SYNOPSIS
Attempt to find matching theorems in the currently loaded theories.
DESCRIPTION
An invocation DB.apropos M collects all theorems, definitions, and axioms of the currently loaded theories that have a subterm that matches M. If there are no matches, the empty list is returned.

Never fails.

COMMENTS
The notion of matching is a restricted version of higher-order matching.

For finer control over the theories searched, use DB.match.
