Hi, Solr 4.7 is old but is probably okay. Is it easy to try a 6.x version? (note Spatial4j java package names have changed). There's also multiple new pertinent options to your scenario: https://locationtech.github.io/spatial4j/apidocs/org/locationtech/spatial4j/context/jts/JtsSpatialContextFactory.html * "useJtsMulti":"false" (defaults to true) * "useJtsLineString":"false" (defaults to true)
Any way, this could be due to the validationRule="repairBuffer0" logic if per chance the indexed shape isn't considered "valid" (by JTS). If flipping these options and using a recent Solr/Lucene/Spatial4j release don't fix the issue, please file a JIRA issue to the Lucene project.
