高级搜索Java库

Question

I am adding functionality of advanced search to JSF Based CMS product

Search criteria :

If User Searches with keyword Assets then he should be able to get records containing Asset As well as Assets

I found that Lucene and Solr are the best way to do full text search out of which I had implemented Apache Lucene Search which does work fast than normal Query result but does not solve my Search criteria.

Is there any other Java Library which will help me in this criteria ?

PorterStemmer is a good choice for supporting this sort of stemming in Lucene. Particularly, incorporating a PorterStemFilter into your Analyzer would be the typical approach. There is a simple example of that listed on the PorterStemFilter documentation linked, but may look something like (based on the StandardAnalyzer, in this case):

class MyStemmerAnalyzer extends Analyzer {
    @override
    public TokenStream tokenStream(String fieldName, Reader reader) {
        TokenStream stream = new StandardTokenizer(reader);
        stream = new StandardFilter(stream);
        stream = new LowerCaseFilter(stream);
        stream = new PorterStemFilter(stream);
        stream = new StopFilter(stream, StopAnalyzer.ENGLISH_STOP_WORDS_SET);
        return stream;
    }
}
