NAME

KSx::Search::RegexpTermQuery - Regular expression term query class for KinoSearch

VERSION

0.05

SYNOPSIS

    use KSx::Search::RegexpTermQuery
    my $query = new KSx::Search::RegexpTermQuery
        regexp => qr/^foo/,
        field  => 'content',
    ;

    $searcher->hits($query);
    # etc.

DESCRIPTION

This module provides search query objects for KinoSearch that find terms that match a particular regular expression. Note that a query will only match a single term; it is not a regexp match against an entire field.

PERFORMANCE

If a regular expression has a fixed literal prefix anchored to the beginning of the string (e.g., the foo in qr/^foo[dl]$/), only the 'foo' words in the index will be scanned, so this should not be too slow, as long as the prefix is fairly long, or there are sufficiently few 'foo' words. If, however, there is no literal prefix (e.g., qr/foo/), the entire index will be scanned, so beware.

METHODS

new

This is the constructor. It constructs. Call it with hash-style arguments as shown in the "SYNOPSIS". The regexp can be a qr// thingy or a string.
