------------------------------------

             Summary: Document SolrCells' use of the meta field
                 Key: SOLR-3438
                 URL: https://issues.apache.org/jira/browse/SOLR-3438
             Project: Solr
          Issue Type: Improvement
          Components: contrib - Solr Cell (Tika extraction)
            Reporter: Jack Krupansky
            Priority: Minor


SolrCell will add document metadata to the field named "meta" if it is present in the schema.
This is undocumented behavior and can be surprising and confusing to users who explicitly
added a field named "meta" to their schema for their own purpose without any awareness that
SolrCell would be populating it with document metadata.

This issue merely proposes to clearly document the use of the "meta" field, but several questions
do arise:

1) Is this behavior actually intended as a released future? As opposed to some experimental
work that wasn't intended for release just yet.

2) Should there be a request parameter to be able to disable this feature?
2a) Should the default be to have to enabled?

3) Should the "meta" field be added to the example schema (the section for SolrCell metadata
fields) to reinforce the fact that a user should not blindly add their own "meta" field for
some other purpose?

4) Should there be a request parameter to redirect this behavior to a named field?
4a) Should the default name be more explicit (e.g., solrcell_metadata)?

This issue is only intended to address documentation related to question #1. If the answers
to any of the other questions are "yes", a separate issue can be opened. That said, I do lean
towards adding the "meta" field to the example schema as part of the "documentation."

For reference I'll attend a snippet from a query result that has the "meta" field populated
by an extracted Word document.
