Uwe Schindler commented on SOLR-2976:
-------------------------------------
+1, please remove useless TrieTokenizer! The only backside is, that you can no
longer "inspect trie tokens" with AnalysisRequestHandler, but that's not really
an issue, because numeric terms are an implementation detail :-) I just used it
sometimes to demonstrate users how trie terms look like.
>From ElasticSearch I know that they also added this Tokenizer (Adrien did it),
>but there it was done for highlighting. If this is the case in Solr, too, we
>should keep it. How is highlighting affected - or does highölighting on
>NumericFields does not work at all in Solr?
> stats.facet no longer works on single valued trie fields that don't use
> precision step

> Key: SOLR-2976
> URL: https://issues.apache.org/jira/browse/SOLR-2976
> Project: Solr
> Issue Type: Bug
> Affects Versions: 3.5
> Reporter: Hoss Man
> Attachments: SOLR-2976_3.4_test.patch, SOLR-2976.patch,
> SOLR-2976.patch
>
>
> As reported on the mailing list, 3.5 introduced a regression that prevents
> single valued Trie fields that don't use precision steps (to add course
> grained terms) from being used in stats.facet.
> two immediately obvious problems...
> 1) in 3.5 the stats component is checking if isTokenzed() is true for the
> field type (which is probably wise) but regardless of the precisionStep used,
> TrieField.isTokenized is hardcoded to return true
> 2) the 3.5 stats faceting will fail if the FieldType is multivalued - it
> doesn't check if the SchemaField is configured to be single valued
> (overriding the FieldType)
> so even if a user has something like this in their schema...
> {code}
> <fieldType name="long" class="solr.TrieLongField" precisionStep="0"
> omitNorms="true" />
> <field name="ts" type="long" indexed="true" stored="true" required="true"
> multiValued="false" />
> {code}
> ...stats.facet will not work.
