Hi, I have installed Elasticsearch after giving up on Zebra. I have follow the the wiki: https://wiki.koha-community.org/wiki/Elasticsearch#Install_elasticsearch and installed latest Elasticsearch through the official repository. My installed version is: curl -XGET 'localhost:9200' { "name" : "Her", "cluster_name" : "elasticsearch", "cluster_uuid" : "yuU4XtZwT1WtK1SH-3Xofw", "version" : { "number" : "2.4.1", "build_hash" : "c67dc32e24162035d18d6fe1e952c4cbcbe79d16", "build_timestamp" : "2016-09-27T18:57:55Z", "build_snapshot" : false, "lucene_version" : "5.5.2" }, "tagline" : "You Know, for Search" } I have run the script perl misc/search_tools/rebuild_elastic_search.pl -v -d like the documentation says and I have this error: Failed to parse mapping [data]: analyzer on field [Local-number] must be set when search_analyzer is set The log on the elasticsearch.log is [2016-09-28 20:27:55,272][DEBUG][action.admin.indices.create] [Her] [koha_dev_biblios] failed to create MapperParsingException[Failed to parse mapping [data]: analyzer on field [Local-number] must be set when search_analyzer is set]; nested: MapperParsingException[analyzer on field [Local-number] must be set when search_analyzer is set]; at org.elasticsearch.index.mapper.MapperService.merge(MapperService.java:291) at org.elasticsearch.cluster.metadata.MetaDataCreateIndexService$1.execute(MetaDataCreateIndexService.java:317) at org.elasticsearch.cluster.ClusterStateUpdateTask.execute(ClusterStateUpdateTask.java:45) at org.elasticsearch.cluster.service.InternalClusterService.runTasksForExecutor(InternalClusterService.java:468) at org.elasticsearch.cluster.service.InternalClusterService$UpdateTask.run(InternalClusterService.java:772) at org.elasticsearch.common.util.concurrent.PrioritizedEsThreadPoolExecutor$TieBreakingPrioritizedRunnable.runAndClean(PrioritizedEsThreadPoolExecutor.java:231) at org.elasticsearch.common.util.concurrent.PrioritizedEsThreadPoolExecutor$TieBreakingPrioritizedRunnable.run(PrioritizedEsThreadPoolExecutor.java:194) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: MapperParsingException[analyzer on field [Local-number] must be set when search_analyzer is set] at org.elasticsearch.index.mapper.core.TypeParsers.parseAnalyzersAndTermVectors(TypeParsers.java:234) at org.elasticsearch.index.mapper.core.TypeParsers.parseTextField(TypeParsers.java:250) at org.elasticsearch.index.mapper.core.StringFieldMapper$TypeParser.parse(StringFieldMapper.java:165) at org.elasticsearch.index.mapper.object.ObjectMapper$TypeParser.parseProperties(ObjectMapper.java:309) at org.elasticsearch.index.mapper.object.ObjectMapper$TypeParser.parseObjectOrDocumentTypeProperties(ObjectMapper.java:222) at org.elasticsearch.index.mapper.object.RootObjectMapper$TypeParser.parse(RootObjectMapper.java:139) at org.elasticsearch.index.mapper.DocumentMapperParser.parse(DocumentMapperParser.java:118) at org.elasticsearch.index.mapper.DocumentMapperParser.parse(DocumentMapperParser.java:99) at org.elasticsearch.index.mapper.MapperService.parse(MapperService.java:549) at org.elasticsearch.index.mapper.MapperService.merge(MapperService.java:319) at org.elasticsearch.index.mapper.MapperService.merge(MapperService.java:289) ... 9 more I'm again at a loss, I believe the problem is on the method: get_elasticsearch_mappings in Koha::ElasticSearch but I don't know how to follow it.! Regards and thank for any help!! Rodrigo
