Network error on search function, or search function not working on certain conditions

in Bugs
This happens on the website and on the Astiga phone app, but it shows differently.
Phone:
I tried to search for a song using the search function. This are two strings I tried to use in the search:
I also get this "error" response randomly when trying to search.
The search string: "my name on", provides my with the song I am searching for. The song is called "a bullet w- my name on"
On the Website it's different. I don't get an error. I just don't get any results. (when trying "a bullet")
Might it be due to the search string starting with one letter and a space after? I think it might also have do to with searching for a string or song I don't have in my library or cloud; which should return an empty page with no songs instead of an error.
Comments
We've recreated both of these issues - they are different.
The query with the slash is because we're not correctly escaping that character.
The query with just "a bullet" is because there's a bug where, if nothing matches, an error occurs. I guess the next problem is "why doesn't it match" but that's more likely to be something to do with the search algorithm, which we can look into later.
