Spring Data Elasticsearch 自定义检索字段比重，计算得分

　　　　　　　BoolQueryBuilder fuzzyQuery = QueryBuilders.boolQuery();
            String[] matchFieldNames = {"itemName", "categoryNames", "baseCategoryName", "materialNameAilas",
                "materialName", "supplierNames", "attributeNames", "attributeNamesAilas", "attributeValueNames"};
            MultiMatchQueryBuilder multiMatchQueryBuilder =
                QueryBuilders.multiMatchQuery(paramsDto.getFuzzyQuery(), matchFieldNames)
                    .type(MultiMatchQueryBuilder.Type.BEST_FIELDS);
            // 设置权重
            Map<String, Float> mfieldsBoosts = new HashMap<>();
            mfieldsBoosts.put("itemName", 11f);
            mfieldsBoosts.put("categoryNames", 6f);
            mfieldsBoosts.put("baseCategoryName", 5f);
            mfieldsBoosts.put("materialNameAilas", 9f);
            mfieldsBoosts.put("materialName", 10f);
            mfieldsBoosts.put("supplierNames", 4f);
            mfieldsBoosts.put("attributeNames", 8f);
            mfieldsBoosts.put("attributeNamesAilas", 7f);
            mfieldsBoosts.put("attributeValueNames", 3f);
            multiMatchQueryBuilder.fields(mfieldsBoosts);
            fuzzyQuery.should(multiMatchQueryBuilder)
                .should(QueryBuilders.wildcardQuery("itemSkuCodes", "*" + paramsDto.getFuzzyQuery() + "*"))
                .should(QueryBuilders.wildcardQuery("itemSkuModels", "*" + paramsDto.getFuzzyQuery() + "*"));
            filter.must(fuzzyQuery);

 

这样就可以根据字段权重计算得分，进行查询结果排序
