searchidx: use warn for excessively long terms

Filename and linenumber context information from Carp::carp is
unlikely to be useful here on (likely) worthless data from bad
MUAs.  carp adds needless noise for users tracking down actual
code bugs with PERL5OPT=-MCarp=verbose, which changes Carp::carp
into Carp::cluck.
