Tomás Fernández Löbbe updated SOLR-10835:
-----------------------------------------
Attachment: SOLR-10835.patch
Added a test for dates. Note that since SortedNumericDocValues doesn't
de-duplicate values, like SortedSet does, the behavior changes between
multiValued Trie* fields vs *Point fields if a document repeats the same value
more than once. [~joel.bernstein] you know this code better than me, do you
think this will cause problems with expressions?
> ExportWriter only works with TrieFooFields, not FooPointFields

> ExportWriter explicitly fails hard if you attempt to use it with any of the
> new Numeric Points based fields.
> The current failures come from explicit {{if (fieldType instanceof
> TrieFooField)}} checks in {{ExportWriter.getFieldWriters}} -- those could
> probably be replaced with {{instanceof FooValueFieldType}} (the numeric
> marker interfaces) or {{getNumericType()}} but i suspect in the multivalued
> case other problems will arise due to how ExportWriter dips into the guts of
> DocValues and assumes SortedSetDocValues
