When a search is performed for catalog items the drop-down search results are not sorted alphabetically.
Drop-down search results for catalog items are not sorted alphabetically
This is expected platform behavior because the search results are based on a search of a calculated weight done by the Zing search engine within the platform. How this works can be understood in detail at:
The following example is based on OOB demo data for catalog items:
1) Navigate to Maintain Items module and do a "for text" search for "Plan"
2) Sort the result by Name <a-to-z> and see that items appear in alphabetically order
3) Navigate to Self-Service > Service Catalog module and search "Plan" on the search box located on top right
4) Notice that the results are not sorted in alphabetical order
