I created a script (with the use of Zend's framework) last year which has been working fine, but suddenly today, it decided to misbehave.
The query searches for any calendar events with '[_]' in the title.
This has been working fine for the past year as I mentioned but suddently it doesn't like looking for those particular characters in such a specific phrase.
I checked the api was still working by using the same query but with a specified word in it, and it did retrieve relevant results.
Any one got any suggestions in order to make it look for those particular characters? Google have clearly changed something.
