29 =head1 NAME
30
31 run.pl - start WebPAC indexing
32
33 B<this command will probably go away. Don't get used to it!>
34
35 =head1 OPTIONS
36
37 =over 4
38
39 =item --offset 42
40
41 start loading (all) databases at offset 42
42
43 =item --limit 100
44
45 limit loading to 100 records
46
47 =item --clean
48
49 remove database and Hyper Estraier index before indexing
50
51 =item --only=database_name/input_filter
52
53 reindex just single database (legacy name is --one)
54
55 C</input_filter> is optional part which can be C<name>
56 or C<type> from input
57
58 =item --config conf/config.yml
59
60 path to YAML configuration file
61
62 =item --stats
63
64 disable indexing, modify_* in configuration and dump statistics about field
65 and subfield usage for each input
66
67 =item --validate path/to/validation_file
68
69 turn on extra validation of imput records, see L<WebPAC::Validation>
70
71 You can use special variables C<$database> and $C<$input> in this parametar
72 like C<--validate 'conf/validate/$database-$input'> to construct filename
73
74 =item --validate-delimiters path/to/validate_delimiters_file
75
76 this option is used with C<--validate> to turn on extra validation of
77 delimiters. If file is non existant, it will be created on first run.
78
79 =item --marc-generate
80
81 Generate MARC file. This will automatically be on if file contains C<marc*> directives.
82 You can use this option as C<--no-marc-generate> to disable MARC generation.
83
84 =item --marc-lint
85
86 By default turned on if normalisation file has C<marc*> directives. You can disable lint
87 messages with C<--no-marc-lint>.
88
89 =item --marc-dump
90
91 Force dump or input and marc record for debugging.
92
93 =item --parallel 4
94
95 Run databases in parallel (aproximatly same as number of processors in
96 machine if you want to use full load)
97
98 =item --only-links
99
100 Create just links
101
102 =item --merge
103
104 Create merged index of databases which have links
105
106 =back
