SWISH::PlusPlus - Perl extension for full-text indexer SWISH++ with properties support |

=head1 SYNOPSIS |
20 |
|
21 |
use SWISH::PlusPlus; |
22 |
|
23 |
my $i = new SWISH::PlusPlus( |
24 |
index_dir => '/tmp/foo', |
25 |
); |
26 |
$i->add( 42 => 'meaning of life' ); |
27 |
|
28 |
print $i->search("meaning"); # returns 42 |

=head1 DESCRIPTION |
31 |
|
32 |
This is perl module to use SWISH++ indexer by Paul J. Lucas. SWISH++ is |
33 |
rewrite of swish-e in C++ which is extremely fast (due to mmap usage and |
34 |
clever language heuristics), but without support for properties (which this |
35 |
module tries to fix). |
36 |
|
37 |
Implementation of API is something in-between C<SWISH::API> and |
38 |
C<Plucene::Simple>. It should be easy to replace Plucene or swish-e with |
39 |
this module for increased performance. However, this module is not plug-in |
40 |
replacement. |
41 |
|
42 |
=head1 METHODS |
43 |
|
44 |
=head2 new |
45 |
|
46 |
Create new instance for index. |
47 |
|
48 |
my $i = SWISH::PlusPlus->new( |
49 |
index_dir => '/path/to/index', |
50 |
index => 'index++', |
51 |
search => 'search++', |
52 |
debug => 1, |
53 |
meta_in_body => 1, |
54 |
use_stopwords => 1, |
55 |
); |
56 |
|
57 |
Options are described below: |
58 |
|
59 |
=over 5 |
60 |
|
61 |
=item C<index_dir> |
62 |
|
63 |
Path to directory in which index and meta database will be created. |
64 |
|
65 |
=item C<index> |
66 |
|
67 |
Full or partial path to SWISH++ index executable. By default, it's B<index> |
68 |
for self-compiled version. If you use Debian GNU/Linux package specify |
69 |
B<index++>. See C<Debian>. |
70 |
|
71 |
=item C<search> |
72 |
|
73 |
Full or partial path to SWISH++ search executable. By default, it's B<search>. |
74 |
|
75 |
=item C<debug> |
76 |
|
77 |
This option (off by default) will produce a lot of debugging output on |
78 |
C<STDERR> prefixed by C<##>. |
79 |
|
80 |
=item C<meta_in_body> |
81 |
|
82 |
This option (off by default) enables to search content of meta fields |
83 |
without specifying them (like they are in body of document). This will |
84 |
somewhat increase index size. |
85 |
|
86 |
=item C<use_stopwords> |
87 |
|
88 |
Use built-in SWISH++ stop words. By default, they are disabled. |

=head2 Debian |
661 |
|
662 |
Debian version of SWISH++ is often old (version 5 at moment of this writing |
663 |
while version 6 is available in source code), so this module by default |
664 |
uses executable names B<index> and B<search> for self-compiled version |
665 |
instead of one from Debian package. See L<new> how to specify Debian |
666 |
default binaries B<index++> and B<search++>. |
667 |
|
668 |
=head2 SWISH++ |
669 |
|
670 |
Aside from very good rewrite in C++, SWISH++ is faster because it uses |
671 |
claver heuristics about which data in input files are words to index and |
672 |
which are not. It's based on English language and might be best choice if |
673 |
you plan to index large amount of long text documents. |
674 |
|
675 |
However, if you plan to index all data from structured storage (e.g. RDBMS) |
676 |
you might want B<all> words from data to end up in index as opposed to just |
677 |
those which look like English words. This is especially important if you |
678 |
don't plan to index English texts with this module. |
679 |
|
680 |
With distribution build versions of SWISH++ you might have problems with |
681 |
disapearing words. To overcome this problem, you will have to compile and |
682 |
configure SWISH++ yourself (because language characteristics are |
683 |
compilation-time option). |
684 |
|
685 |
Compilation of SWISH++ is easy process well described on project's web |
686 |
pages. To see my very relaxed sample configuration take a look at C<swish++> |
687 |
directory included in distribution. |
688 |
|
689 |
=head2 SWISH++ config |
690 |
|
691 |
C<config.h> located in C<swish++> directory of this distribution is relaxed |
692 |
SWISH++ configuration that will index all words passed to it. This |
693 |
configuration is needed for B<date test> because default configuration |
694 |
doesn't recognize 2004-12-05 as date. Have in mind that your index size |
695 |
might explode. |
696 |
|
697 |
=head1 BUGS |
698 |
|
699 |
Currently there is no way to specify which meta data will be stored as |
700 |
properties. B<This will be fixed very soon>. |
701 |
|
702 |
There is no garbage collection on temporary files created for SWISH++. This |
703 |
means that one run of indexer will take additional disk space for temporary |
704 |
files, which will be removed at end. There should be some way to remove |
705 |
files after they are indexed by SWISH++. However, at this early stage of |
706 |
development it's just not supported yet. Have plenty of disk space! |
