Subject Re: [jira] Commented: (SOLR-1586) Create Spatial Point FieldTypes
Date Tue, 29 Dec 2009 19:25:07 GMT
Hmm, so it's faster to do 2 range searches than use the TermEnumerator to
find maybe 4-6 individual CartesianTier id's?

I had similar approaches in the past like 2 years ago, that just weren't
fast enough, and I've even published comparisons with Trie data types, and
find CartesianTier id's
https://issues.apache.org/jira/browse/SOLR-773?focusedCommentId=12708605&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12708605

The speed of Trie match what Ure's expectations were about 100ms, but
Cartesian is just 12ms.

The custom code, well you'd have to have custom code to figure out the
bounding box from a point, unless you want to user to figure that out?
And the Cartesian stuff is pretty small, it's underlying structure can / and
now does use Trie (simply because it's the only numeric field cache
interface common between lucene and solr).
