Re: Lucene GeoNear Search and Sort Performance

David, I was able to get it working with minor changes in my codebase. I didn't have back port PointVectorStrategy class from 6.6.0 to 5.5.4 Code: final int maxNumberOfCachedQueries = 256; final long maxRamBytesUsed = 50 * 1024L * 1024L; // 50MB final QueryCache queryCach

Re: Lucene GeoNear Search and Sort Performance

Hi David, Sorry I didn't inform my current environment setup. I am on Apache Lucene 5.5.4 version(As our application is still running on JDK 1.7). In that version, I only see one constructor for PointVectorStrategy class public PointVectorStrategy(com.spatial4j.core.context.SpatialContext c

Re: Lucene GeoNear Search and Sort Performance

Thanks for the suggestion. I changed the strategy to this.strategy = new PointVectorStrategy(ctx, "pointVector"); And the rest of the code remained same. I recreated the Index and while searching I am getting following Exception: Exception in thread "main" java.lang.IllegalStateException: une

Re: Lucene GeoNear Search and Sort Performance

Hi, Thanks for your suggestions that worked perfectly. But unfortunately our current application is still using JDK 1.7 and it would take a while to move to JDK 1.8. So I started using older version of Lucene 5.5.4 which supports 1.7, but its not working smoothly. I must be doing something wro

Re: Lucene GeoNear Search and Sort Performance

While Indexing, I am storing the following fields: doc.add(new StoredField("latitude", latitude)); doc.add(new StoredField("longitude", longitude)); doc.add(new LatLonPoint("loc", latitude, longitude)); As suggested, I added the following code:

Re: Lucene GeoNear Search and Sort Performance

For now, I used LatLonPoint.newDistanceQuery(...) and SloppyMath.haversinMeters to get the distance between center point and all other points within 50m radius circle and sort them using Comparator. I am able to get accurate results in < 10ms which is fine with me. Code: Query l

Re: Lucene GeoNear Search and Sort Performance

Thank you so much. With LatLonPoint.nearest(..), I am getting results in 6ms, with accurate results, when I compared MongoDB.geoNear(). I also tried with LatLonPoint.newDistanceQuery, and I got results in 6ms but the results are NOT the nearest points. Few more questions: Is there an API that u

Hi, I have similar requirement of searching points within a radius of 50m. Loaded 100M latlon, indexed/searching with LatLonDocValuesField. Currently, I am testing it on my macbook pro. I have tested with all Directory(RAM/FS/MMap) types, but it takes > 3-4 secs to do search/sort to return of
