Nicholas Knize created LUCENE-6930: -------------------------------------- Summary: Decouple GeoPointField from NumericType Key: LUCENE-6930 URL: https://issues.apache.org/jira/browse/LUCENE-6930 Project: Lucene - Core Issue Type: Improvement Reporter: Nicholas Knize
{{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 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
