Doc values terms dictionaries keep the first term of each block uncompressed so that they can somewhat efficiently perform binary searches across blocks. Suffixes of the other 63 terms are compressed together using LZ4 to leverage redundancy across suffixes. This change improves compression a bit by using the first (uncompressed) term of each block as a dictionary when compressing suffixes of the 63 other terms. This helps with compressing the first few suffixes when there's not much context yet that can be leveraged to find duplicates. -- This is an automated message from the Apache Git Service.
