Hi there, I am stomped as to why QueryParser''s parse method behaves differently between query ''a'' and ''b''. See http://pastie.caboo.se/private/4rlwrecyyow3yl6qtf4tq Could someone please help me understand why that is the case. p.s. I also found ''i'' produce the same behavour as ''a'' Cheers, Andy
''a'' is a stop word by default (so is ''i'').
If you instantiate the query
parser with an Analyzer with no stop words, thusly:
qp3 = Ferret::QueryParser.new(
:analyzer => Ferret::Analysis::StandardAnalyzer.new([])
)
Then qp3.parse(''a'') (after the appropriate fields call) will
return the
desired results.

I also found ''i'' produce the same behavour as ''a''hey .. there is a concept called STOP_WORDS .. special words are simply ignored. The QueryParser will strip all STOP_WORDS. You should understand the way STOP_WORDS and QueryParsing works.. I would recommend: http://projects.jkraemer.net/acts_as_ferret/wiki/gotchas http://ferret.davebalmain.com/trac/wiki/FAQ%3AIndexing#HowdoIswitchofstop-wordremoval http://www.oreilly.com/catalog/9780596527853/index.html see also: ./script/console>> Ferret::Analysis::FULL_ENGLISH_STOP_WORDSBen
