When I click on the forum’s Search button, there used to be a checkbox labeled 'Search [current category name]. Un-checking this box would allow searching the entire forum without backing out to the top.
This checkbox has been replaced with a redundant button to search the current forum:
This is getting confusing. Sometimes those options appear, and sometimes they don’t, and I can’t figure out when or why.
Additionally, when those options don’t appear, there’s no way to get to past the dropdown search results without selecting one. In the past, pressing Enter would do this. Now, Enter just refreshes the dropdown.
After a few weeks of trying to get used to the new search, I’ve come to the conclusion that it is a big step backwards from the old search. Please give feedback to Discourse asking them to undo these changes.
