That error makes no sense to me.
In the relevant section of code, BooleanQuery is iterating over its
subclauses, extracting their Query objects, and calling a method on
them. (The method happens to be create_weight(), but that doesn't
matter.) In this case, there should be two subclauses, one for 'foo'
and one for 'bar'. Each should have a TermQuery in it.
Either one of those TermQuery objects has mysteriously transformed
into an undef, or there's an extra mystery clause with an undef.
I've never seen either of those things happen. If the query string
were something esoteric, I'd suspect a bug in QueryParser, but 'foo
bar' shouldn't be misbehaving.
The strange thing is that if your install was borked, I'd expect
stuff to fail long before we get to that point. And we haven't even
gotten into the C code -- Searcher, QueryParser, and all the Query
classes are pure Perl in 0.14.
I'd be surprised if KinoSearch can pass its test suite if something
like this is going on. Grab a copy of 0.14 from <http://
www.rectangular.com/downloads/KinoSearch-0.14.tar.gz>, decompress it,
cd into the t/ directory and start running test files:
... and so on. Do they work?
