Compound database filter — compound

The compound_filter function combines two filters into a compound one. These filters can either be compound filters themselves, or single-level filters as described in property_filter. This filter is only meant for use within the query_database function.

compound_filter(x, y, type = "and")

Arguments

x	A property filter; either compound or single-level.
y	A property filter; either compound or single-level.
type	A string indicating what type of compound filter. Must be either `"and"` or `"or"`.

Value

A structured compound filter.

Details

Compound filters can be nested up to 2 levels deep. Currently there is no checking for this, so it's on the user to adhere to it.
