elasticsearch怎么使用？

用2個Map作為傳參，一個是must，一個是should。代碼如下：

//創建查詢

SearchRequestBuilder srb = client.prepareSearch(INDEX);

srb.setTypes(ASK_TYPE);

srb.setSearchType(SearchType.DFS_QUERY_THEN_FETCH);

//分頁

srb.setFrom((pageNo - 1) * pageSize).setSize(pageSize);

//按時間倒序

SortBuilder sortBuilder = SortBuilders.fieldSort("date").order(SortOrder.DESC);

srb.addAggregation(aggregation);//聚合

srb.addSort(sortBuilder);//排序

/**********************主要看這里 start*********************************/

if(null != mustMap && mustMap.size() > 0){

//創建一個查詢

BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();

//這里查詢的條件用map傳遞

for(String key : mustMap.keySet()){

queryBuilder.must(QueryBuilders.termQuery(key,mustMap.get(key)));

}

//這里查詢的條件用map傳遞

for(String key : shouldMap.keySet()){

queryBuilder.should(QueryBuilders.termQuery(key,mustMap.get(key)));

}

//查詢

srb.setQuery(queryBuilder);

}

/**********************主要看這里 end*********************************/

//請求

SearchResponse response = srb.get();
