Try words which have a similar meaning
For example, you'll get two different lists of items when you search for wedding dress
and bridal gown
Use specific words instead of general ones
For example, a search for Beatles
poster will return fewer, more-targeted listings than a search for Beatles.
For a closer match, specify a date, color, or brand
For example, to find a particular Barbie item, don't just type Barbie in the search box. If you want only red dresses, type: Barbie red dress. Remember: Be specific and narrowly define your search!
Search titles and descriptions to get more matches
Search always looks for your keywords in the title of the items for sale. Click on search titles and descriptions under the search box to also search item descriptions. You'll get many more results.
Be careful when using and, or, and the
eBay's search engine searches for and, or, and the just like it would any other word. Use and, or, and the only if you're searching for items containing these words, such as Diana Ross and the Supremes or Truth or Dare.
Don't use extra punctuation
Only use punctuation in your search if you expect it to be in the item title or description for which you're searching. Examples include t-shirt, N-Sync and Dr. Watson.
If you're not searching for something specific, try browsing through the category listing pages for surprising discoveries.
