Unit 6. Searching for resources

6.2. Search engines

There are different types of search engines available, from the most general ones to engines specialized in searching copyrighted resources.

The generic engines are general internet search engines such as Google and Bing. Generic engines can be used to find resources on the internet. They could also be used to find license information about the resource if it is included in text form in the same place as the resource, although the precision of this search varies.

Some of these generic engines have been adapted to include filters based on license information in the search for a specific type of resource, and sometimes other information for the metadata of the resource. For example, Google can search for images, filtering by the CC license, and image properties such as size and resolution.

There are also engines specialized in searching for a type (or types) of resource (for example, icons search). Most of them can search not only using specific properties of the resource (metadata) and the content, but also using license information.
