NotQueryBuilder弹性搜索2.4执行模式 [英] NotQueryBuilder elasticsearch 2.4 execution modes

问题描述

弹性搜索中的.execution（和）的替代方法是什么？它的使用究竟是什么 -

  NotFilterBuilder excVariantsFilter = FilterBuilders.notFilter（FilterBuilders.termsFilter（products，productIds.toArray ）.execution（ 和））; 
  

解决方案

过滤器和查询已合并到ES 2.0和执行模式仅在过滤器上下文中有用，因此执行参数不再需要c>条款查询。

所以如果你想要一个等同的行为这个

  NotFilterBuilder excVariantsFilter = FilterBuilders.notFilter（FilterBuilders.termsFilter（products，productIds.toArray（））。execution（and））; 
  

你现在可以这样写：

  BoolQueryBuilder excVariantsFilter = QueryBuilders.boolQuery（）; 
 for（String productId：productIds.toArray（））{
 excVariantsFilter.mustNot（QueryBuilders.termQuery（products，productId））; 
} 
  

它将生成一个 bool / must_not 查询包含术语查询每个 productId ，相当于之前的 过滤器包含条款查询与 和执行模式

what is the alternative for .execution("and") in elastic search 2.4? and what exactly its usage –

 NotFilterBuilder excVariantsFilter = FilterBuilders.notFilter(FilterBuilders.termsFilter("products", productIds.toArray()).execution("and"));

解决方案

Filters and queries have been merged in ES 2.0 and the execution mode was only useful in a filter context, so there's no need anymore for that execution parameter in terms queries.

So if you want an equivalent behavior to this

NotFilterBuilder excVariantsFilter = FilterBuilders.notFilter(FilterBuilders.termsFilter("products", productIds.toArray()).execution("and"));

you can now write it like this:

BoolQueryBuilder excVariantsFilter = QueryBuilders.boolQuery();
for (String productId : productIds.toArray()) {
    excVariantsFilter.mustNot(QueryBuilders.termQuery("products", productId));
}

It will produce a bool/must_not query containing a term query for each productId, which is equivalent to the previous not filter containing a terms query with and execution mode
