The pictures says it all: Pi doesn’t show up on search. Jokes aside, it’s not that of a big problem. I could rename the tiddler to “Mathematical Constant Pi” but now there’s a problem with freelinks, that is, I couldn’t see the tiddlers that referred to it implicitly (i.e. without [[linking]]).
I bet that including two letter words to show up on search would require more resources as there will be a lot of unnecessary results.
So how do you guys make Pi discoverable on the search box?
A recent trick shared with me is follow it with a space. Once the search starts it looks for words anyway. I have created a tool that pops up in the Too short message if you want. You can do the same for symbols eg $$<space>
