Search issues with Secondary FAQ's when the secondary FAQ has whitespaces in the name

Escalation to an issue rather than a comment:

Thanks for all the great work on this extension.

With the new version I find that if I I create several FAQ's in subwikis then the search behaves as expected. This is what I do to create the other wikis.

1) Install the FAQ extension on the farm (which includes about six sub wikis).

2) Create several FAQ's on the main FAQ space to test.

3) Create a top level document (new space) and add FAQCode.FAQHomeClass.

4) Create some test FAQ's in this new space.

5) Copy FAQ.FAQSearch ** under the newly created space.

6) Search for something known to exist in the newly created FAQ space but not in the home FAQ.

7) Result is that on subwikis this works as expected - results are served from the FAQ collection in which the search page sits.

8) On the root wiki, secondary space FAQ's (in other spaces than the main wiki) no results are returned.

This may be a problem unique to my own wiki so my question is - could this be because there are old versions of the FAQ files hanging around on the root which are not present in sub wikis? If so, how might I search for and remove them? Or is this a remaining issue with the extension?

I have tried complete removal from the farm and re installation - same behaviour - fine on subwikis but not working on main wiki.

OK - just did some further testing.

I find that the search fails if the additional FAQ page has spaces in the name so - FAQ2.WebHome works fine but Medical FAQ.WebHome does not.

Does this work as an explanation?
