To achieve this, first you need a Search Service Application in your farm (no need to recreate if already exists). Then you have to create a Search Center type site anywhere in your SharePoint site i.e.
http://yoursite/SubSite/Search. Better if you create under the same web application and site collection with inherited permissions. Now for all of your terms in MetaData set the URL of the term URL Like below for example.
Term Title : Books
Term URL :
You can replace the word Books in above URL with each word you want to search with and change the Title too accordingly.
Now clicking on the navigation link Books will redirect to a search page that will search for you for the word Books used anywhere i.e. pages, documents etc. You can further filter your search in the result page.
If you want a page or item to get searched and show in results on clicking the navigation link, Tag that page or item with specified word and make sure that is get crawled in the search.
