Uwe Schindler updated SOLR-2497:
--------------------------------
Attachment: SOLR-2497.patch
Patch applies to 3.2 branch only and needs the patch from LUCENE-3065 applied
before:
Here a first step in cutover of Solr to NumericField. Most tests work, except:
- TestDistributedSearch, fails with a strange date problem - I have no idea
what goes wrong
- TestMoreLikeThis: fails because the returned documents are different than
expected. The reason for this is simple: As TrieField's underlying Lucene
fields now are NumericField, stringValue() returns something (in contrast,
solr's old fields returned null because they were binary). This confuses maybe
MoreLikeThis (needs maybe fixed in Lucene, I havent looked into the code).
Maybe we should simply exclude those fields or fix the test (I prefer latter
one, because the numerics should also taken into account).
The following changes had to be made:
- Cut over all places in Solr where Field instead of abstract Fieldable is used
to Fieldable. This affects some leftover parts in various components (calling
Document.getField instead of Document.getFieldable), but mainly
SchemaField/FieldType: createField() now returns Fieldable
- TrieDateField code duplication was removed, all methods delegate to a wrapped
TrieField. There was also an inconsitency between TrieField and TrieDateField's
toExternal(). This was fixed to work correct (the date format was wrong, now it
uses dateField.toExternal())
If somebody could help with the rest of the solr stuff and maybe test test
test! Yonik? Ryan? There may be some itches not covered by tests.
Thanks for help from Solr specialists (I am definitely not one, I am more
afraid of the code than I can help)!!!

> This implements the changes to NumericField (LUCENE-3065) in Solr. TrieField
> & Co would use NumericField for indexing and reading stored fields. To enable
> this some missing changes in Solr's internals (Field -> Fieldable) need to be
> done. Also some backwards compatible stored fields parsing is needed to read
> pre-3.2 indexes without reindexing (as the format changed a little bit and
> Document.getFieldable returns NumericField instances now).
