使用阻塞压缩压缩反向索引

Question

我已经构建了一个文本集合的倒排索引字典，需要使用阻塞压缩k = 8来压缩字典，并且在发布文件中，使用gamma编码的docids之间的间隙

   def createCompressedIndex(dictionary_uncomp_v1):
        for term in dictionary_uncomp_v1.keys():
             entry = dictionary_uncomp_v1.get(term)
             postingList = []
             prevId = 0
             pEntry = PostingEntry(0,0,0,0)
             for pEntry in entry.postingList:
                 docId = getGammaCode(pEntry.docId - prevId)
                 frequency = getGammaCode(pEntry.termFreq)
                 newPEntry = PostingEntry(docId,frequency,0,0)
                 postingList.extend(newPEntry)
                 prevId = pEntry.docId
                 ptemp = docId+frequency

             docFrequency = getGammaCode(entry.docFreq)
             entrytemp = ptemp+docFrequency
             totalTermFreq = getGammaCode(entry.totTermFreq)
             compressedEntry =  DictEntry(term,docFrequency,totalTermFreq,postingList)
             dictionary_comp_v1[term] = bytearray(entrytemp)
