(HibernateSearch) MultiFieldQueryParser for each field

Question

Some of my indexed fields use a Greek parser, and I want to use an English parser for some other fields. My problem is this: when searching for results (currently in MultiFieldQueryParser), how can I use a different parser for each field, so that the Greek parser is used for indexes with a Greek index, and English is used for indexed fields? / P>

Answer 1

You can create your query parser as follows:

Analyzer analyzer = fullTextSession.getSearchFactory().getAnalyzer(Item.class);
QueryParser parser = new MultiFieldQueryParser(Version.LUCENE_31, fields, analyzer);

, Item:

@Field(name = "greekTitle" analyzer = @Analyzer(impl = GreekAnalyzer.class))
public void getGreekTitle(){
 //...
}

@Field(name = "englishTitle" analyzer = @Analyzer(impl = StandardAnalyzer.class))
public void getEnglishTitle(){
 //...
}

Answer 2

, . .

transaction.begin();

PerFieldAnalyzerWrapper wrapper = new PerFieldAnalyzerWrapper(new StandardAnalyzer(Version.LUCENE_30));

wrapper.addAnalyzer("greekTitle", new GreekAnalyzer(Version.LUCENE_30));
wrapper.addAnalyzer("greekDescription", new GreekAnalyzer(Version.LUCENE_30));

String[] fields = {"greekTitle", "greekDescription", "englishTitle", "englishDescription"};

QueryParser queryParser = new MultiFieldQueryParser(Version.LUCENE_30, fields, wrapper);
queryParser.setDefaultOperator(QueryParser.AND_OPERATOR);
org.apache.lucene.search.Query query = queryParser.parse(QueryParser.escape(queryString));

javax.persistence.Query persistenceQuery = 
fullTextEntityManager.createFullTextQuery(query, Item.class);

@SuppressWarnings("unchecked")
List<Item> result = persistenceQuery.getResultList();

transaction.commit();

return result;
