apropos -- search the complete content of all man pages
apropos [-123456789Ccp] [-n Number of results] [-S machine] [-s section]
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)).
Limit the search to the pages for the specified machine architec-
ture. By default pages for all architectures are shown in the
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  options directly.
