The developer working on Simplenote.app for OS X took an unfortunate shortcut when coding search. That’s kind of a problem, because search is what Simplenote is about.
It’s easy to see the problem.
In Simplenote 1.1 for OS X a note that has three words in it:
blue green yellow
search on blue and you’ll find the note. Search on blue green and you’ll find it. But search on [blue yellow] and you won’t.
That’s because the developer implemented a very simple string match search (sometimes this is called phrase search, but that’s a bit grandiose). Whatever string you enter in search has to directly match a string in the note.
Now repeat the same experiment with the Web version or Simplenote.app for iOS You’ll find that [blue yellow] works, as does [blu yell]. The developers who implemented search on iOS and the web used what I call ‘word-starts-with-search’; it means a separate index is created containing all the lexical tokens and the input tokens are boolean matched against the index tokens (see also).
I’m quite surprised the OS X app passed Automatic acceptance testing — search is feature #1 for this app and it’s very broken in the OS X version.
