ASF subversion and git services commented on LUCENE-6930: --------------------------------------------------------- Commit 74a08c08006941b74eda585b86b57fbe0ff341b2 in lucene-solr's branch refs/heads/branch_5x from nknize [ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=74a08c0 ] LUCENE-6930: Decouples GeoPointField from NumericType by using a custom GeoPointTokenStream and TermEnum designed for GeoPoint prefix terms > Decouple GeoPointField from NumericType > --------------------------------------- > > Key: LUCENE-6930 > URL: https://issues.apache.org/jira/browse/LUCENE-6930 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/spatial > Reporter: Nicholas Knize > Fix For: 5.5, trunk > > Attachments: LUCENE-6930.patch, LUCENE-6930.patch, LUCENE-6930.patch, > LUCENE-6930.patch, LUCENE-6930.patch, LUCENE-6930.patch > > > {{GeoPointField}} currently relies on {{NumericTokenStream}} to create prefix > terms for a GeoPoint using the precision step defined in {{GeoPointField}}. > At search time {{GeoPointTermsEnum}} recurses to a max precision that is > computed by the Query parameters. This max precision is never the full > precision, so creating and indexing the full precision terms is useless and > wasteful (it was always a side effect of just using indexing logic from the > Numeric type). > Furthermore, since the numerical logic always stored high precision terms > first, the recursion in {{GeoPointTermsEnum}} required transient memory for > storing ranges. By moving the trie logic to its own {{GeoPointTokenStream}} > and reversing the term order (such that lower resolution terms are first), > the GeoPointTermsEnum can naturally traverse, enabling on-demand creation of > PrefixTerms. This will be done in a separate issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
