This is primarily to make the code a bit easier to reason about, and will reduce the level of indirection and data copying in the search-servi->query-service->index-service communication chain.
Quoted search queries that contained keywords with possessive 's endings were not returning any results, as the index does not retain that suffix, and the query parser was not stripping it away in this code path.
This solves issue #143.
Add a new rule that crates an alternative path that omits a word if it's a stopword.
In queries where a stopword is present, and no query ngram expansion is possible, the query should not require the stopword to be present in the index, as this results in no search results being found.
Seems to work, tests are green and initial testing finds no errors. Still a bit untested, committing WIP as-is because it would suck to lose weeks of work due to a drive failure or something.
Look, this will make the git history look funny, but trimming unnecessary depth from the source tree is a very necessary sanity-preserving measure when dealing with a super-modularized codebase like this one.
While it makes the project configuration a bit less conventional, it will save you several clicks every time you jump between modules. Which you'll do a lot, because it's *modul*ar. The src/main/java convention makes a lot of sense for a non-modular project though. This ain't that.
