[lucy-user] field:term searching

[goran kent <go...@gmail.com>]

Hi,

I'm getting confusing results from searching for field:term - eg, if I
have a spec'd field "title" which is indexed, and I want to search
using title:bob, I would expect it to restrict searching in that
field.

I'm not getting *any* hits on this kind of search - I had a look in
the docs but nothing jumps out at me:  is there something special that
must be done to achieve this?

Thanks

Thanks!  That works perfectly and consistently.

parse $query with a QueryParser first, then pass the returned Query object to
$poly_searcher.

[resending to list after my reply-to-peter-only]

Thanks for the quick response, Peter.  Your suggestion sounds like the
solution, but I have no idea how to access that little nugget.  I'm
using PolySearcher:

...
my $poly_searcher = Lucy::Search::PolySearcher->new(
   schema    => $schema,
   searchers => \@searcher,
);

my $sort_spec =
 Lucy::Search::SortSpec->new( rules =>
     [ Lucy::Search::SortRule->new( field => ...

my $hits = $poly_searcher->hits(
   query      => $query,     # $query is the query string itself
   sort_spec  => $sort_spec,
   offset     => 0,
   num_wanted => 10,
);

How on earth do I get to QueryParser's methods from here?

Any pointers would be appreciated.

without seeing your code, it's hard to say. but have you set_heed_colons() ?
