I like that you can search through different fields which makes your research easier as well quicker than if they had just one field only! It's also very easy/quickly navigate around each page when looking at results from previous searches or even new ones made within this site itself - there are many tabs so finding what i'm after isn't always too difficult but sometimes takes some time (especially during busy periods & holidays).
Sometimes navigating back up pages may not be possible due certain filters being applied however these aren’t often used unless searching specifically under them anyway? As stated above though using multiple filter options does seem much faster once found compared other sites where filtering down seems slower especially those who use specific keywords rather then browsing freely across several topics etc.. If anything could maybe improve would probably need better help guides available online about how best ways / methods work together eg.: How do we combine 2+ queries such us AND OR vs 1 query + additional.
