在测试Elasticsearch聚合的时候报了一个错误。具体如下:
GET /megacorp/employee/_search { "aggs": { "all_interests": { "terms": { "field": "interests" } } } }
报错信息
{ "error": { "root_cause": [ { "type": "illegal_argument_exception", "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [interests] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead." } ], "type": "search_phase_execution_exception", "reason": "all shards failed", "phase": "query", "grouped": true, "failed_shards": [ { "shard": 0, "index": "megacorp", "node": "wlvuJ0f_SsCxys6ZW5j7eA", "reason": { "type": "illegal_argument_exception", "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [interests] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead." } } ] }, "status": 400 }
解决方案:
1、ElasticSearch5.x的解决方法是这样开启fielddata的:
PUT /megacorp/_mapping/employee { "properties": { "interests": { "type": "text", "fielddata": true } } }
2、版本为ElasticSearch6.x或者7.x时开启fielddata的:
PUT /megacorp/_mapping { "properties": { "interests": { "type": "text", "fielddata": true } } }
