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