search all messages, not separate groups
Fragment of a discussion from Support/LiquidThreads
I'm not sure what search you're using, but Special:Search and Special:SearchTranslations return results immediately for me.
The message is MediaWiki:Histlegend/hr You won't find that message with that specific string, because it's a local customisation: w:hr:MediaWiki:Histlegend.
@Nemo: my bad, what I was using is the list *filter* (upper right corner of the table here), which I suppose is fetching data from the server as it filters them. Special:SearchTranslations definitely helps for these hard-to-find messages, but for general use it lacks the comfort of being able to see and edit related messages without ever leaving the translation tool (Special:Translate) page. Thanks!
