/vendor/_search?from=0&size=2)' -d ' { "filter" : { "has\_child" : { "query" : { "match" : { "set\_aside\_descriptions" : { "query" : "No set aside used." } } }, "type" : "transaction" } } } ' And the error trace from logs - [2013-10-24 08:54:07,330][TRACE][search] [mach2.node] Query phase failed org.elasticsearch.search.query.QueryPhaseExecutionException: [data\_index\_20131011][0]: query[ConstantScore(cache(\_type:vendor))],from[0],size[2]: Query Failed [Failed to execute main query] at org.elasticsearch.search.query.QueryPhase.execute(QueryPhase.java:138) at org.elasticsearch.search.SearchService.executeQueryPhase(SearchService.java:219) at org.elasticsearch.search.action.SearchServiceTransportAction$SearchQueryTransportHandler.messageReceived(SearchServiceTransportAction.java:623) at org.elasticsearch.search.action.SearchServiceTransportAction$SearchQueryTransportHandler.messageReceived(SearchServiceTransportAction.java:612) at org.elasticsearch.transport.netty.MessageChannelHandler$RequestHandler.run(MessageChannelHandler.java:269) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) Caused by: java.lang.NullPointerException at org.elasticsearch.common.lucene.docset.MatchDocIdSet.shortCircuit(MatchDocIdSet.java:82) at org.elasticsearch.index.search.child.HasChildFilter$ParentDocSet.matchDoc(HasChildFilter.java:174) at org.elasticsearch.common.lucene.docset.MatchDocIdSet.get(MatchDocIdSet.java:69) at org.elasticsearch.common.lucene.search.FilteredCollector.collect(FilteredCollector.java:61) at org.apache.lucene.search.Scorer.score(Scorer.java:65) at org.apache.lucene.search.ConstantScoreQuery$ConstantScorer.score(ConstantScoreQuery.java:245) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:624) at org.elasticsearch.search.internal.ContextIndexSearcher.search(ContextIndexSearcher.java:162) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:488) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:444) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:281) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:269) at org.elasticsearch.search.query.QueryPhase.execute(QueryPhase.java:134) ... 7 more The same query works fine in v0.90.1. It's tough to provide a gist to replicate because the error is data dependent, it only happens for some queries. For e.g. "query" : "blah blah" works fine but "query" : "No set aside used." fails. Also the whole index data size is more than a GB. This is blocking our upgrade to v0.90.5 so any help would be much appreciated.
