b09e2dbeb7 (build) Fix dependency churn from testcontainers
Apparently you need to pull in commons-codec now in order to run testcontainers, through spooky action at a distance.

a18edad04c (index) Remove stopword list from converter
We want to index all words in the document, stopword handling is moved to the index where we change the semantics to elide inclusion checks in query construction for a very short list of words tentatively hard-coded in SearchTerms.

f01267bc6b (index) Don't load fwd index offsets into a hash table at start.
This makes the service take forever to start up.  Memory map the data instead and binary search.  This is a bit slower, but not by much.

2080e31616 (converter) Store link text positions
To help offer verbatim matches for external link texts, we assign these positions in the document a bit after the actual document ends.  Integrating this information with the ranking is not performed here.

dc5c668940 (index) Re-enable parallelization of index construction, disable parallel sorting during construction
The first change, running index construction in parallel, was previously how it was done, but it was changed to run sequentially to see how it would affect performance.  It got worse, so the change is reverted.

Though it's been noted that sorting in parallel is likely not a good idea as it leads to a lot of I/O thrashing, so this is changed to be done sequentially.
