ConnectionTimeOut Error with DensePassageRetrieval

[anirbansaha96]

Question
What is the way out to solve ConnectionTimeOut issue when we use the finder to ask questions?

Additional context
I'm getting the following error when I'm using the DensePassageReriever

ConnectionTimeout: ConnectionTimeout caused by - ReadTimeoutError(HTTPConnectionPool(host='localhost', port=9200): Read timed out. (read timeout=10))

The detailed Error Log is:

Hi @anirbansaha96, the default connection timeout for the Elasticsearch query is 10 seconds. With #243, the timeout will be increased to 300 seconds and that should resolve the issue.

Thank You!
