Basically you should use the same analyzer to analyze queries as you
used to analyze your content. So constructing your queryparser like
this:
qp = QueryParser.new(:analyzer => Analysis::RegExpAnalyzer.new(/./, false))
your searches should work.
However, your regexp for the analyzer looks strange - /./ matches every
single character, including whitespace. So each field's value would be
indexed as 1-character long terms, which probably is not what you want.
However I don't know why searching through the Index class worked, I'd
suspect it not to work, too.
