Adrien Grand commented on LUCENE-6764:
--------------------------------------
Actually I was thinking of something simpler... The current postings format
encodes everything into blocks of 128 values, so we could do dictionnary
encoding independently on each block.
> Payloads should be compressed

> Key: LUCENE-6764
> URL: https://issues.apache.org/jira/browse/LUCENE-6764
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Adrien Grand
> Priority: Minor
>
> I think we should at least try to do something simple, eg. deduplicate or
> apply simple LZ77 compression. For instance if you use enclosing html tags to
> give different weights to individual terms, there might be lots of
> repetitions as there are not that many unique html tags.
