Per the product design, the feature that enables ordering the search results by Title is available under the Administration tab (see screenshot below). The Administration tab is available when running under the Administrator role.
For analysts without access to the Administration tab, the search would be done via the Knowledge tab. When Relevancy is selected in the Order By dropdown, the Title is a weighted factor in the ordering of the list of results.
The weighting of the Title can be changed for the environment if necessary through the EBR_TITLE_WEIGHT environment variable in the NX.env file.
Other environment variables that are factors in Relevancy are EBR_SUMMARY_WEIGHT, EBR_PROBLEM_WEIGHT, and EBR_RESOLUTION_WEIGHT.
The following is a screenshot showing that search results may be ordered by Title when the search is done via the Administration tab:
