I'm currently implementing percolator for Elastica. I looked at the
examples and everythings works as expected.

But I'm somehow curious about the "type" param for example in the third
example (matching queries). The type is named "type1". As far as I
understand, it could be anything else like "abcde" and would return the
same result. Or if not, what is the type for?
