| Lucene Contrib Analyzers 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. |
