\&\f(CW\*(C`Perldoc::Search\*(C'\fR uses the swish-e engine to index the local Perl
documentation. It provides both the command line utility \f(CW\*(C`perldig\*(C'\fR
and an \s-1API\s0 to perform searches on the index. It uses \f(CW\*(C`SWISH::API::Common\*(C'\fR 
as the indexing and search engine.
.PP
Most likely, you will want the command line utility \f(CW\*(C`perldig\*(C'\fR, please
check the documentation that comes with it by calling
