Since eBay changed the way their search feature works you see a bunch of crap you don’t want. eBay’s search feature works similar to Google’s search engine and so do a the little known commands. These will help you better target your search results if you’re seeing a bunch of non-relevant items pop up.
Example: if you’re searching for 1969 Cougar and want to filter out the non-relevant items you can add negative search words like -fits -interchange etc. Also adding quotations around the search term like “1969 Cougar” will target your results. Try it!!
