Java - Elasticsearch查询类型

查询类型

queryType	描述	后台代码样例
matchAllQuery	全匹配	QueryBuilder qb = matchAllQuery();
matchQuery	单个匹配	QueryBuilder qb = matchQuery(     "name",     "kimchy elasticsearch" );
multiMatchQuery	多字段单值匹配	QueryBuilder qb = multiMatchQuery(     "kimchy elasticsearch",     "user","message" );
wildcardQuery	模糊匹配	WildcardQueryBuilder queryBuilder1 = QueryBuilders.wildcardQuery("empname","*emp*");

复合查询类型

boolType	描述	后台代码样例
AND	与	BoolQueryBuilder subCodeQuery = QueryBuilders.boolQuery();         WildcardQueryBuilder queryBuilder1 = QueryBuilders.wildcardQuery("empname","*emp*");         WildcardQueryBuilder queryBuilder2 = QueryBuilders.wildcardQuery("gender","*male*");         subCodeQuery.must(queryBuilder1);         subCodeQuery.must(queryBuilder2);
OR	或	类同（subCodeQuery.should）

分页
通过from和size参数进行分页。From定义查询结果开始位置，size定义返回的hits（一条hit对应一条记录）最大数量。

RestFul样例	后台代码样例
{     "from" : 0,"size" : 10,     "query" : {         "term" : { "user": "kimchy" }     } }	SearchResponse response = client.prepareSearch("dept")                 .setTypes("employee")                 .setQuery(queryBuilder)                 .setFrom(0).setSize(2)                 .execute()                 .actionGet();
