KSx::Search::WildCardQuery - Wild card query class for KinoSearch

0.05

    use KSx::Search::WildCardQuery
    my $query = new KSx::Search::WildCardQuery
        term  => 'foo*',
        field => 'content',
    ;

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

This module provides search query objects for KinoSearch that perform wild-card searches. Currently, asterisks (*) are the only wild cards supported. An asterisks represents zero or more characters. This is a subclass of KSx::Search::RegexpTermQuery (q.v.)|KSx::Search::RegexpTermQuery.

If a term begins with literal (non-wild-card) characters (e.g., the foo in foo*), 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., *foo*), the entire index will be scanned, so beware.

This is the constructor. It constructs. Call it with hash-style arguments as shown in the SYNOPSIS.
