*cough*

I can't reproduce this in 0.7.11, and looking at the code, I can't see how 
you're having a problem. The indexargs_url (also known as _href) code 
clearly quotes the values used in filtering.

Well, except for the full-text search field, but I just fixed that :)

The ";" in the date search field was definitely quoted for me (and checking 
urllib.quote() it definitely quotes ";"). What version of Python are you 
using?
