# Russian Morphology for lucene
|
||||
|
||||
Russian and English morphology for java and lucene 3.0 framework based on open source dictionary from site [АОТ](http://aot.ru). It use dictionary base morphology with some heuristics for unknown words. It support homonym for example for Russian word "вина" it gives two variants "вино" and "вина".
|
||||
|
||||
|
||||
### How to use
|
||||
|
||||
First download
|
||||
[morph-1.0.jar](https://bintray.com/artifact/download/akuznetsov/russianmorphology/org/apache/lucene/morphology/morph/1.1/morph-1.1.jar)
|
||||
and add it to your class path. When download [Russian](https://bintray.com/artifact/download/akuznetsov/russianmorphology/org/apache/lucene/morphology/russian/1.1/russian-1.1.jar) or
|
||||
[English](https://bintray.com/artifact/download/akuznetsov/russianmorphology/org/apache/lucene/morphology/english/1.1/english-1.1.jar) package.
|
||||
|
||||
If you use maven you can add dependency
|
||||
|
||||
<dependency>
|
||||
<groupId>org.apache.lucene.morphology</groupId>
|
||||
<artifactId>russian</artifactId>
|
||||
<version>1.1</version>
|
||||
</dependency>
|
||||
|
||||
|
||||
<dependency>
|
||||
<groupId>org.apache.lucene.morphology</groupId>
|
||||
<artifactId>english</artifactId>
|
||||
<version>1.1</version>
|
||||
</dependency>
|
||||
|
||||
Don't forget add link to repository
|
||||
|
||||
|
||||
<repositories>
|
||||
...............
|
||||
<repository>
|
||||
<snapshots>
|
||||
<enabled>false</enabled>
|
||||
</snapshots>
|
||||
<id>bintray-akuznetsov-russianmorphology</id>
|
||||
<name>bintray</name>
|
||||
<url>http://dl.bintray.com/akuznetsov/russianmorphology</url>
|
||||
</repository>
|
||||
</repositories>
|
||||
|
||||
|
||||
|
||||
Now you can create a Lucene Analyzer
|
||||
|
||||
|
||||
RussianAnalayzer russian = new RussianAnalayzer();
|
||||
EnglishAnalayzer english = new EnglishAnalayzer();
|
||||
|
||||
|
||||
You can write you own analyzer using filter that convert word in it's right forms.
|
||||
|
||||
LuceneMorphology luceneMorph = new EnglishLuceneMorphology();
|
||||
TokenStream tokenStream = new MorphlogyFilter(result, luceneMorph);
|
||||
|
||||
Because usually LuceneMorphology contains a lot data needing for it functionality, it is better didn't create this object for each MorphologyFilter.
|
||||
|
||||
Also if you need get a list of base forms of word, you can use following example
|
||||
|
||||
|
||||
LuceneMorphology luceneMorph = new EnglishLuceneMorphology();
|
||||
List<String> wordBaseForms = luceneMorph.getMorphInfo(word);
|
||||
|
||||
|
||||
### Restrictions
|
||||
|
||||
* It works only with UTF-8.
|
||||
* It assume what letters е and ё are the same.
|
||||
* Word forms with prefixes like "наибольший" treated as separate word.
