Creates executable plans for the provided query. It is required to call one of the initializePlanner() methods before calling this method.

Parameters:

querySpec -

boundVarIndices - a set of integers representing the variables that are bound

Returns:

a mapping between ISearchOperation list and a mapping, that holds a PVariable-Integer mapping for the list of ISearchOperations

Throws:

QueryProcessingException
