[jira] [Updated] (SOLR-8396) Investigate PointField to replace
NumericField types
[ https://issues.apache.org/jira/browse/SOLR-8396?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tomás Fernández Löbbe updated SOLR-8396:
----------------------------------------
Attachment: SOLR-8396.patch
New patch:
* Added some errors when using point fields for unsupported cases (e.g. when faceting on a point field with no doc values). For now I'm considering those bad requests, but I don't know if we'll be able to consider all invalid cases and error gracefully, cases like FunctionQueries may not be easy (currently for faceting on a function query that has a point field with no DV will be a 500 for example, and the error is an IllegalStateException by Lucene).
* Grouping still doesn't work with PointFields.
* Added some more test coverage by making the test schema.xml use point fields. I plan to also add this to other test schemas when applicable. Ideally tests would randomly use "Legacy" or "Point" when dv=true
* Since field boost is not supported, right now I'm throwing an exception if used, but this makes index-time document boosting practically useless, so I think I should change the exception to a log message only and just omit the boost.
* Still only for int fields, lots of nocommits and a code refactor required

> In LUCENE-6917, [~mikemccand] mentioned that DimensionalValues are better than NumericFields in most respects. We should explore the benefits of using it in Solr and hence, if appropriate, switch over to using them.
