What may be the possibility?

What do you think is the possibility in getting different results everytime I search a single item?

1. There may be different databases being searched that have not been synchronized yet. That is often seen on Google.

2. Some search engines are now showing different results and different ads based on profiles or recent searches. They may show different results or ads intentionally based on the idea that if you didn't click on them the first time they weren't as "relevant" as they could be - so they show you different choices.

Yes all main search engines now have "personalized search results", but you have always option to turn that off.
Personaly I don't like this as a both, search engine user and search engine marketer.

yes, Internet technology is advancing daily and so are search engines. There are many advancements still to come sooner or later

I think it is not the rapidly changing technology but it was some type of error!
