When copy-pasting tab-separated values from a spreadsheet to the search field (e.g.author [tab] title), the input gets correctly parsed as "author title" for the autocomplete suggestions as you type.

However, if you press "enter," the space between the two gets disregarded entirely, and no match is found for "authortitle".

Would it be possible to convert any empty [tab] to a [space] in the search field?

(I verified this behaviour on Safari and Chrome on Mac OS, both logged in and logged out.)

I'm attaching screenshots in case my explanation was unclear!
