The InvIndexer class is KinoSearch1's primary tool for creating and modifying inverted indexes, which may be searched using KinoSearch1::Searcher.
my $invindexer = KinoSearch1::InvIndexer->new(
invindex => '/path/to/invindex', # required
create => 1, # default: 0
analyzer => $analyzer, # default: no-op Analyzer
);
Create an InvIndexer object.
$invindexer->spec_field(
name => 'url', # required
boost => 1, # default: 1,
analyzer => undef, # default: analyzer spec'd in new()
indexed => 0, # default: 1
analyzed => 0, # default: 1
stored => 1, # default: 1
compressed => 0, # default: 0
vectorized => 0, # default: 1
);
Define a field.
my $doc = $invindexer->new_doc;
Spawn an empty KinoSearch1::Document::Doc object, primed to accept values for the fields spec'd by spec_field.
$invindexer->add_doc($doc);
Add a document to the invindex.
my $invindexer = KinoSearch1::InvIndexer->new(
invindex => $invindex,
analyzer => $analyzer,
);
$invindexer->add_invindexes( $another_invindex, $yet_another_invindex );
$invindexer->finish;
Absorb existing invindexes into this one. May only be called once per InvIndexer. add_invindexes() and add_doc() cannot be called on the same InvIndexer.
my $term = KinoSearch1::Index::Term->new( 'id', $unique_id );
$invindexer->delete_docs_by_term($term);
Mark any document which contains the supplied term as deleted, so that it will be excluded from search results. For more info, see Deletions in KinoSearch1::Docs::FileFormat.
$invindexer->finish(
optimize => 1, # default: 0
);
Finish the invindex. Invalidates the InvIndexer. Takes one hash-style parameter.
