情況：
頁面查詢ES數(shù)據(jù)，Java查詢報(bào)這個錯誤，但是，通過打印的語句，構(gòu)建curl
查詢時候又是正常的，這就讓我很費(fèi)解。

報(bào)錯信息：

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [aaa] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory."
      }
    ],
    "type": "search_phase_execution_exception",
    "reason": "all shards failed",
    "phase": "query",
    "grouped": true,

        }
      }
    ],

      "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [aaa] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory."
    }
  },

}

網(wǎng)上的解決辦法：
https://blog.csdn.net/qq_16417621/article/details/105859887

這個解決辦法其實(shí)是正確的，但是，有個前提條件，我們已經(jīng)導(dǎo)入過模板，所以，可以直接修改模板
而且，這個帖子中的語句，是基于 ES7 的。我所在環(huán)境是ES5的，所以，加fielddata=true配置時，還報(bào)錯。

具體解決辦法：
我直接重新創(chuàng)建模板，然后，重新刷一次數(shù)據(jù)，解決問題。

導(dǎo)入模板語句：

curl -X PUT -u elastic:123456  "http://127.0.0.1:9200/_template/aaa_bbb_info_temple" -H 'Content-Type: application/json' -d'{"template":"aaa_bbb_*","settings":{"index":{"mapping":{"ignore_malformed":"true"},"refresh_interval":"20s","number_of_shards":"5","translog":{"flush_threshold_size":"512mb","sync_interval":"60s","durability":"async"},"number_of_replicas":"1"}},"mappings":{"default":{"properties":{"aaa":{"store":true,"type":"keyword"}}}}}'

查詢導(dǎo)入是否成功：文章來源地址http://www.zghlxwxcb.cn/news/detail-599220.html

curl -H "Content-Type:application/json" -XGET -u elastic:123456 '192.168.92.82:9222/_template/aaa_bbb_info_temple' > aaa_bbb_info_temple.txt
