@ -313,6 +313,21 @@ LUCENE-1458, LUCENE-2111: Flexible Indexing
- o.a.l.analysis.StopwordAnalyzerBase -> o.a.l.analysis.util.StopwordAnalyzerBase
- o.a.l.analysis.WordListLoader -> o.a.l.analysis.util.WordListLoader
* LUCENE-2514: The option to use a Collator's order (instead of binary order) for
sorting and range queries has been moved to contrib/queries.
The Collated TermRangeQuery/Filter has been moved to SlowCollatedTermRangeQuery/Filter,
and the collated sorting has been moved to SlowCollatedStringComparator.
Note: this functionality isn't very scalable and if you are using it, consider
indexing collation keys with the collation support in the analysis module instead.
To perform collated range queries, use a suitable collating analyzer: CollationKeyAnalyzer
or ICUCollationKeyAnalyzer, and set qp.setAnalyzeRangeTerms(true).
TermRangeQuery and TermRangeFilter now work purely on bytes. Both have helper factory methods
(newStringRange) similar to the NumericRange API, to easily perform range queries on Strings.
* LUCENE-2691: The near-real-time API has moved from IndexWriter to
IndexReader. Instead of IndexWriter.getReader(), call
IndexReader.open(IndexWriter) or IndexReader.reopen(IndexWriter).
