休眠搜索中的 OnFields 方法接受什么数据类型

Question

我希望能够使用休眠搜索仅搜索用户在表单中选择的字段。

例如，如果用户选择按名字搜索，hibernate 应该只考虑名字。如果用户选择名字和姓氏，hibernate 应该考虑名字和姓氏。

 FullTextEntityManager fullTextEntityManager =
                org.hibernate.search.jpa.Search.
                        getFullTextEntityManager(entityManager);

        QueryBuilder queryBuilder =
                fullTextEntityManager.getSearchFactory()
                        .buildQueryBuilder().forEntity(Client.class).get();

        org.apache.lucene.search.Query query =
                queryBuilder
                        .keyword()
                        .wildcard()
                        // i want below section (fields) to change based on user input but can't do it with list<string> or collection
                        .onFields("idNumber", "firstName", "middleName","lastName","nationality")
                        .matching("*"+searchText.toLowerCase()+"*")
                        .createQuery();

Answer 1

使用List.toArray:

List<String> fieldsSelectedByUser = ...;
 FullTextEntityManager fullTextEntityManager =
                org.hibernate.search.jpa.Search.
                        getFullTextEntityManager(entityManager);

        QueryBuilder queryBuilder =
                fullTextEntityManager.getSearchFactory()
                        .buildQueryBuilder().forEntity(Client.class).get();

        org.apache.lucene.search.Query query =
                queryBuilder
                        .keyword()
                        .wildcard()
                        .onFields(fieldsSelectedByUser.toArray(new String[0]))
                        .matching("*"+searchText.toLowerCase()+"*")
                        .createQuery();
