How is it that I type in a word and a search results page appears that helps me, even though the term itself doesn't appear in it? 

When a search term is entered, our intelligent search algorithm compares it with the names of existing categories and their associated keywords. Each category is connected to up to 25 keywords, including synonyms, abbreviations, and similar terms. This means that you may see search results even if your exact search term is not explicitly mentioned. For instance, if you type in "helicopter," you will be shown products and companies related to helicopters.
