Hi, I am new to ElasticSearch. I am using ElasticSearch 0.90.5 for search module of my application. In my application, i will be using multi-tenant setup with alias for each user. I had a use case such that i want to sort results based on id field. Hence i included sort based on \_uid as below **client.prepareSearch(aliases).addSort(SortBuilders.fieldSort("\_uid").order(SortOrder.DESC)).setTypes(tableNames);** I am getting exception like below, _org.elasticsearch.action.search.SearchPhaseExecutionException: Failed to execute phase [query\_fetch], all shards failed; shardFailures {[b98tpRjZTqa1DRJXmXDOAg][29][4]: RemoteTransportException[[node2][inet[/172.20.6.215:9301]][search/phase/query+fetch]]; nested: SearchParseException[[29][4]: from[0],size[5]: Parse Failure [Failed to parse source [{"from":0,"size":5,"filter":{"query":{"field":{"content":"engineer"}}},"sort":[{"\_uid":{"order":"asc"}}]}]]]; nested: SearchParseException[[29][4]: from[0],size[5]: Parse Failure [No mapping found for [\_uid] in order to sort on]]; } at org.elasticsearch.action.search.type.TransportSearchTypeAction$BaseAsyncAction.onFirstPhaseResult(TransportSearchTypeAction.java:272) at org.elasticsearch.action.search.type.TransportSearchTypeAction$BaseAsyncAction$3.onFailure(TransportSearchTypeAction.java:224) at org.elasticsearch.search.action.SearchServiceTransportAction$7.handleException(SearchServiceTransportAction.java:324) at org.elasticsearch.transport.netty.MessageChannelHandler.handleException(MessageChannelHandler.java:180) at org.elasticsearch.transport.netty.MessageChannelHandler.handlerResponseError(MessageChannelHandler.java:170) at org.elasticsearch.transport.netty.MessageChannelHandler.messageReceived(MessageChannelHandler.java:122) at org.elasticsearch.common.netty.channel.SimpleChannelUpstreamHandler.handleUpstream(SimpleChannelUpstreamHandler.java:70) at org.elasticsearch.common.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:564) at org.elasticsearch.common.netty.channel.DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(DefaultChannelPipeline.java:791) at org.elasticsearch.common.netty.channel.Channels.fireMessageReceived(Channels.java:296) at org.elasticsearch.common.netty.handler.codec.frame.FrameDecoder.unfoldAndFireMessageReceived(FrameDecoder.java:462) at org.elasticsearch.common.netty.handler.codec.frame.FrameDecoder.callDecode(FrameDecoder.java:443) at org.elasticsearch.common.netty.handler.codec.frame.FrameDecoder.messageReceived(FrameDecoder.java:303) at org.elasticsearch.common.netty.channel.SimpleChannelUpstreamHandler.handleUpstream(SimpleChannelUpstreamHandler.java:70) at org.elasticsearch.common.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:564) at org.elasticsearch.common.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:559) at org.elasticsearch.common.netty.channel.Channels.fireMessageReceived(Channels.java:268) at org.elasticsearch.common.netty.channel.Channels.fireMessageReceived(Channels.java:255) at org.elasticsearch.common.netty.channel.socket.nio.NioWorker.read(NioWorker.java:88) at org.elasticsearch.common.netty.channel.socket.nio.AbstractNioWorker.process(AbstractNioWorker.java:109) at org.elasticsearch.common.netty.channel.socket.nio.AbstractNioSelector.run(AbstractNioSelector.java:312) at org.elasticsearch.common.netty.channel.socket.nio.AbstractNioWorker.run(AbstractNioWorker.java:90) at org.elasticsearch.common.netty.channel.socket.nio.NioWorker.run(NioWorker.java:178) at org.elasticsearch.common.netty.util.ThreadRenamingRunnable.run(ThreadRenamingRunnable.java:108) at org.elasticsearch.common.netty.util.internal.DeadLockProofWorker$1.run(DeadLockProofWorker.java:42) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619)_ But i am getting results too, not sure whats the problem is.

I have the same problem here, not sure if this issue has been resolved. Here's my error Caused by: org.elasticsearch.search.SearchParseException: [reservenamesearch][1]: from[0],size[1]: Parse Failure [Failed to parse source [{ "from" : 0, "size" : 1, "sort" : [ { "\_score" : { "order" : "desc" } , "\_uid" : { "order" : "asc" } } ], "query" : { "filtered" : { "query" : { "match\_all" : { } }, "filter" : { "and" : [ { "term" : { "isPendingRegistration" : false } }, { "query" : { "query\_string" : { "default\_field" : "VersionIdentifier", "query" : "T1120938" } } } ] } } } }]] ---
