Google has a search engine.
We’re all familiar with it.
It’s at google.com.
Search engines that search specific sub-groups of the web are known asvertical search engines.
Google also calls them “specialized search.”
Google has quite a few of these specialized search engines.
However, some of Google’s search engines are separate search engines with their own URL.
Google Scholar is a vertical search engine dedicated to finding scholarly research.
Academic library databases are often difficult to search.
It’s also the method that was used as the foundation for Google’s PageRank.
Google Scholar can also send you alerts when new scholarly research is published on topics of interest.
Google Patent Search
Google Patents is one of the more hidden vertical search engines.
Google Patent search can search through names, topic keywords, and other identifiers for patents around the world.

you’re free to filter searches by things such as vendor, price range, or local availability.
