attributeError: 'SQLDocumentStore' object has no attribute 'query'

To author:
I have changed the retriever to Elasticsearch, but got the following error, do you have any idea about it?

Hey @laifuchicago,

The ElasticsearchRetriever is only compatible with an ElasticsearchDocumentStore as it relies on the indexing and scoring functions of ES. It seems that you passed a SQLDocumentStore to the retriever. We will add a clearer Error Message here to avoid any confusion in the future...

Thank you, it can be used now.
