Queries posted to /queryjobs such as those from the LogScale UI can either start on the local node that receives the request, or get proxied to the node that is the most likely to run the query if another instance of the same search has already started. This helps sharing identical searches in a cluster. Setting this to false makes requests execute locally on the node that receives them.
