--------------------------------------------

             Summary: Currently Lucene doesn't have an analyzer for Sinhala. We have built
analyzer which consist of language dependent tokenizer, stemming algorithm and list of stop
words.
                 Key: LUCENE-9044
                 URL: https://issues.apache.org/jira/browse/LUCENE-9044
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/analysis
    Affects Versions: 8.3
         Environment: Lucene
            Reporter: pavithra kariyawasam
             Fix For: 5.5.6
         Attachments: SinhalaAnalyzer.java, SinhalaStemmer.java, SinhalaTokenizer.java, stopwords.txt

This component is developed based on three main researches.
Lucene did not have component to analyze Sinhala documents. So our intension is to fill that
space with an Analyzer which can analyze Sinhala documents. Sinhala Analyzer has implemented
by performing Sinhala morphological analysis. Tokenizing the document content precisely, Removing
stopwords accordingly and converting the terms to its base/root form accurately are the main
three functionalities of Sinhala Analyzer. These are built by considering the grammatical
rules in Sinhala
