Explore Advanced Search options within v7.14.2:
While basic search may be limited, v7.14.2’s advanced search should still offer more comprehensive querying capabilities. Dive deeper into its filters, operators, and conditions to see if they can fulfill your search needs.
Utilize SugarLive for enhanced search:
If searching across diverse modules and fields is crucial, consider installing the SugarLive module. It offers a modern search interface with filters, facets, and other features that might closely resemble the previous advanced search.
