The item you are searching for does not seem to be on this web site.
If you are searching on more than one word, it makes a difference whether you use quotation marks, for example "new computer" will only return a result if the words new and computer are next to each other, whilst dropping the quotes and typing in new computer will also find a reference to new 1995 computer.
Not using quotation marks can in some circumstances deluge you with reponses, so tread warily.
You can use an asterisk (*) as a wild card character- for example comput* will match both computer and computing.
You may use a plus and negative sign immediately in front of a word or phrase to ensure that word/phrase is matched (+) or to ensure that matches with the word are excluded (-). eg +comp* -compare
Or perhaps you are just on the wrong web site, in which case please return to my search engine page and give Startpage a try.
