Lucene has simple wildcard syntax supporting ? and * thus ruby could be
matched by rub? r*by etc.
This doesn’t work using rdig on the command line
e.g. rdig -c config.rb -q ‘data:“ru?y”’ gives
RDig version 0.3.4
using Ferret 0.10.14
executing query >data:“ru?y”<
Query: data:“ru y”~1
which is something entirely different. The ferret docs seem to imply
that support for wildcard works as in lucene though I haven’t tried it
yet
