docs: Perform a prefix search using the provided prefix string
  
              Args:
                  prefix (str): Prefix string to use for search
                  results (int): Number of pages with the prefix to return
              Returns:
                  list: List of page titles
              Note:
                  **Per the documentation:** "The purpose of this module is \
                  similar to action=opensearch: to take user input and provide \
                  the best-matching titles. Depending on the search engine \
                  backend, this might include typo correction, redirect \
                  avoidance, or other heuristics."
