Subject: [PATCH] fix(localSearch): update indexing logic to handle MiniSearch
 duplicate ID (#4251)

Introduce a check to discard duplicate IDs before adding them to the index in the localSearchPlugin. This ensures that each ID is uniquely indexed, preventing any potential overwriting of existing entries. The modification enhances the reliability and accuracy of the local search functionality.
