Hello, I'm using the following request which works fine when using index-name in the request : ``` curl -XGET "http://localhost:9200/ea-v1-2017-06/_search" -H 'Content-Type: application/json' -d' { "version": true, "size": 500, "sort": [ { "norm_first_techno": { "order": "asc", "unmapped_type": "boolean" } } ], "aggs": { "2": { "date_histogram": { "field": "@timestamp", "interval": "30m", "time_zone": "Europe/Berlin", "min_doc_count": 1 } } }, "query": { "bool": { "must": [ { "match_all": {} }, { "range": { "@timestamp": { "gte": 1496312222586, "lte": 1496398622586, "format": "epoch_millis" } } } ] } } }' ``` I have created the alias 'ea' which match ea-\*. And now when i'm using the same request with the alias: > curl -XGET "[http://localhost:9200/ea/\_search](http://localhost:9200/ea/_search) .... Then the curl hang and i've got the following errors in elasticsearch logs: > Failed to execute fetch phase > org.elasticsearch.transport.RemoteTransportException: [barak-ingest01][10.171.6.232:9300][indices:data/read/search[phase/fetch/id]] > Caused by: org.elasticsearch.transport.ResponseHandlerFailureTransportException: java.lang.UnsupportedOperationException > Caused by: java.lang.UnsupportedOperationException > at org.elasticsearch.search.DocValueFormat$3.format(DocValueFormat.java:249) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.search.SearchSortValues.(SearchSortValues.java:51) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.search.SearchHit.sortValues(SearchHit.java:417) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.SearchPhaseController.getHits(SearchPhaseController.java:390) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.SearchPhaseController.merge(SearchPhaseController.java:314) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.FetchSearchPhase.moveToNextPhase(FetchSearchPhase.java:205) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.FetchSearchPhase.lambda$innerRun$2(FetchSearchPhase.java:105) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.CountedCollector.countDown(CountedCollector.java:53) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.CountedCollector.onResult(CountedCollector.java:64) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.FetchSearchPhase$2.innerOnResponse(FetchSearchPhase.java:164) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.FetchSearchPhase$2.innerOnResponse(FetchSearchPhase.java:161) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.SearchActionListener.onResponse(SearchActionListener.java:44) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.SearchActionListener.onResponse(SearchActionListener.java:29) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.ActionListenerResponseHandler.handleResponse(ActionListenerResponseHandler.java:46) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.TransportService$ContextRestoreResponseHandler.handleResponse(TransportService.java:1043) ~[elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.TransportService$DirectResponseChannel.processResponse(TransportService.java:1117) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.TransportService$DirectResponseChannel.sendResponse(TransportService.java:1107) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.TransportService$DirectResponseChannel.sendResponse(TransportService.java:1096) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.DelegatingTransportChannel.sendResponse(DelegatingTransportChannel.java:60) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.RequestHandlerRegistry$TransportChannelWrapper.sendResponse(RequestHandlerRegistry.java:111) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.SearchTransportService$12.messageReceived(SearchTransportService.java:403) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.action.search.SearchTransportService$12.messageReceived(SearchTransportService.java:399) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.RequestHandlerRegistry.processMessageReceived(RequestHandlerRegistry.java:69) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.transport.TransportService$7.doRun(TransportService.java:627) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingAbstractRunnable.doRun(ThreadContext.java:638) [elasticsearch-5.4.1.jar:5.4.1] > at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37) [elasticsearch-5.4.1.jar:5.4.1] > at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) [?:1.8.0\_131] > at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) [?:1.8.0\_131] > at java.lang.Thread.run(Unknown Source) [?:1.8.0\_131] Any ideas how to fix it ?
