---------------------------------------
jorgelbg opened a new pull request #400: NUTCH-2663 Improve the JEXL syntax for
getting values from the context
URL: https://github.com/apache/nutch/pull/400
* Avoids the use of the array notation when getting values from the
document/metadata(s) on the JEXL expression. We go from `doc.lang[0] == 'en'`
to `doc.lang == 'en'` which is more easy to understand.
* Log using errors instead of warnings in the `setConf` methods. We throw a
`RuntimeException` if something is wrong, so the log should represent the same
severity level.
* Some minor changes an additional comments.

> Improve index-jexl-filter syntax for scripts
> --------------------------------------------
>
> Key: NUTCH-2663
> URL: https://issues.apache.org/jira/browse/NUTCH-2663
> Project: Nutch
> Issue Type: Improvement
> Components: plugin
> Affects Versions: 1.16
> Reporter: Jorge Luis Betancourt Gonzalez
> Assignee: Jorge Luis Betancourt Gonzalez
> Priority: Minor
>
> JEXL scripts need to be written using the array syntax to get the actual
> value (for instance, example extracted from the tests):
> {code}
> doc.lang[0]=='en'
> {code}
> Ideally, this would only be required if the actual value is really an array,
> and not for single value elements.
