Wildcards are more efficient when used at the end of strings because they allow for a broad search without needing to evaluate the entire string that precedes the wildcard. When a wildcard is placed at the beginning or in the middle of a string, it can significantly increase the complexity of the search operation since the search engine needs to check multiple possible combinations before arriving at the desired match. Using a wildcard at the end restricts the scope of the search to only the matching initial segment, which optimizes performance by reducing the amount of data processed. This is particularly useful in scenarios where the beginning of a string has consistent, known characters or patterns, allowing for quicker lookups and processing. While wildcards can be used judiciously in various contexts, their placement critically impacts efficiency, making them most advantageous when applied at the end of strings.
