Lucene Snowball README file
|
|
|
|
This project provides pre-compiled version of the Snowball stemmers
|
|
based on revision 500 of the Tartarus Snowball repository,
|
|
together with classes integrating them with the Lucene search engine.
|
|
|
|
A few changes has been made to the static Snowball code and compiled stemmers:
|
|
|
|
* Class SnowballProgram is made abstract and contains new abstract method stem() to avoid reflection in Lucene filter class SnowballFilter.
|
|
* All use of StringBuffers has been refactored to StringBuilder for speed.
|
|
* Snowball BSD license header has been added to the Java classes to avoid having RAT adding new ASL headers.

IMPORTANT NOTICE ON BACKWARDS COMPATIBILITY!
|
|
|
|
An index created using the Snowball module in Lucene 2.3.2 and below
|
|
might not be compatible with the Snowball module in Lucene 2.4 or greater.
