[lucy-issues] [jira] [Commented] (LUCY-299) Using Blob field type stops search working on other fields

Nick Wellnhofer commented on LUCY-299:
--------------------------------------

I couldn't reproduce the issue with the following Perl script, tested under 0.4.4 and 0.5.0. I tried to replicate the schema you described but maybe there's something missing. Could you provide a minimal, self-contained test case?

{noformat}
#!/usr/bin/perl
use strict;
use warnings;

use Lucy;

my $schema = Lucy::Plan::Schema->new;
my $easyanalyzer = Lucy::Analysis::EasyAnalyzer->new(
    language => 'en',
);
my $type = Lucy::Plan::FullTextType->new(
    analyzer => $easyanalyzer,
);
$schema->spec_field( name => 'title',   type => $type );
my $blob_type = Lucy::Plan::BlobType->new( stored => 1 );
$schema->spec_field( name => 'content', type => $blob_type );

my $indexer = Lucy::Index::Indexer->new(
    schema   => $schema,
    index    => 'index',
    create   => 1,
    truncate => 1,
);
$indexer->add_doc({
    title   => 'abc',
    content => 'def',
});

$indexer->commit;

my $searcher = Lucy::Search::IndexSearcher->new(
    index => 'index'
);

print("String search\n");
search('abc');

print("TermQuery search\n");
search(
    Lucy::Search::TermQuery->new(
        field => 'title',
        term  => 'abc',
    ),
);

sub search {
    my $query = shift;

    my $hits = $searcher->hits( query => $query );
    while ( my $hit = $hits->next ) {
        print "$hit->{title}: $hit->{content}\n";
    }
}

> Running into an apparent issue using BlobType_new to create FieldType.
> Scenario:
> Creating a schema with two fields, "fullpath" and "title". Using EasyAnalyzer.
> Add a couple of entries to the index
> Issued a search against the index
> Problem: If for fullpath field I use BlobType_new for FieldType, no search match is found. However, if I use either FullTextType_new or StringType_new for the schema FieldType of fullpath, it works fine.
> If I do not add fullpath at all, not to schema nor of course with Doc_Store - i.e. just have a single field of title - my scenario works fine (get a search hit). 
> If I add fullpath to the schema, but not to the doc entries (via Doc_Store), it works fine (get a search hit).
> It makes no difference (still get no match) if add fullpath before or after title.
> It makes no difference (still get no match) whether I pass true or false as parm to BlobType_new.
> In all cases, FieldType for title is fulltext; and it is title that is generating the matches against the search query.
