Google and all search engines use highly efficient crawlers that parse webpages and extract data from them. Nobody except them knows how their crawler is implemented, but they have 1000000s of computers that are churning through the web, so your phone can't possibly compete with that! As I mentioned, JSoup is probably your best best. It has really nice APIs for extracting certain elements. If you know the tags you want, then use Jsoup to parse the document and then pluck them.
I'm not sure what you mean by which technology Android uses? Uses for what exactly? When you use Google on your phone it's just querying google, there is no searching happening on your phone.
