Keywords containing digits

[dasymington]

I've imported all my documents into UR, but I've found I can't locate items that contain digits. For example, I want to search for all documents that contain P11D; I could do this in X1 but by default UR seems to exclude keywords with digits. I've now ticked the Keyword words containing digits Option on the Import tag, but I'm left with all my existing documents being unsearcheable in this way.

Is there any way to get UR to rebuild the keywords? I know you can do that with Synchronize, but you need to do it document by document and I've got about 5000. Is there a way to sync all the documents in UR?
