I’ve also noticed the same problem for words other than “now” (see Fuzzy search forgets matches ). Is this a recent bug, or has it been happening for you for a while? I’ve been away from Workflowy for a while, but only noticed it recently.
So far I have only seen this in relation with time or date-related words.
I’m guessing that when specific words are recognized in the search (eg months or now), the search is handed to a different code path which does not care about exact matching
I have a tag #now and searches for that work ok, so maybe tags work around the date-words problem. Although I just tried to reproduce this bug with a search for “August” and it’s working for me at the moment. I wonder if they fixed it since my earlier post.
