Symphony.

This problem has multiple levels

1. In the data source editor, I cannot use +. Doing a basic filter on a select box field for Cool + Hot gives no results, when entries do exist.
2. In the front end, if I use a form to pass URL params as Cool+Hot (encoded into ?param=Cool%2BHot, Symphony produces the param Cool Hot. I have to use ?param[]=Cool&param[]=Hot and use an event to hack it into a param Cool+Hot (but this still does not work, as per #1).

This may or may not be related to this problem with the Date Time field http://getsymphony.com/discuss/thread/83265/3/#position-49

Symphony 2.3.2 with PHP 5.4.4 on MAMP

I also have the same problem as described in this thread except that I used {$param1} + {$param2} instead of fixed names like Cool + Hot.

I found no solutions and my guess was that the DS "+" operator is broken. Hopefully someone comes up with something.

Definitely the same problem, except I don't get DB errors, just no result. Opened an issue: https://github.com/symphonycms/symphony-2/issues/1715

Please post any new findings on the bug tracker.
