The list of functions returned can be customized based on the pattern.

----
include-tagged::{sql-specs}/docs.csv-spec[showFunctionsLikeExact]
----
A wildcard for exactly one character:
["source","sql",subs="attributes,callouts,macros"]
----
include-tagged::{sql-specs}/docs.csv-spec[showFunctionsLikeChar]
----
A wildcard matching zero or more characters:
["source","sql",subs="attributes,callouts,macros"]
----
include-tagged::{sql-specs}/docs.csv-spec[showFunctionsLikeWildcard]
----
Or of course, a variation of the above:
