各种 Query 及 QueryBuilder

返回：spring data elasticSearch

• 要构建 QueryBuilder，我们可以使用工具类 QueryBuilders，里面有大量的方法用来完成各种各样的 QueryBuilder 的构建，字符串的、Boolean 型的、match 的、地理范围的等等。
• 要构建 SortBuilder，可以使用 SortBuilders 来完成各种排序。
• 然后就可以通过 NativeSearchQueryBuilder 来组合这些 QueryBuilder 和 SortBuilder，再组合分页的参数等等，最终就能得到一个 SearchQuery 了。

GeoShapeQueryBuilder

基于形状和索引形状的关系的过滤器

RegexpQueryBuilder

与包含具有指定正则表达式的术语的文档匹配的查询。

RangeQueryBuilder

一个查询，该查询匹配一系列术语内的文档。

PrefixQueryBuilder

与包含带有指定前缀的术语的文档匹配的查询。

FuzzyQueryBuilder

使用模糊查询匹配文档的查询。

TermQueryBuilder

与包含术语的文档匹配的查询。

BoolQueryBuilder

must的性能要低一些，为什么？因为他要进行打分评估，也就是说要进行_score，而filter则不会。

与文档匹配的查询，该文档与其他查询的布尔组合匹配。
