I just noticed this and didn't find another post about it.
There seems to have been a change in how the tagged search filter works, and now my old bookmark, which consisted of around 34 tags, serves a blank result page with the text "Sorry, too many tags requested".
Okay, I also agree they're too much tags and the tag list could be refined. Taking into account that wildcard searches don't work around this limit, it well might be a bit too tight.
As a side note, questions with new activity still load through the WebSockets, and can be loaded properly. Why is it not possible to filter by those tags initially but the WebSockets load through them properly? Is this intended behavior?
Edit: The search seems to be limited to 25 tags now. The character limit on the search textfield doesn't seem to have anything to do with it (example). Anyway, using wildcards on the search doesn't work around this either. For instance, searching for
[java*] or [visual*] also returns "Sorry, too many tags requested".
Can we raise the 25 tag limit ?
