【问题描述】：

我通过网址卖家和猫喜欢：

sellers=1,2,3,4,5&cats=6,7,8,9

我将其拆分为方法并尝试将条件添加到弹性：

Optional.ofNullable(searchParams.getSellers().split(",")).ifPresent(v -> 
            filters.add(boolFilter().must(termFilter("seller", v)));
        );

    Optional.ofNullable(searchParams.getCats().split(",")).ifPresent(v -> 
        filters.add(boolFilter().must(termFilter("cat", v)));
    );

但结果不是我所期望的。它仅按最后一个卖家和最后一个类别查找。我想通过 URL 中的所有特定过滤器进行搜索。任何想法我应该怎么做？

public FacetedPage<TransIndex> searchByIndexParams(TransIndexSearchParams searchParams, Pageable pageable) 
        final List<FilterBuilder> filters = Lists.newArrayList();
        final NativeSearchQueryBuilder searchQuery = new NativeSearchQueryBuilder().withQuery(matchAllQuery());

        Optional.ofNullable(searchParams.getBuyer()).ifPresent(v -> filters.add(boolFilter().must(termFilter("buyer", v))));
        Optional.ofNullable(searchParams.getCat()).ifPresent(v -> filters.add(boolFilter().must(termFilter("cat", v))));
        Optional.ofNullable(searchParams.getComment_type()).ifPresent(v -> filters.add(boolFilter().must(termFilter("comment_type", v))));
        Optional.ofNullable(searchParams.getItem()).ifPresent(v -> filters.add(boolFilter().must(termFilter("item", v))));
        Optional.ofNullable(searchParams.getSeller()).ifPresent(v -> filters.add(boolFilter().must(termFilter("seller", v))));
        Optional.ofNullable(searchParams.getTree_cat()).ifPresent(v -> filters.add(boolFilter().must(termFilter("tree_cat", v))));

        final BoolQueryBuilder boolQueryBuilder = new BoolQueryBuilder();


        if(searchParams.getSellers() != null)
            Optional.ofNullable(searchParams.getSellers().split(",")).ifPresent(v -> 
                filters.add(boolFilter().must(termFilter("seller", v)));
            );
        



        if(searchParams.getCats() != null)
            Optional.ofNullable(searchParams.getCats().split(",")).ifPresent(v -> 
                filters.add(boolFilter().must(termFilter("cat", v)));
            );
        


        if (Optional.ofNullable(searchParams.getTitle()).isPresent()) 
            boolQueryBuilder.should(queryStringQuery(searchParams.getTitle()).analyzeWildcard(true).field("title"));
        

        if (Optional.ofNullable(searchParams.getComment_text()).isPresent()) 
            boolQueryBuilder.should(queryStringQuery(searchParams.getComment_text()).analyzeWildcard(true).field("comment_text"));
        

        if (Optional.ofNullable(searchParams.getPriceFrom()).isPresent()
                && Optional.ofNullable(searchParams.getPriceTo()).isPresent()) 
            filters.add(rangeFilter("price").from(searchParams.getPriceFrom()).to(searchParams.getPriceTo()));
        

        if (Optional.ofNullable(searchParams.getTsFrom()).isPresent()
                && Optional.ofNullable(searchParams.getTsTo()).isPresent()) 
            filters.add(rangeFilter("ts").from(searchParams.getTsFrom()).to(searchParams.getTsTo()));
        

        searchQuery.withPageable(pageable);
        searchQuery.withQuery(boolQueryBuilder);
        FilterBuilder[] filterArr = new FilterBuilder[filters.size()];
        filterArr = filters.toArray(filterArr);

        searchQuery.withFilter(andFilter(filterArr));

        final FacetedPage<TransIndex> response = transactionIndexRepository.search(searchQuery.build())



        return response;
    

如果我尝试转储过滤器，它看起来像：

System.out.println(filters);

[
  "bool" : 
    "must" : 
      "term" : 
        "seller" : [ "1", "2", "3", "4", "5" ]
      
    
  
, 
  "bool" : 
    "must" : 
      "term" : 
        "cat" : [ "6", "7", "8', "9" ]
      
    
  
]

【问题讨论】：

尝试使用termsFilter()而不是termFilter()

我认为现在很好，谢谢。

【参考方案1】：

您需要使用termsFilter() 而不是termFilter()
