You have several options here: 1. Use the deletedPkQuery in delta import - you'll need to make a DB query which generates the IDs to be deleted (something like: SELECT id FROM your_table WHERE deleted = 1). 2. Add the $deleteDocById special command to your full/delta import. 3. Use preImportDeleteQuery/postImportDeleteQuery in your full/delta query
If you want to use any of these separately from your import, you can put them in a separate entity and do a full/delta import just on that entity.

Your solution do make sense. Actually i wanted to know, how to use delete via query or unique id through DIH? Is there any specific query to be mentioned in data-config.xml? Also Is there any separate command like "full-import" ,"delta-import" for deleting documents from index?
