Today, we’re introducing another tool that is hopefully intuitive as well as interesting : You can discover hundreds of sites to include in your CSE starting just with keywords! For example, for a CSE on “global warming”, adding keywords like [pollution], [global warming] and [greenhouse effect] can lead you to discover global warming related sites within minutes.
This tool attempts to combine Google’s knowledge with the topic expertise you have - Google suggests sites, but you can control the topic expansion, and guide the tool towards your topic in a fine grained way.
The tool is accessible off of the New Search Engine page on the Custom Search control panel. Give the tool a whirl, see more details on how the tool works in our documentation, and let us know what you think on the product forum.
