如何在 Solr 中进行 IN 查询? [英] How to do an IN query in Solr?

问题描述

我有一个多值字段sharedTo"的文档，其中包含文档共享到的组.现在我想找到至少与给定组列表中的一个共享的所有文档.例如.我想找到共享给组foo"或组bar"或两者的所有文档.目前我正在构建这样的查询:

i'm having documents with a multivalued field "sharedTo" which contains the groups that the document is shared to. Now I want to find all documents that are shared to at least one of a list of given groups. E.g. I want to find all documents that are shared to the group "foo" or the group "bar" or both. Currently I'm building a query like this:

sharedTo:"foo" OR sharedTo:"bar"

对于每个组，我只添加一个新的 OR 查询部分.这是有效的，但是我想知道是否有更有效的方法来做到这一点

For each group I just add a new OR query part. This works, however I wonder if there is a more efficient way of doing this like a

sharedTo IN ('foo', 'bar')

推荐答案

如果您的默认运算符是 OR，那么您可以将查询设为

if your default operator is OR, then you can just give the query as

sharedTo:('foo' 'bar')

如果您的默认运算符是 AND，那么您必须这样做:sharedTo:(foo OR bar)

If your default operator is AND, then you'll have to do it like this: sharedTo:(foo OR bar)
