|
| 41 |
=head2 new |
| 42 |
|
| 43 |
Open KinoSearch index |
| 44 |
|
| 45 |
my $out = new WebPAC::Output::KinoSearch({ |
| 46 |
path => '/path/to/invindex', |
| 47 |

encoding => 'iso-8859-2', |
| 49 |
clean => 1, |
| 50 |
}); |
| 51 |
|

Options are: |

|
| 54 |
=over 4 |
| 55 |
|
| 56 |
=item path |
| 57 |
|
| 58 |
path to KinoSearch index to use |
| 59 |
|
| 60 |
=item database |
| 61 |
|
| 62 |
name of database from which data comes |
| 63 |
|
| 64 |
=item encoding |
| 65 |
|
| 66 |
character encoding of C<data_structure> if it's differenet than C<ISO-8859-2> |
| 67 |
(and it probably is). This encoding will be converted to C<UTF-8> for |

index. |
