NAME

KinoSearch::Simple - Basic search engine.

SYNOPSIS

First, build an index of your documents.

    my $index = KinoSearch::Simple->new(
        path     => '/path/to/index/'
        language => 'en',
    );

    while ( my ( $title, $content ) = each %source_docs ) {
        $index->add_doc({
            title    => $title,
            content  => $content,
        });
    }

Later, search the index.

    my $total_hits = $index->search( 
        query      => $query_string,
        offset     => 0,
        num_wanted => 10,
    );

    print "Total hits: $total_hits\n";
    while ( my $hit = $index->fetch_hit_hashref ) {
        print "$hit->{title}\n",
    }

DESCRIPTION

KinoSearch::Simple is a stripped-down interface for the KinoSearch search engine library.

METHODS

new

    my $index = KinoSearch::Simple->new(
        path     => '/path/to/index/',
        language => 'en',
    );

Create a KinoSearch::Simple object, which can be used for both indexing and searching. Two hash-style parameters are required.

• path - Where the index directory should be located. If no index is found at the specified location, one will be created.

• language - The language of the documents in your collection, indicated by a two-letter ISO code. 12 languages are supported:

      |-----------------------|
      | Language   | ISO code |
      |-----------------------|
      | Danish     | da       |
      | Dutch      | nl       |
      | English    | en       |
      | Finnish    | fi       |
      | French     | fr       |
      | German     | de       |
      | Italian    | it       |
      | Norwegian  | no       |
      | Portuguese | pt       |
      | Spanish    | es       |
      | Swedish    | sv       |
      | Russian    | ru       |
      |-----------------------|

add_doc

    $index->add_doc({
        location => $url,
        title    => $title,
        content  => $content,
    });

Add a document to the index. The document must be supplied as a hashref, with field names as keys and content as values.

search

    my $total_hits = $index->search( 
        query      => $query_string,    # required
        offset     => 40,               # default 0
        num_wanted => 20,               # default 10
    );

Search the index. Returns the total number of documents which match the query. (This number is unlikely to match num_wanted.)

• query - A search query string.

• offset - The number of most-relevant hits to discard, typically used when "paging" through hits N at a time. Setting offset to 20 and num_wanted to 10 retrieves hits 21-30, assuming that 30 hits can be found.

• num_wanted - The number of hits you would like to see after offset is taken into account.

BUGS

Not thread-safe.
