RE: getLocale of SortField
Hi, it was not completely removed (it was intended to be removed). See the migration guide @ http://lucene.apache.org/core/4_3_1/MIGRATE.html, section about LUCENE-2514. The constructor and the logic was removed from SortField. The fast replacement (means sorting works as fast without collating) is to index the fields used for sorting with CollationKeyAnalyzer (https://lucene.apache.org/core/4_3_1/analyzers-common/org/apache/lucene/collation/CollationKeyAnalyzer.html). The Collator you get from e.g. the locale. The slow replacement (which is factored out from the old SortField stuff using the locale) is: http://lucene.apache.org/core/4_3_1/sandbox/org/apache/lucene/sandbox/queries/SlowCollatedStringComparator.html - use this class a custom sort comparator in your SortField. But be warned: It is horrible slow. The better was is, as mentioned before, to index the collated sort keys in the index and do a binary sort on the (non human-readable) keys.

So... one field dedicated for sorting per locale. Or at least per unique comparator (maybe multiple languages share sorting rules somewhere.) That seems like it could eat some space... I wonder if it couldn't just apply the collator when caching the values for sorting. Then it would all be in memory so it should work at the same speed as what's being done now.

You should look at at using the cool new Analysis features of Lucene 4.
