我需要应用一个“OR”过滤器，它相当于（'a' or 'b' or 'c' or 'd' or 'e'）中的类别，下面提供了一个等效的 ES 查询 

"query_string": {
                      "query": "category: (\"a\", \"b\", \"c\", \"d\", \"e\")"
                   }

我有下面提到的 JAVA ES API 代码，我对在 Java 中添加 OR 过滤器感到震惊。有人可以帮忙吗？

SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder()
     searchSourceBuilder.query(QueryBuilders.boolQuery()
                .must(QueryBuilders.filteredQuery(QueryBuilders.matchAllQuery(),
                        FilterBuilders.termFilter("category","a")))
                .must(QueryBuilders.rangeQuery("@timestamp").from(fromHr).to(toHr)))
                .fields(fieldList);

根据您的示例，我假设您使用的是 ES 1.x 并假设 RangeQuery 应该是一个查询。如果我正确理解你的问题，你想做这样的事情：

QueryBuilders.filteredQuery(
 QueryBuilders.rangeQuery("@timestamp").from(fromHr).to(toHr),
 FilterBuilders.boolFilter()
  .should(FilterBuilders.termFilter("category","a"))
  .should(FilterBuilders.termFilter("category","b")) 
  .should(FilterBuilders.termFilter("category","c")) 
  .should(FilterBuilders.termFilter("category","d"))   
  .should(FilterBuilders.termFilter("category","e"))
)

但是，您也可以使用术语过滤器：

QueryBuilders.filteredQuery(
  QueryBuilders.rangeQuery("@timestamp").from(fromHr).to(toHr),
  FilterBuilders.termsFilter("category", "a", "b", "c", "d", "e", "f" ))
