prefix query, 就是前缀检索. 比如商品name中有多个以"Java"开头的document, 检索前缀"Java"时就能检索到所有以"Java"开头的文档. ——扫描所有倒排索引, 性能较差. GET shop/_search{"query":{"prefix":{"name":"java"}}} 3 wildcard query - 通配符检索 扫描所有倒排索引, 性能较差. GET shop/_search...
在intervals query中还支持以下匹配方式: prefix匹配规则:用于匹配以指定前缀开头的词条。 代码语言:javascript 复制 {"intervals":{"field":{"prefix":"pre"}}} wildcard匹配规则:用于匹配符合通配符模式的词条 代码语言:javascript 复制 {"intervals":{"field":{"wildcard":"te*"}}} fuzzy匹配规则:用于匹配与...

Theprefix,wildcard, andregexpqueries operate on terms. If you use them to query ananalyzedfield, they will examine each term in the field, not the field as a whole.((("prefix query", "on analyzed fields")))((("wildcard query", "on analyzed fields")))((("regexp query", "on an...
