#189 Study faceted search not including variables that are not described in SDDs

[paulopinheiro1234]

The study faceted search is performed on top of RDF content derived from SSDs and SDDs. Some key variables such as target analytes can only be inferred from data. Thus, in a project like HHEAR, the study faceted search cannot be used without target analytes being shown.

This task consists of expanding the SOLR study collection to include the results of SOLR faceted queries returning the summary of in_relation_to_str values. On a study base, these values should be included to the SOLR study collection.
