报错一

org.elasticsearch.ElasticsearchStatusException: Elasticsearch exception [type=search_phase_execution_exception, reason=all shards failed]

	Suppressed: org.elasticsearch.client.ResponseException: method [POST], host [http://localhost:9200], URI [/wzx-test/_search?pre_filter_shard_size=128&typed_keys=true&max_concurrent_shard_requests=5&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true&ignore_throttled=true&search_type=query_then_fetch&batched_reduce_size=512&ccs_minimize_roundtrips=true], status line [HTTP/1.1 400 Bad Request]

报错原因：我在创建索引和字段的时候，name字段不是索引字段，当用精准查询的时候，就报错如上图所示

解决方案：将name字段设置成true，问题解决

PUT /wzx-test
{"mappings": {"properties": {"car_num": {"type": "keyword","index": false},"name": {"type": "keyword","index": true},"age": {"type": "keyword","index": false}}}
}
