Question

Hibernate：5.2.8.Final
Hibernate搜索：5.7.0.Final
配置：

FullTextEntityManager ftsEntityManager = Search.getFullTextEntityManager(entityManager);
        QueryBuilder queryBuilder = ftsEntityManager.getSearchFactory()
                .buildQueryBuilder().forEntity(Report.class).get();
        BooleanQuery.Builder builder = new BooleanQuery.Builder();
        BooleanQuery.Builder cmpBuilder = new BooleanQuery.Builder();
        companies.forEach(cmp -> cmpBuilder.add(
                NumericRangeQuery.newLongRange("merchant.company.company_id", cmp.getId(), cmp.getId(), true, true),
                BooleanClause.Occur.SHOULD));
        builder.add(cmpBuilder.build(), BooleanClause.Occur.MUST);
        builder.add(new TermQuery(new Term("status", status.name())), BooleanClause.Occur.MUST);
        org.apache.lucene.search.Query fromQuery = queryBuilder.range()
                .onField("createdAt")
                .above(from)
                .createQuery();
        org.apache.lucene.search.Query toQuery = queryBuilder.range()
                .onField("createdAt")
                .below(to)
                .createQuery();
        builder.add(fromQuery, BooleanClause.Occur.MUST);
        builder.add(toQuery, BooleanClause.Occur.MUST);           
        FullTextQuery fullTextQuery = ftsEntityManager.createFullTextQuery(builder.build(), Report.class);
        int results = fullTextQuery.getResultSize();
        EntityGraph graph = this.entityManager.getEntityGraph("Report.fetchMerchantAndAccount");
        List resultList = fullTextQuery
                .setFirstResult(pageable.getOffset())
                .setMaxResults(pageable.getPageSize())
                .setHint("javax.persistence.fetchgraph", graph)
                .getResultList();

我的代码：

2017-03-24 02:39:50.942 DEBUG 1984 --- [tp1560534902-96] org.hibernate.search.fulltext_query      : HSEARCH000274: Executing Lucene query '+(merchant.company.company_id:[2 TO 2]) +status:COMPLETE +createdAt:[0000020161102000000000000000 TO *] +createdAt:[* TO 0000020170324235959999999999]'

记录查询：

+(merchant.company.company_id:[2 TO 2]) +status:COMPLETE

我在Luke中测试了这个查询，效果很好：看起来这个参数{{1}}中的问题，但我无法弄清楚出了什么问题。

问题是我应该使用QueryBuilder而不是Lucene类。所以，改变这个：

companies.forEach(cmp -> cmpBuilder.add(
                NumericRangeQuery.newLongRange("merchant.company.company_id", cmp.getId(), cmp.getId(), true, true),
                BooleanClause.Occur.SHOULD));

到此：

companies.forEach(cmp -> cmpBuilder.add(queryBuilder.range().onField("merchant.company.company_id")
                .from(cmp.getId()).to(cmp.getId()).createQuery(), BooleanClause.Occur.SHOULD));

和此：

builder.add(new TermQuery(new Term("status", status.name())), BooleanClause.Occur.MUST);

到此：

builder.add(queryBuilder.keyword().onField("status").matching(status).createQuery(), BooleanClause.Occur.MUST);

解决了问题！

Hibernate使用工作查询搜索空结果
