Unlike other Chart Library filters, when selecting more than one Channel or Gate, the search results will display only those charts with the exact combination you have selected.
For example, if you select Gate 10 and Gate 15, your search result will display only people with both Gate 10 and 15 activated in their chart. If you then also select Channel 20-34, the search results will be refined to show only people with Gate 10 and 15 activated, and Channel 20-34 defined, in their chart.
Other filters adopt the OR method of showing search results. For example, if you select Generator and Reflector, your search will show both Generators OR Reflectors—not a combination of the two which does not exist.
