Not keywording subject

[dasymington]

I have an info item with the subject Dundee Office XP Upgrade and I've discovered, after searching for it for ages, that the keywords list for the item does not contain either XP or Upgrade, yet neither word is an excluded keyword. The item is a text item that was typed direclty into UR.

I think something similar might account for several other items that I've been unable to find by searching.

Is there anything that can be done about this? For example, can I get UR to re-generate the keywords for all such items?
