--------------------------------------
Summary: Improve GeoPointField type to only visit high precision
boundary terms
Key: LUCENE-6481
URL: https://issues.apache.org/jira/browse/LUCENE-6481
Project: Lucene - Core
Issue Type: Improvement
Components: core/index
Reporter: Nicholas Knize
Current GeoPointField [LUCENE-6450 |
https://issues.apache.org/jira/browse/LUCENE-6450] computes a set of ranges
along the space-filling curve that represent a provided bounding box. This
determines which terms to visit in the terms dictionary and which to skip. This
is suboptimal for large bounding boxes as we may end up visiting all terms
(which could be quite large).
This incremental improvement is to improve GeoPointField to only visit high
precision terms in boundary ranges and use the postings list for ranges that
are completely within the target bounding box.
A separate improvement is to switch over to auto-prefix and build an Automaton
representing the bounding box. That can be tracked in a separate issue.
