APROPOS(1)			   BSD General Commands Manual			       APROPOS(1)

NAME
     apropos -- search the complete content of all man pages

SYNOPSIS
     apropos [-123456789Ccp] [-n Number of results] [-S machine] [-s section] query

DESCRIPTION
     The apropos utility performs a full text search over the complete content of all man pages.
     It uses the FTS engine of Sqlite to perform the search.  The database is created with the
     help of makemandb(8) utility.

     This implementation of the apropos utility is more sophisticated than the classical version
     of apropos.  Like modern search applications, it uses advanced techniques like stemming and
     term weighting to rank the matching results in decreasing order of relevance.  By default
     apropos will only display the top 10 matches in the output.

     Quotes are optional for specifying multiword queries.

     It supports the following options:

     -1      Search only within section 1 manual pages.

     -2      Search only within section 2 manual pages.

     -3      Search only within section 3 manual pages.

     -4      Search only within section 4 manual pages.

     -5      Search only within section 5 manual pages.

     -6      Search only within section 6 manual pages.

     -7      Search only within section 7 manual pages.

     -8      Search only within section 8 manual pages.

     -9      Search only within section 9 manual pages.

     -C      Do not show the context of the match.

     -c      Do show the context of the match (default).

     -n      Output up to the specified number of search results.  The default limit is 10.

     -p      Display all matching results and pipe them through a pager (defaulting to more(1)).

     -S machine
	     Limit the search to the pages for the specified machine architecture.  By default
	     pages for all architectures are shown in the search results.

     -s section
	     Restrict the search to the specified section of the manual.  By default, pages from
	     all section are shown.  This option is for backwards compatibility with the classic
	     version of apropos, using it is equivalent to using the [123456789] options
	     directly.

FILES
     /var/db/man.db The Sqlite FTS database which contains an index of the manual pages.

SEE ALSO

HISTORY
     The apropos command appeared in 3.0BSD.  It was rewritten in NetBSD 6.0 to support full text
     search using Sqlite.
