[tor-commits] [onionoo/master] Support quoted qualified search terms.

[karsten@xxxxxxxxxxxxxx]

commit 75981fe7d03091c78f901e1589288be4a27ce56c
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

    Support quoted qualified search terms.
    
    With this patch, the "search" parameter does not only accept unquoted
    qualified search terms like `search=contact:John Doe` where "John"
    would be looked up in the contact line and "Doe" in the nickname or
    base64-encoded fingerprint. It also accepts quoted qualified search
    terms like `search=contact:"John Doe"` where "John Doe" would be
    looked up in the contact line. It further accepts escaped double
    quotes (\") within quoted qualified search terms.
    
    Implements #21366.
