Mar 1, 2025March 2025 (libris/lxlviewer): Delivered a significant upgrade to the search experience and UI reliability. Replaced the Search component with SuperSearchWrapper to unlock advanced search capabilities, redesigned the search suggestions UI for clearer actions and qualifiers, and enhanced qualifier handling (unquoting and wildcard support) for more accurate results. Fixed a UI-state edge by preventing default indices when start content isn’t shown, improving render correctness. As a temporary CI stabilization, disabled a failing end-to-end test related to SuperSearch to unblock CI while root cause is investigated. These changes drive business value by delivering faster, more capable search, greater user satisfaction, and smoother development cycles.
