Well, a more structured file would help pick the right tool. While awk has more built in orientation toward delimited fields and can work spanning lines with alternate separators, sed is fast and simple, with skills that are very easy to reuse on a wide variety of problems and that work interactively in vi at the :, and here, the separtors here are negative: not-escaped line feeds.

locate
LOCATE(1) BSD General Commands Manual LOCATE(1)
NAME
locate -- find files
SYNOPSIS
locate [-d dbpath] pattern
DESCRIPTION
locate searches a database for all pathnames which match the specified pattern. The database is recomputed periodically, and contains the
pathnames of all files which are publicly accessible.
Shell globbing and quoting characters (``*'', ``?'', ``'', ``['' and ``]'') may be used in pattern, although they will have to be escaped
from the shell. Preceding any character with a backslash (``'') eliminates any special meaning which it may have. The matching differs in
that no characters must be matched explicitly, including slashes (``/'').
As a special case, a pattern containing no globbing characters (``foo'') is matched as though it were ``*foo*''.
Options:
-d dbpath
Sets the list of databases to search to dbpath which can name one or more database files separated by ``:'', an empty component in the
list represents the default database. The environment variable LOCATE_PATH has the same effect.
EXIT STATUS
locate exits with a 0 if a match is found, and >0 if no match is found or if another problem (such as a missing or corrupted database file)
is encountered.
FILES
/var/db/locate.database Default database
/usr/libexec/locate.updatedb Script to update database.
