例如:
GET patentarticle/_search
{
"from": 0,
"size": 1,
"query": {
"query_string": {
"default_field": "*",
"query": "claimText:\"聚乙烯\" AND id:xxxxxxxxx",
"analyzer": "ik_syn_smart"
}
},
"_source": true,
"explain": true
}
这是一个很简单的查询语句, 搜索claimText包含聚乙烯, 并且id是xxxxxxxxx的文档, 但是就是无法命中, 并且查看了该文档的claimText字段索引生成的token数组:

可以看到是有聚乙烯这个token的, 并且还不止一个, 那为什么搜不出来呢?
原因就是: 查询过程是先将聚乙烯进行分词, 如拆分为聚乙烯和乙烯, 然后去索引底层去命中token数组中带聚乙烯和乙烯的文档, 并且聚乙烯和乙烯的前后顺序要一致, 否则无法命中.
这其实和match_phrase的查询原理是一样的.
解决方法呢: 设置slop , 去掉""使用普通的match查询, 或者更换查询分词器缩小分词范围, 都可以解决, 看具体的业务了.
另外总结下:如果某个词能在索引中查出来,但是在某个id中查不出来怎么办?
1.使用explain分析下,这个搜索词在其他文档中是如何命中的, 就能观察到搜索词在查询过程中如何进行的分词, 以及如何命中文档.
2.在拿这些分词去查询不到的id中进行验证,就能查到根本原因
