Chaining boolean operations

Boolean operations can be chained indefinitely (although chaining more will update more slowly). In the above example, we see that the intersection is joined with the Fishing group by using union. All of documents that are in Fishing are now joined with the intersection results.

In this example, many operations are chained together to produce a desired outcome. The first intersection produces only documents that contain both pizza and jalapenos; the second intersection produces only documents that contain both pizza and mushrooms. The results are joined together, then ranked with a Teleoscope according to a search for garlic.

Due to the logic of Boolean operations, you could get the same result by using the same operations in a different order. In the above, the searches are joined with union, and then the union is interesected with the pizza search.
