Preserve special characters in Dynamic Search text matching

Dynamic Search currently strips special characters, such as '#', from search terms before matching, causing the search to return results based on the remaining substring rather than the exact term entered. This enhancement proposes updating Dynamic Search to preserve special characters during matching so that a term such as 'link#' returns only exact matches rather than all results containing 'link'. Customers searching for device or interface names that include special characters would receive precise results and avoid manually filtering out unrelated matches.
