Feature
Allow customization of the default page size in search results

Describe the task
Currently, the default page size for search results is fixed at 10 items per page. It would be helpful to provide a way to customize this default value, either through a configuration setting or an environment variable. This feature would enable users to tailor the search experience to their needs without having to manually change the page size every time.
