search api block search view gives me duplicate variations of the product

The Search API doesn’t have a concept of products, variations or even entities – it just knows the item it has indexed, and each one is a separate object that is returned independent of any others. I.e., if you want to return each product only once, you need to index products, not variations. I don’t know enough about Commerce internals to help with that, but it’s apparent that variations of your product are indexed as separate items in the Search API, so you have to prevent that from happening. Most likely, this can be done by selecting a different “datasource” in the search index settings, but, again, I don’t know enough about Commerce (or your setup) to be sure.
