David Smiley resolved LUCENE-5579. ---------------------------------- Resolution: Fixed Fix Version/s: 5.2 Lucene Fields: New,Patch Available (was: New) > Spatial, enhance RPT to differentiate confirmed from non-confirmed hits, then > validate with SDV > ----------------------------------------------------------------------------------------------- > > Key: LUCENE-5579 > URL: https://issues.apache.org/jira/browse/LUCENE-5579 > Project: Lucene - Core > Issue Type: New Feature > Components: modules/spatial > Reporter: David Smiley > Assignee: David Smiley > Fix For: 5.2 > > Attachments: LUCENE-5579_CompositeSpatialStrategy.patch, > LUCENE-5579_CompositeSpatialStrategy.patch, > LUCENE-5579_SPT_leaf_covered.patch, spatial.alg > > > If a cell is within the query shape (doesn't straddle the edge), then you can > be sure that all documents it matches are a confirmed hit. But if some > documents are only on the edge cells, then those documents could be validated > against SerializedDVStrategy for precise spatial search. This should be > *much* faster than using RPT and SerializedDVStrategy independently on the > same search, particularly when a lot of documents match. > Perhaps this'll be a new RPT subclass, or maybe an optional configuration of > RPT. This issue is just for the Intersects predicate, which will apply to > Disjoint. Until resolved in other issues, the other predicates can be > handled in a naive/slow way by creating a filter that combines RPT's filter > and SerializedDVStrategy's filter using BitsFilteredDocIdSet. > One thing I'm not sure of is how to expose to Lucene-spatial users the > underlying functionality such that they can put other query/filters > in-between RPT and the SerializedDVStrategy. Maybe that'll be done by simply > ensuring the predicate filters have this capability and are public. > It would be ideal to implement this capability _after_ the PrefixTree term > encoding is modified to differentiate edge leaf-cells from non-edge leaf > cells. This distinction will allow the code here to make more confirmed > matches. -- 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
