The search is case insensitive and matches whole words only.

In this mode, macro keys, comparison operators, and logical operators

are not available.

Use the colon-separated path instead of the default list of paths

searched for

databases.

Invalid paths, or paths without manual databases, are ignored.

.It Fl m Ar path

Prepend the colon-separated paths to the list of paths searched
