Yonik Seeley commented on LUCENE-1673:
--------------------------------------
bq. This will apply to int/long/float/double as well right? How would you do
this (require a parser for only numeric sorts) back-compatibly? EG, the others
(String, DOC, etc.) don't require a parser.
Allow passing parser==null to get the default?
bq. We could alternatively make NumericSortField (subclassing SortField), that
just uses the right parser?
A factory method TrieUtils.getSortField() could also return the right SortField.

> TrieRange was iterated many times and seems stable now (LUCENE-1470,
> LUCENE-1582, LUCENE-1602). There is lots of user interest, Solr added it to
> its default FieldTypes (SOLR-940) and if possible I want to move it to core
> before release of 2.9.
> Before this can be done, there are some things to think about:
> # There are now classes called LongTrieRangeQuery, IntTrieRangeQuery, how
> should they be called in core? I would suggest to leave it as it is. On the
> other hand, if this keeps our only numeric query implementation, we could
> call it LongRangeQuery, IntRangeQuery or NumericRangeQuery (see below, here
> are problems). Same for the TokenStreams and Filters.
> # Maybe the pairs of classes for indexing and searching should be moved into
> one class: NumericTokenStream, NumericRangeQuery, NumericRangeFilter. The
> problem here: ctors must be able to pass int, long, double, float as range
> parameters. For the end user, mixing these 4 types in one class is hard to
> handle. If somebody forgets to add a L to a long, it suddenly instantiates a
> int version of range query, hitting no results and so on. Same with other
> types. Maybe accept java.lang.Number as parameter (because nullable for
> half-open bounds) and one enum for the type.
> # TrieUtils move into o.a.l.util? or document or?
> # Move TokenStreams into o.a.l.analysis, ShiftAttribute into
> o.a.l.analysis.tokenattributes? Somewhere else?
> # If we rename the classes, should Solr stay with Trie (because there are
> different impls)?
> # Maybe add a subclass of AbstractField, that automatically creates these
> TokenStreams and omits norms/tf per default for easier addition to Document
> instances?
