c68d17d482 (keyword-extraction) Fix bug leading to position data missing on some keywords. 
This was due to a discrepancy between the KeywordPositionBitmask and WordsTfIdfCounts' concept of a keyword.

bafc2a1f30 (reverse-index) Force() final docs after being written 
Unlikely to be a problem, but we want to ensure it's on dsik before we go read it later.

563e388a45 (reverse-index) Fix parallel documents sorting bug 
Bug was caused by parallel sorting capturing the iterator rather than the offsets to sort.

320dad7f1a (index journal) Fix leaky abstraction in IndexJournalReader. 
The caller shouldn't be required to know the on-disk layout of the file to make use of the data in a performant way.

f321fa5ad3 (array) Override to Paging...Array$range() 
This is a big performance boost in array.range().get().

Without an override, each access will go through pages[page].get(...) for each get()-operation.  This adds up very quickly.  BTreeReader does a bunch of get():s on a range()'d array during traversal in the queryData... methods.

3101b74580 (index) Move to a lexicon-free index design 
This is a system-wide change.  The index used to have a lexicon, mapping words to wordIds using a large in-memory hash table.   This made index-construction easier, but it
also added a fairly significant RAM penalty to both the index service and the loader.

The new design moves to 64 bit word identifiers calculated using the murmur hash of the keyword, and an index construction based on merging smaller indices.

It also became necessary half-way through to upgrade guice as its error reporting wasn't *quite* compatible with JDK20.

460998d512 (index) Move index construction to separate process. 
This provides a much cleaner separation of concerns, and makes it possible to get rid of a lot of the gunkier parts of the index service.  It will also permit lowering the Xmx on the index service a fair bit, so we can get CompressedOOps again :D

SWAP_LEXICON doesn't instruct the index service to do anything.  It just moves the file.

6a04cdfddf (loader) Implement new linkdb in loader 
Deprecate the LoadUrl instruction entirely. We no longer need to be told upfront about which URLs to expect, as IDs are generated from the domain id and document ordinal.

For now, we no longer store new URLs in different domains.  We need to re-implement this somehow, probably in a different job or a as a different output.

c70670bacb (common) New UrlIdCodec class
