Robert Muir commented on SOLR-3855:
-----------------------------------
Damn i hate our binary type. If it weren't for facets....
{code}
if (docValuesType != DocValuesType.SORTED && docValuesType !=
DocValuesType.BINARY) {
throw new SolrException(SolrException.ErrorCode.SERVER_ERROR,
"StrField only supports binary and sorted doc values");
}
{code}
<!-- Use this field type in conjunction with a field with doc values to sort
efficiently on a field which has a lot of unique terms. -->
<fieldType name="unique_string_sort" class="solr.StrField"
docValuesType="binary" />
{code}
Can we either:
# NOT suggest this and fix the check to only allow sorted values by default.
# fix getSortField() and getValueSource() to do the right thing and not call
FieldCache.getDocTermsIndex
Same goes with any other field types. Such insanity should be avoided :)

> It would be nice if Solr supported DocValues:
> - for ID fields (fewer disk seeks when running distributed search),
> - for sorting/faceting/function queries (faster warmup time than fieldcache),
> - better on-disk and in-memory efficiency (you can use packed impls).
