对多值字段计数进行操作的 Solr 函数查询 [英] Solr function query that operates on count of multivalued field

问题描述

我可以在 Solr 函数查询中计算多值字段中值的数量吗?我将如何编写函数查询来返回具有特定字段的 3 个或更多值的文档?

Can I, within a Solr function query, count the number of values in a multivalued field? How would I write a function query that returns documents with, say, 3 or more values for a particular field?

推荐答案

这里是函数查询参考，而且它没有列出类似的东西，所以我认为可以安全地假设没有这样的东西.

Here's the function query reference, and it doesn't list anything like that, so I think it's safe to assume that there's no such thing.

如果值计数与您的情况有某种关系，请将其添加为单独的 int 字段，然后对该字段进行操作.

If the value count is somehow relevant in your case, add it as a separate int field, then operate on that field.
