Advanced Search — Use this search option to create complex searches using field tags and set combinations. Each search term must be prefaced by a field tag, and search terms must be joined by Boolean operators.

In this example, we are searching for information about robotic vision that uses colour histograms for object detection. We have combined sets #1 and #2 using the AND Boolean operator to create set #3. This new set includes 14 records that appear in both set #1 and set #2.
