boolQueryBuilder.should(QueryBuilders.termQuery("format","jpeg")) 意思是在 bool 查询中添加一个 "should" 条件,即查询 "format" 字段等于 "jpeg" 的文档。

Z try { SearchRequest request = new SearchRequest(INDEX_NAME); SearchSourceBuilder sourceBuilder = new SearchSourceBuilder(); BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery(); if(ids != null && ids.size() > 0){ boolQueryBuilder.must(QueryBuilders.termQuery("id",ids)); }else { // boolQueryBuilder.must(QueryBuilders.matchAllQuery()); } GeoDistanceQueryBuilder geoDistanceQueryBuilder = QueryBuilders.geoDistanceQuery("location") .point(latitude, longitude) .distance(distanceInKm*1000, GeoDistanceQueryBuilder.DEFAULT_DISTANCE_UNIT); // 搜索半径 boolQueryBuilder.filter(geoDistanceQueryBuilder); // sourceBuilder.query(boolQueryBuilder); // sourceBuilder // sourceBuilder request.source().query(boolQueryBuilder); request.source().sort( SortBuilders.geoDistanceSort("location", latitude, longitude) .order(SortOrder.ASC) .unit(DistanceUnit.KILOMETERS) ); request.source().from((currentPage - 1) * PAGE_SIZE).size(PAGE_SIZE); SearchResponse searchResponse = client.search(request, RequestOptions.DEFAULT); return handleResponse(searchResponse,currentPage); } catch (IOException e) { throw new RuntimeException(e); }这个代码有什么bug
这段代码可能存在一个潜在的问题,当ids为null或ids.size()为0时,boolQueryBuilder将不会添加任何查询条件,如果此时将boolQueryBuilder作为查询条件传递给request.source().query(),将会抛出NullPointerException异常。为了避免这种情况,可以在ids为null或ids.size()为0时,将boolQueryBuilder设置为一个匹配所有文档的查询条件,如boolQueryBuilder.must(QueryBuilders.matchAllQuery())。另外,代码中的currentPage和PAGE_SIZE应该是预先定义的常量,需要确保其值正确。
boolQuery.must(QueryBuilders.termsQuery("cigCode.keyword",cigList)); boolQuery.must(QueryBuilders.termQuery("area.keyword",area));转化成es查询
的DSL语句是什么?
答:以下是转化后的ES查询DSL语句:
{
"bool": {
"must": [
{
"terms": {
"cigCode.keyword": [
"cigList"
]
}
},
{
"term": {
"area.keyword": "area"
}
}
]
}
}
