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

1e6800565a (system) Remove EdgeId<T> and similar objects
They seemed like a good idea at the time, but in practice they're wasting resources and not really providing the clarity I had hoped.

9894f37412 (index) Implement new URL ID coding scheme.
Also refactor along the way.  Really needs an additional pass, these tests are very hairy.

e49b1dd155 Better handling of quote terms, fix bug in handling of longer queries.
... where some terms may previously have been ignored. The latter bug was due to the handling of QueryHeads with AnyOf-style predicates interacting poorly with alreadyConsideredTerms in SearchIndex.java

* Increase accuracy of the position bits.
* Increase their width to 56.
* Use a rolling position scheme for bits 16-56 to increase the average accuracy.
* Result ranking overhaul
* Optimized queries
* BM25 in the index service's ranking
* Make gui less jank
* Javadocs for ranking parameters.

dcf6218cdb Fix bugs related to search result selection in the case with multiple search terms.
* A deduplication filter step ran too early, and removed many good results on the basis that they partially, but did not fully fit another set of search terms.

* Altered the query creation process to prefer documents where multiple terms appear in the priority index.

46f81aca2f Break apart reverse index into a separate full index and priority index. It did this before using the same code. This will make the priority index about half as big since it no longer needs to keep metadata. 2023-03-21 16:12:31 +01:00
