A '@' special character is causing the community name to be searched as two terms. E.g. a name like XY@AB-CD is not found as a whole. The sign @ avoids that the whole phrase can be found (e.g. “XY@AB-CD”) or in a good ranking (result page 10 or more) as well as no fragments like AB-CD in a phrase like “XY@AB-CD” can´t be found in Connections.
The search in connections should be improved to be able to use special characters.

The problem is, the hashtags in comments are not recognised as hashtags, and could not be searched and found at all.
