如何使用Lucene API（a AND（b OR c））创建嵌套的布尔查询？

Question

我有一个带有三个字段（userId，标题，描述）的索引对象。我想找到标题或说明包含给定关键字的特定用户的所有对象。

我有这样的事情（但这显然是错误的）：

WildcardQuery nameQuery = new WildcardQuery(new Term("name", filter.getSearch()));
WildcardQuery descQuery = new WildcardQuery(new Term("description", filter.getSearch()));

TermQuery userQuery = new TermQuery(new Term("user_id", u.getId()+""));

BooleanQuery booleanQuery = new BooleanQuery();
booleanQuery.add(new BooleanClause(name_query, Occur.SHOULD));
booleanQuery.add(new BooleanClause(desc_query, Occur.SHOULD));
booleanQuery.add(new BooleanClause(user_query, Occur.MUST));

如何修改代码以获取具有正确ID和标题或描述中的搜索短语的所有对象？

Answer 1

我认为将是这样的：

TermQuery userQuery = new TermQuery(new Term("user_id", u.getId()+""));

BooleanQuery orQuery = new BooleanQuery();
orQuery.add(new BooleanClause(name_query, Occur.SHOULD));
orQuery.add(new BooleanClause(desc_query, Occur.SHOULD));

BooleanQuery andQuery = new BooleanQuery();
andQuery.add(new BooleanClause(userQuery , Occur.MUST));
andQuery.add(new BooleanClause(orQuery, Occur.MUST));
