Subject [jira] [Created] (NUTCH-1985) Adding a main() method to the MimeTypeIndexingFilter
Date Tue, 14 Apr 2015 20:30:59 GMT
Jorge Luis Betancourt Gonzalez created NUTCH-1985:

             Summary: Adding a main() method to the MimeTypeIndexingFilter
                 Key: NUTCH-1985
             Project: Nutch
          Issue Type: Improvement
          Components: indexer, metadata, plugin
    Affects Versions: 1.10
            Reporter: Jorge Luis Betancourt Gonzalez
            Priority: Minor
             Fix For: 1.10

This make very easy the testing of different rules files to check the expressions used to
filter the content based on the MIME type detected. Until now the only way to check this was
to do test crawls and check the stored data in Solr/Elasticsearch. 

This allows calling the file using the {{bin/nutch plugin}} command, something like:

{{bin/nutch plugin mimetype-filter org.apache.nutch.indexer.filter.MimeTypeIndexingFilter

Two options are accepted, {{-h, --help}} for showing the help and {{-rules}} for specifying
a rules file to be used, this makes easy to play with different rules file until you get the
desired behavior. 

After invoking the class, a valid MIME type must be entered for each line, and the output
will be the same MIME type with a {{+}} or {{-}} sign in the beginning, indicating if the
given MIME type is allowed or denied respectively.
