Question:
How to retrieve all foos where foo.bar.id==1 using IFullTextQuery?

推荐答案

如果要将相关信息包含在foo索引中，则可以查看IndexedEmbeddedAttribute.这将允许您查询关系，例如在条对象上是否存在Name属性，您可以创建这样的查询

If you want to include related information into the foo index you may look into the IndexedEmbeddedAttribute. This will allow you to query for relationships such as if there was a Name property on the bar object you could create a query such as this

IFullTextQuery query = search.CreateFullTextQuery("bar.Name:Arnis");
query.List<foo>();
