Sort optional fields in Lucene.net

I have a Lucene index which:

I have a requirement to sort search results by Title and Tag fields. At the moment, if none of the documents in the index contain Tag field, the search throws an SystemException: "field "Tag" does not appear to be indexed".

I am aware this behaviour is by design.
Is there a way to tell Lucene to optionally sort by Tag field if it exists?

What I'd do here is add another field that is concatenated title and tags and then sort by that -- should get you what you want and you'll still be able to ride the lucene rails.

No. You have to implement a custom sort on the search results
