Have you verified that performing this search via Dev Tools yields the proper hits count?
Is there a reason you're leaving the client on 6.3 instead of moving to 7x?
Even though it may work, it's still recommended to keep the client on the same version as the stack.
Also, you may want to consider going to the latest release in 7.17.x as 7.10 is EOL.
I am eventually planning to bump the client up as well. If it was forwards compatible, it would make for a smooth rolling upgrade such that I wouldn't have to coordinate between upgrading the cluster version and updating code to use the new client
