> "When you configure a job to use a Solr-type output connection, the Solr 
> connection type provides a tab called "Field Mapping". The purpose of this 
> tab is to allow you to map metadata fields as fetched by the job's connection 
> type to fields that Solr is set up to receive. This is necessary because the 
> names of the metadata items are often determined by the repository, with no 
> alignment to fields defined in the Solr schema. You may also suppress 
> specific metadata items from being sent to the index using this tab. 
> Add a new mapping by filling in the "source" with the name of the metadata 
> item from the repository, and "target" as the name of the output field in 
> Solr, and click the "Add" button. Leaving the "target" field blank will 
> result in all metadata items of that name not being sent to Solr."
> In my opinion we should change the way a metadata field is suppressed.
> The most natural way is that we express only the mappings of the metadata 
> fields we want to keep.
> All the missing params will not be sent to Solr.
> The improvement will be :
> - same interface with a boolean flag in addition, this flag will specify if 
> the missing metadata fields not expressed should be sent to Solr with the 
> original names or not sent at all.
> In this way if we want to keep 3/100 metadata fields, we don't have to write 
> 100 mapping entries , 97 empty but simply 3 entries and activate the flag.
