> See [this java-user discussion|http://www.nabble.com/lucene-farsi-problem-td16977096.html]
of problems caused by Unicode code-point comparison, instead of collation, in RangeQuery.
> RangeQuery could take in a Locale via a setter, which could be used with a java.text.Collator
and/or CollationKey's, to handle ranges for languages which have alphabet orderings different
from those in Unicode.
