1.2 RC3
|
|
|
|
1. IndexWriter: fixed a bug where adding an optimized index to an
|
|
empty index failed. This was encountered using addIndexes to copy
|
|
a RAMDirectory index to an FSDirectory.
|
|
|
|
2. RAMDirectory: fixed a bug where RAMInputStream could not read
|
|
across more than across a single buffer boundary.
|
|
|
|
3. Fix query parser so it accepts queries with unicode characters.
|
|
|
|
4. Fix query parser so that PrefixQuery is used in preference to
|
|
WildcardQuery when there's only an asterisk at the end of the
|
|
term. Previously PrefixQuery would never be used.
|
|
|
|
5. Fix tests so they compile; fix ant file so it compiles tests
|
|
properly. Added test cases for Analyzers and PriorityQueue.
|
|
|
|
|
|
1.2 RC2, 19 October 2001:
|
|
- added sources to distribution
|
|
- removed broken build scripts and libraries from distribution
|
|
- SegmentsReader: fixed potential race condition
|
|
- FSDirectory: fixed so that getDirectory(xxx,true) correctly
|
|
erases the directory contents, even when the directory
|
|
has already been accessed in this JVM.
|
|
- RangeQuery: Fix issue where an inclusive range query would
|
|
include the nearest term in the index above a non-existant
|
|
specified upper term.
|
|
- SegmentTermEnum: Fix NullPointerException in clone() method
|
|
when the Term is null.
|
|
- JDK 1.1 compatibility fix: disabled lock files for JDK 1.1,
|
|
since they rely on a feature added in JDK 1.2.
|
|
|
|
1.2 RC1 (first Apache release), 2 October 2001:
|
|
- packages renamed from com.lucene to org.apache.lucene
|
|
- license switched from LGPL to Apache
|
|
- ant-only build -- no more makefiles
|
|
- addition of lock files--now fully thread & process safe
|
|
- addition of German stemmer
|
|
- MultiSearcher now supports low-level search API
|
|
- added RangeQuery, for term-range searching
|
|
- Analyzers can choose tokenizer based on field name
|
|
- misc bug fixes.

1.0, 2000-10-04
|
|
|
|

|
|
performance optimizations, a stemmer, and a few other minor
|
|
enhancements.

|
|
0.04 2000-04-19
|
|
|
|
Lucene now includes a grammar-based tokenizer, StandardTokenizer.
|
|
|
|
The only tokenizer included in the previous release (LetterTokenizer)
|
|
identified terms consisting entirely of alphabetic characters. The
|
|
new tokenizer uses a regular-expression grammar to identify more
|
|
complex classes of terms, including numbers, acronyms, email
|
|
addresses, etc.
|
|
|
|
StandardTokenizer serves two purposes:
|
|
|
|
1. It is a much better, general purpose tokenizer for use by
|
|
applications as is.
|
|
|
|
The easiest way for applications to start using
|
|
StandardTokenizer is to use StandardAnalyzer.
|
|
|
|
2. It provides a good example of grammar-based tokenization.
|
|
|
|
If an application has special tokenization requirements, it can
|
|
implement a custom tokenizer by copying the directory containing
|
|
the new tokenizer into the application and modifying it
|
|
accordingly.
|
|

|
0.01, 2000-03-30
|
|
|
|
First open source release.
|
|
|
|
The code has been re-organized into a new package and directory
|
|
structure for this release. It builds OK, but has not been tested
|
|
beyond that since the re-organization.
