The character set used for the markdown output is ASCII.

these contexts.

The query is built using the following grammar:
.Bd -literal -offset indent
<query> ::= "SELECT * FROM mpages WHERE" <condition>
<condition> ::= "(" <condition> ")" |
<condition> "OR" <condition> |
<condition> "AND" <condition> |
"desc" <operator> "?" |
"id IN (SELECT pageid FROM" <subquery> ")"
<subquery> ::= "names WHERE name" <operator> "?" |
"keys WHERE key" <operator> "? AND bits & ?"
<operator> ::= "MATCH" | "REGEXP"
.Ed
.Pp
The MATCH and REGEXP operators are implemented by the functions
.Fn sql_match
and
.Fn sql_regexp ,
respectively.
This is required because SQLite3 natively neither supports
case-insensitive substring matching nor regular expression matching,
but only string identity, shell globbing, and the weird home-brewed
LIKE operator.
.Pp
Command line parsing is done by the function
.Fn exprcomp
building a singly linked list of
.Vt expr
structures, using the helper functions
.Fn exprterm
.Fn expr_and
and
.Fn exprspec .
The resulting SQL statement is assembled by the function
.Fn sql_statement
and evaluated in the main loop of the
.Fn mansearch
function.
.Fn exprterm .
.Ss Assembling the results
The names, sections, and architectures of the manuals found
are assembled into the
.Va names
field of the result structure by the function
.Fn buildnames ,
using the following query:
.Pp
.Dl "SELECT * FROM mlinks WHERE pageid=? ORDER BY sec, arch, name"
.Pp
If the
.Fa outkey
differs from
.Qq Ic \&Nd ,
the requested output data is assembled into the
.Va output
field of the result structure by the function
.Fn buildoutput ,
using the following query:
.Pp
.Dl "SELECT * FROM keys WHERE pageid=? AND bits & ?"
.Fn buildnames .
.Sh FILES
.Bl -tag -width mandoc.db -compact
.It Pa mandoc.db
The manual page database.
.El
.Sh EXAMPLES
The simplest invocation
.Pp
.Dl apropos keyword
.Pp
results in the following SQL query:
.Bd -literal
SELECT * FROM mpages WHERE (
id IN (SELECT pageid FROM names WHERE name MATCH 'keyword') OR
desc MATCH 'keyword'
);
.Ed
.Pp
A more complicated request like
.Pp
.Dl apropos -s 2 Nm,Xr=getuid
.Pp
results in:
.Bd -literal
SELECT * FROM mpages WHERE (
id IN (SELECT pageid FROM names WHERE name MATCH 'getuid') OR
id IN (SELECT pageid FROM keys WHERE key MATCH 'getuid' AND bits & 4)
) AND id IN (SELECT pageid FROM keys WHERE key REGEXP '^2$' AND bits & 2);
