Subject Re: [jira] Commented: (SOLR-773) Incorporate Local Lucene/Solr
Date Thu, 18 Sep 2008 13:28:12 GMT
Does Geohash enable range based queries?  It's unclear from the wiki site.

Can we do something like this  I
would rather see SOLR go in the direction of being compatible with
GData and GBase and invent more unique things, unless they are better

GBase has a notation for doing function queries as well that we should
build into SOLR, current SOLR function queries really are very
non-intuitive for me and I spend a lot of time each time trying to
figure out how to do them.

Check this stuff out.  I'm
not sure we need to create something quite this complex.  However, I
would like a way to do something like this without having to reboot
the server.  I personally thing this is best implemented using dynamic
classloading.  If people find that interesting, then we could look at
scripting.  I'm not a big fan of scripting because it's not object
oriented, it's not maintainable, scripts always grow and get too
complex to read so that when new people take a look at it the ramp up
time is high.  With dynamic classes, all of the functionality of what
is available is there.  No need to create new script functions, test
them out, load them, fix bugs and all that.

the local lucene stuff uses two fields and [|]
to index/store the distance.  It does a lot of good work to break various bounding box levels
into tokens and only performs math on the minimum result set.

lucene.  In particular, checking if a point is within a bounding box is simply a lexicographic
range query.
