Elasticsearch Query DSL-Full text queries Full text queries 全文搜索 Intervals允许对匹配项的顺序和接近度进行细粒度控制。 Intervals Match标准的全文搜索方式 GET/_search{"query":{"match":{"message":{"query":"this is a test"}}}} 它背后的查询机

(1) GET /product/book/_search?q=2020#搜索到3条数据(2) GET /product/book/_search?q=2020-01-01#搜索到3条数据(3) GET /product/book/_search?q=post_date:2020-01-01#搜索到1条数据 接下来我们逐个分析下为什么会有这些结果出现 第(1),(2)个查询用的是_all元数据,三条演示数据进行分词后所拼...
sourceBuilder.query(QueryBuilders.matchQuery("message", "this out elasticsearch")); 1. 2. 其大体步骤如下: 首先对this out Elasticsearch分词,最终返回结果为 this、out、Elasticsearch,然后分别去库中进行匹配,默认只要一个匹配,就认为匹配,但会加入一个匹配程度(关联度),用scoce分数表示。 1.2 match query...
