NAME
DBIx::Class::PhoneticSearch - Phonetic search with DBIC

SYNOPSIS
package MySchema::User;

use base 'DBIx::Class';

__PACKAGE__->load_components(qw(PhoneticSearch Core));

__PACKAGE__->table('user');

__PACKAGE__->add_columns(
id => { data_type => 'integer', auto_increment => 1, },
surname => { data_type => 'character varying',
phonetic_search => 1 },
forename => { data_type => 'character varying',
phonetic_search => { algorithm => 'Koeln',
no_indices => 1 } },

);

__PACKAGE__->set_primary_key('id');

__PACKAGE__->resultset_class('DBIx::Class::ResultSet::PhoneticSearch');

# somewhere else
$rs = $schema->resultset('User');
$rs->create({ forename => 'John', surname => 'Night' });

$rs->search_phonetic({ forename => 'Jon' })->first->forename; # John
$rs->search_phonetic({ surname => 'Knight' })->first->surname; # Night
$rs->search_phonetic({ forename => 'Jon',
surname => 'Knight' })->first->surname; # Night
$rs->search_phonetic([ surname => 'Smith' ,
surname => 'Knight' ])->first->surname; # Night (ORed)

DESCRIPTION
This components allows for phonetic search of columns. If you add the
`phonetic_search' attribute to a column, this component will add an
extra column to the result class which is basically an index of the
value based on its pronunciation. Every time the column is updated, the
phonetic column is set as well. It uses Text::Phonetic to compute the
phonetic representation of the value in that column. Use search_phonetic
to search for rows which sound similar to a given value.

The name of the phonetic column consists of the original column name and
the algorithm used:

$column + _phonetic_ + $algorithm

The above example will require two additional columns:

surname_phonetic_phonix character varying,
forename_phonetic_koeln character varying,

Make sure they exist in you database!

The default algorithm is Text::Phonetic::Phonix.

This component will also add indices for both the column and the
phonetic column. This can be disabled by setting no_indices.

To set the phonetic column on an already populated resultset use
update_phonetic_columns.

RESULTSET METHODS
search_phonetic
This method is used to search a resultset for a given set of
column/value pairs.

You can call this method with either an arrayref or hashref. Arrayref
will cause a query which will join the queries with `OR'. A hashref will
join them with an `AND'.

Returns a DBIx::Class::ResultSet.

update_phonetic_column
$rs->update_phonetic_column('columnname');

This method will update the phonetic column of a column.

update_phonetic_columns
Calls update_phonetic_column for each column with an phonetic column.

ADVANCED CONFIGURATION
algorithm
Choose one of `DaitchMokotoff DoubleMetaphone Koeln Metaphone Phonem
Phonix Soundex SoundexNara'.

See Text::Phonetic for more details.

Defaults to `Phonix'.

no_indices
By default this module will create indices on both the source column and
the phonetic column. Set this attribute to a true value to disable this
behaviour.

OVERWRITTEN RESULT METHODS
register_column
Set up the environment and add the phonetic columns.

store_column
Set the phonetic column to the encoded value.

sqlt_deploy_hook
This is where the indices are created.
