Fix page_url assignment in search route

The page_url variable in the search route was not being properly assigned in certain cases. This commit fixes the issue by ensuring that page_url is assigned the correct value based on the search parameters.

In the match expression, the conditions have been adjusted to correctly handle the page number and construct the appropriate page_url. This ensures that the generated URL for the search page is accurate and reflects the search query and page number.

This change improves the functionality and reliability of the search route by correctly setting the page_url variable based on the provided search parameters.
