Make sure you use the radio buttons to restrict the search to the specific area. As an example, if you are interested in searching our Tenders database, the Tender option must be selected on the search bar.
Check spelling
Make sure your search terms are spelled correctly.
Use multiple words
Using multiple words will return more refined results than a single word. For example, typing "agricultural machinery" will return more relevant results than typing just "machinery". (Keep in mind that relevant results are returned even if they don't contain all query terms.)
