No, updating multiple documents in a single request is not supported in Solr.

You'll have to retrieve the list of documents (i.e query for city:Delhi), then issue an atomic update for each one:

[
    {"notificationId":"retrievedId1", "status":{"set": 0}}, 
    {"notificationId":"retrievedId2", "status":{"set": 0}}, 
]

Include the _version_ parameter from each document to avoid overwriting changes made by other threads in the meantime (optimistic concurrency) if necessary.
