The search returns a vector of SubstringOccurence objects, which is then printed out. Each occurence represents a single match of the pattern. The pattern has to be matched within a single sentence. Information about the match consists of two integer values: ID of the sentence where the match occured and word-level, 0-based offset of the matched pattern in the sentence.
