Does Google show all results?

It's not possible to see "all" the results. The number that appears at the top of the first page of search results, "About nnn results", is Google's statistical estimate of how many indexed web pages there might be that match the search terms. That estimate may be close, or it may be way off -- there's no way to tell!

How do I get more Google search results?

When you search on Google, you may find thousands or even millions of matching web pages. The most relevant results are displayed first. To find more web results, click Next or More Results at the bottom of the search results page.

What is query rule?

Query rules help searches respond to the intent of users. In a query rule, you specify conditions and associated actions. When a query meets the conditions in a query rule, the search system performs the actions specified in the rule to improve the relevance of the search results.

What is query rules in SharePoint 2013?

For example, a query rule condition could be that a term in a query matches a particular term in a SharePoint Server term set, or that a query is frequently performed on a particular result source in a search system, such as videos.
