new¶

    my $invindexer = KinoSearch1::InvIndexer->new(
        invindex => '/path/to/invindex',  # required
        create   => 1,                    # default: 0
        analyzer => $analyzer,            # default: no-op Analyzer
    );

Create an InvIndexer object.

• invindex - can be either a filepath, or an InvIndex subclass such as KinoSearch1::Store::FSInvIndex or KinoSearch1::Store::RAMInvIndex.
• create - create a new invindex, clobbering an existing one if necessary.
• analyzer - an object which subclasses KinoSearch1::Analysis::Analyzer, such as a PolyAnalyzer.

spec_field¶

    $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.

• name - the field's name.
• boost - A multiplier which determines how much a field contributes to a document's score.
• analyzer - By default, all indexed fields are analyzed using the analyzer that was supplied to new(). Supplying an alternate for a given field overrides the primary analyzer.
• indexed - index the field, so that it can be searched later.
• analyzed - analyze the field, using the relevant Analyzer. Fields such as "category" or "product_number" might be indexed but not analyzed.
• stored - store the field, so that it can be retrieved when the document turns up in a search.
• compressed - compress the stored field, using the zlib compression algorithm.
• vectorized - store the field's "term vectors", which are required by KinoSearch1::Highlight::Highlighter for excerpt selection and search term highlighting.

new_doc¶

    my $doc = $invindexer->new_doc;

Spawn an empty KinoSearch1::Document::Doc object, primed to accept values for the fields spec'd by spec_field.

add_doc¶

    $invindexer->add_doc($doc);

Add a document to the invindex.

add_invindexes¶

    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.

delete_docs_by_term¶

    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.

finish¶

    $invindexer->finish( 
        optimize => 1, # default: 0
    );

Finish the invindex. Invalidates the InvIndexer. Takes one hash-style parameter.

•

optimize - If optimize is set to 1, the invindex will be collapsed to its most compact form, which will yield the fastest queries.
