Lucy::Search::PolyQuery – Base class for composite Query objects.
PolyQuery serves as a shared base class for ANDQuery, ORQuery, NOTQuery, and RequiredOptionalQuery. All of these classes may serve as nodes in composite Query with a tree structure which may be walked.
void lucy_PolyQuery_Add_Child( lucy_PolyQuery *self, lucy_Query *query );
Add a child Query node.
cfish_Obj* // incremented lucy_PolyQuery_Dump( lucy_PolyQuery *self );
bool lucy_PolyQuery_Equals( lucy_PolyQuery *self, cfish_Obj *other );
Indicate whether two objects are the same. By default, compares the memory address.
lucy_Compiler* // incremented lucy_PolyQuery_Make_Compiler( lucy_PolyQuery *self, lucy_Searcher *searcher, float boost, bool subordinate );
Abstract factory method returning a Compiler derived from this Query.
A scoring multiplier.
Indicates whether the Query is a subquery (as opposed to a top-level query). If false, the implementation must invoke Normalize() on the newly minted Compiler object before returning it.
void lucy_PolyQuery_Set_Boost( lucy_PolyQuery *self, float boost );
Set the Query’s boost.
float lucy_PolyQuery_Get_Boost( lucy_PolyQuery *self );
Get the Query’s boost.
