Perl Module:

Foswiki::Query::ConditionalOP - Base class for binary conditional operators.
Foswiki::Query::HoistREs - Static functions to extract regular expressions from queries. The REs can be used in caching stores that use the Foswiki standard inline meta-data representation to pre-filter topic lists for more efficient query matching.
Foswiki::Query::Node - A Node object is a single node in a query (either a tree node or a leaf node). A tree of node objects represents a query over the Foswiki database.
Foswiki::Query::OP - Base class of operators used in queries. Operators are singleton objects that specify the parser behaviour and are attached to nodes in the parse tree to provide semantics for the nodes.
Foswiki::Query::OP_and - N-ary AND function. Given an expression like a AND b AND c, this operator will build a single node that has 3 parameters, a, b, and c.
Foswiki::Query::OP_comma - List-building n-ary operator.
