minimum similarity that is required for a term to match the query.
The QueryParser syntax for this is term~x, where x is a floating
point number >= 0 and < 1 (a bigger number means that a higher

- in case of compound file format has been improved.

- 7. Several methods and fields have been deprecated. The API documentation
- contains information about the recommended replacements. It is planned
- that the deprecated methods and fields will be removed in Lucene 2.0.

+ 6. A new class DateTools has been added. It allows you to format dates
in a readable format adequate for indexing. Unlike the existing
DateField class DateTools can cope with dates before 1970 and it
forces you to specify the desired date resolution (e.g. month, day,
second, ...) which can make RangeQuerys on those fields more efficient.

still somewhat slower than FSDirectory. However it uses less
memory per query term, since a new buffer is not allocated per

queries. It may also someday be faster. (cutting & Paul Elschot)

+
+ 1. Memory leak in Sort code (Bug# 31240) eliminated.

+
+ 2. The JSP demo page (src/jsp/results.jsp) now properly escapes error
+ messages which might contain user input (e.g. error messages about
+ query parsing). If you used that page as a starting point for your
+ own code please make sure your code also properly escapes HTML
