elasticsearch - QueryBuilders数组 Elasticsearch 2.4

Question

 QueryBuilder missingFiletr = QueryHelper.andQuery(incCatsEmptyFilter, excCatsEmptyFilter, incEmptyFilter, excEmptyFilter);

我正在调用andQuery方法以及和FilterBuilders的所有参数()
现在要去 filterBuilders 数组，我要将其提取到 filterBuilder 中，因为我想对所有queryBuilders进行和。格式正确吗

public static QueryBuilder andQuery(QueryBuilder... filterBuilders) {
QueryBuilder filterBuilder = null;

if (filterBuilders != null && filterBuilders.length > 0) {

  for(int i = 0 ; i < filterBuilders.length ; i++){
    filterBuilder = QueryBuilders.boolQuery().filter(filterBuilders[i]);
  }

}
return filterBuilder;

}

不，您要在每次迭代中创建一个新的bool/filter查询，并将其重新分配给相同的变量，但这种方法将不起作用。您需要这样做:

public static QueryBuilder andQuery(QueryBuilder... filterBuilders) {
  BoolQueryBuilder filterBuilder = null;

  if (filterBuilders != null && filterBuilders.length > 0) {
    // create the bool query here
    filterBuilder = QueryBuilders.boolQuery();    

    for(QueryBuilder filter : filterBuilders){
      // add each filter to the bool query here
      filterBuilder.filter(filter);
    }

  }
  return filterBuilder;
}
