I am implementing a book search function based on hibernate search3.2.

Book object contains a field called authornames. Authornames value is a list of names and comma is the splitter, say "John Will, Robin Rod, James Timerberland"

@Field(index = org.hibernate.search.annotations.Index.UN_TOKENIZED,store=Store.YES)
@FieldBridge(impl=CollectionToCSVBridge.class)
private Set<String> authornames;

I need each of names to be UN_TOKENIZED, so that user search book by single author name: John Will, Robin Rod or James Timerberland.

I used Luke to check indexs, and value in authornames field is stored as "John Will, Robin Rod, James Timerberland", but I can not get result by querying "authornames:John Will"

Anybody can tell me how can I do it?

Hi,
sorry for the delay. Just implement a FieldBridge which adds each element separately, not using commas to concatenate the string:

Code:
@Override
   public void set(String name, Object value, Document document, LuceneOptions luceneOptions) {
      if ( value == null ) {
         return;
      }
      if ( !( value instanceof Collection ) ) {
         throw new IllegalArgumentException( "This FieldBridge only supports collections." );
      }
      Collection<?> objects = (Collection<?>) value;

      for ( Object object : objects ) {
         luceneOptions.addFieldToDocument( name, objectToString( object ), document ); //objectToString depends on your type..
      }
   }
