How to create advanced queries with a series of AND/OR's?

You can also use sub queries

<q>[[Category:Person]] [[Hair color::brown]]</q> OR <q>[[Hair color::black]] [[Eye color::blue]]</q> OR [[Eye color::green]]

Not sure which forms are the most efficient. Probably not this one.

If you're suggesting that ... can also be used in the same way as the rounded brackets above, then it would be powerful piece of syntax that is worth documenting.
