Box 4: (Search Result Web Part)
Here are some tools that make Cross-Site Publishing happen.
/ Content Search Web Part:
It allows to build your own query using a wizard, this means fetching the content you want to see, and then allows you to display them using predefined
display templates. It uses Search to query, which therefore allows us to show content from another Site.
/ Search Results Web Part:
It can either show the results of a typed query in the Search Box, which is the traditional Search Results we know. But, and this is key, the Search Results also allows you to build a Query using the same Query Builder in the Content Search. In fact, I have found the Search Results to offer 95% of the same functionality as the Content Search. Therefore, it can also be used in Cross-Site Publishing Scenarios.
