Question

试图找到范围查询的解决方案使用QueryBuilders.rangeQuery

问题： DateFrom可以为null或大于今天 DateTill可以为null或小于今天剩余的数量可以为null或值可以大于0

只有文档必须出现在我试图解决此问题的搜索结果中

         publishedFilter.should(QueryBuilders.boolQuery()
                .mustNot(QueryBuilders.existsQuery(SearchAble.QUANTITY_REMAINING)))
            .should(QueryBuilders.rangeQuery(SearchAble.QUANTITY_REMAINING).gte(1))
            .minimumShouldMatch(1);

        publishedFilter.should(QueryBuilders.boolQuery()
            .mustNot(QueryBuilders.existsQuery(SearchAble.DATE_TIME_FROM))
            .should(QueryBuilders.rangeQuery(SearchAble.DATE_TIME_FROM).lte(time))
        );

        publishedFilter.should(QueryBuilders.boolQuery()
            .mustNot(QueryBuilders.existsQuery(SearchAble.DATE_TIME_TILL))
            .should(QueryBuilders.rangeQuery(SearchAble.DATE_TIME_TILL).gte(time))
        );

但是此解决方案仅适用于剩余的数量而不是dateFrom和dateTill

有什么想法吗？

Answer 1

我会这样做：

    // at least one of the OR conditions must match
    publishedFilter.minimumShouldMatch(1);

    // OR condition for Quantity
    publishedFilter.should(QueryBuilders.boolQuery()
        .should(QueryBuilders.boolQuery().mustNot(QueryBuilders.existsQuery(SearchAble.QUANTITY_REMAINING)))
        .should(QueryBuilders.rangeQuery(SearchAble.QUANTITY_REMAINING).gte(1))
    );

    // OR condition for Date From
    publishedFilter.should(QueryBuilders.boolQuery()
        .should(QueryBuilders.boolQuery().mustNot(QueryBuilders.existsQuery(SearchAble.DATE_TIME_FROM)))
        .should(QueryBuilders.rangeQuery(SearchAble.DATE_TIME_FROM).lte(time))
    );

    // OR condition for Date Till
    publishedFilter.should(QueryBuilders.boolQuery()
        .should(QueryBuilders.boolQuery().mustNot(QueryBuilders.existsQuery(SearchAble. DATE_TIME_TILL)))
        .should(QueryBuilders.rangeQuery(SearchAble. DATE_TIME_TILL).gte(time))
    );

是的，这是个主意，但这种情况并未被要求接受，因为如果我有一个叫他的对象，searchDto必须在方案中可以搜索数据

 searchDto.setQuantityRemaining(0);

 searchDto.setQuantityRemaining(1);
        searchDto.setDateTimeRange(DateTimeRangeDto.builder()
            .dateTimeFrom(null)
            .dateTimeTill(null)
            .build());

        searchDto.setQuantityRemaining(null);
        searchDto.setDateTimeRange(DateTimeRangeDto.builder()
            .dateTimeFrom(null)
            .dateTimeTill(null)
            .build());

        searchDto.setQuantityRemaining(null);
        searchDto.setDateTimeRange(DateTimeRangeDto.builder()
            .dateTimeFrom(OffsetDateTime.now())
            .dateTimeTill(null)
            .build());

        searchDto.setQuantityRemaining(2);
        searchDto.setDateTimeRange(DateTimeRangeDto.builder()
            .dateTimeFrom(OffsetDateTime.now())
            .dateTimeTill(OffsetDateTime.now().plusHours(1))
            .build());



        // and not searchable

        searchDto.setQuantityRemaining(0);
        searchDto.setDateTimeRange(DateTimeRangeDto.builder()
            .dateTimeFrom(OffsetDateTime.now().plusHours(1))
            .dateTimeTill(OffsetDateTime.now())
            .build());

QueryBuilders rangeQuery具有空的日期或值
