List of decompressPositions() Examples

Examples of decompressPositions()

ivory.ffg.data.CompressedPositionalPostings.decompressPositions()
Retrieves positions for a document given a forward index and the index of the document in the document id vector. @param skipList Forward index decompressed using {@link #decompressSkipList}. @param index Index of the document id in the document id vector @return Positions of the occurrences of the term within a document
ivory.ffg.data.DocumentVector.decompressPositions()
Decompresses/constructs positions. This method applies the necessary transformation functions tot he input query terms. @param terms Query terms @return Position arrays for every term in the query
