What is the limit on the number of Service Desk Manager Knowledge Documents available via Search in Unified Self Service?
There is a limit of 10 documents that can be shown from the Service Desk Manager knowledge base here.
Service Desk SOAP Web Services API's Search module is used by USS for this (https://docops.ca.com/ca-service-management/17-1/en/reference/ca-service-desk-manager-reference-commands/technical-reference/web-services-knowledge-management#WebServicesKnowledgeManagement-search).
At this time, the 10 value is not configurable via any options/parameters in USS. User needs to filter out search strings further to get much narrowed set of results.
