 226         if (tag.size() >= CHUNK_SIZE_THRESHOLD) write_tag();
 #define CHERT_DEFAULT_BLOCK_SIZE 8192


 Whether I can modify function append_to_stream for  the following ?

 216     void append_to_stream(Xapian::docid did, const string & value) {
 217         Assert(did);
 218         if (tag.size()+sizeof(did)+1+value.size() >=
 table->block_size) write_tag();
 219
 220         if (tag.empty()) {
 221             new_first_did = did;
 222         } else {
 223             AssertRel(did,>,prev_did);
 224             pack_uint(tag, did - prev_did - 1);
 225         }
 226         prev_did = did;
 227         pack_string(tag, value);
 228     }
