With bin/51062, makemandb(8) can index non-numeric sections and also apropos(1) can now accept non-numeric sections for querying. That means you do queries like apropos -s 9lua systm apropos -s n foo bar To be able to use this feature, you need to regenerate the database. You can do this by running makemandb -f manually.
I rebuilt my database. Although apropos(1) now finds the information for the non-numeric sections, it is still reporting them wrongly:
# apropos -s 9lua lua intro (9) introduction to the Lua kernel bindings This section provides an overview of the Lua kernel bindings, ... Note that the output says "intro (9)" - shouldn't it say "intro (9lua)"? +------------------+--------------------------+------------------------+ | Paul Goyette | PGP Key fingerprint: | E-mail addresses: | | (Retired) | FA29 0E3B 35AF E8AE 6651 | paul at whooppee.com | | Kernel Developer | 0786 F758 55DE 53BA 7731 | pgoyette at netbsd.org | +------------------+--------------------------+------------------------+
