Michael McCandless commented on LUCENE-7314:
--------------------------------------------
bq. I mean... if we have spatial module(s), who would think to go looking in
core?
Hmm I see the situation reversed. I suspect new users would start with
Lucene's core, expecting to find usable defaults there for common use cases, as
we have done with our codecs. And only if they can't find what they need
there, would they say "hmm, where else can I look". We don't see users today
being confused that our best default codec is in core, not in the codecs
module. It just works :)
With {{LatLonPoint}} in core we would have javadocs there that point you to the
spatial/spatial-extras to do more expert things like shape indexing.
Experts can go digging through other modules, but the 90% use cases really
should be covered by core: simple things should be simple and complex things
should be possible.
I think this transition (putting a good default for a common use case in core)
is maybe also just a sign of enough maturity: spatial has gone through so many
iterations over the years, and I think finally this incarnation meets all the
right criteria to be a good core default. Really the addition of dimensional
points to Lucene's core already reflects this maturity.
In fact, I think there are other modules that have "matured" classes that would
make good defaults in core: {{StandardAnalyzer}} has progressed so much (it now
in fact does implement a Unicode "standard") that it is a great default
analyzer; {{SimpleQueryParser}} would be a great default; maybe
{{PostingsHighlighter}}, etc.
