Search improvements

We have made improvements for a search that now you will get better results when searching genre and year.   Example these searches will now take you to the right place immediately: - best fantasy books of 2023 - young adult 2023 - 2023

New features! Now you're able to get book lists from decades and even centuries.   If you search for books older than 2 years old you will get a book list from that decade. Like searching "best science fiction books 1976" will get you a book list from 1970s best books (1970-1979).   For getting a book list by target century you need to make a search where the year is older than 1910. Like searching "fantasy books 1901" will get you a best books list from the 19th century (1900-1999). All these decades and centuries by genre are also shown on [url=/library/genre/fantasy]genre's page[/url].
