Additional queries (some may have caveats or limitations)
The Java Sandbox RegexQuery family is not included in this package because it
was superseded by RegexpQuery in the main Lucene search package. Use
Lucene.Net.Search.RegexpQuery for regular-expression queries instead.
The deprecated SlowCollated query types are also not included. For indexed
collation keys, use CollationKeyAnalyzer or ICUCollationKeyAnalyzer from
the analysis packages. These replacements are supported alternatives to the
old Sandbox types and avoid carrying forward APIs that were removed upstream.
