Consider an example directory containing:
If I want to find the pdf, and happen to remember that it had "numKK" in the filename, I might reasonably search "numKK" and expect to find it. In practice though, this will return 0 results. A search for *numKK will return the pdf though. Okay, so maybe there's something weird going on having a "-" in the filename, those images should be very searchable though. I remember that I liked image 209, so let me search "209". Weird, no results. But I know it was there, how about "*209"? Or "*209*"? Neither returns results. I need to search "0209" to find that image.
This is just a quick example, but in retrospect I'm certain there are other problematic filename/search combos that seem like they should really work but don't. I only found out about both of these behaviors recently. Are there any other search query quirks I should be aware of? And why are there such basic shortcomings in the current implementation of the search feature?
Directory was indexed in case that question arises.
