Broadleaf Commerce Discussion Forums

I have extended ProductImpl to create my CustomProductImpl with some new fields/attributes. One of the field added to my CustomProduct table is - workflow_status( using Broadleaf Workflow).

My SearchController extends BroaleafSearchController that uses SolrSearchServiceImpl for catalog search. By default it is searching all the items from Product. However, my requirement is to pull only the published items(in extended CustomProduct) table.

How can I inject my condition/searchcriteria into Solr search query (e.g. ...where workflow_status='PUBLISHED') to pull only the published item.?

Thanks in advance.!!
