• Highlighting search results

The example demonstrates a typical usage of the class.

 
 String indexFolder = "c:\\MyIndex\\";
 String documentsFolder = "c:\\MyDocuments\\";
 // Creating an index
 Index index = new Index(indexFolder);
 // Indexing documents from the specified folder
 index.add(documentsFolder);
 // Search for the word 'Einstein'
 SearchResult result = index.search("Einstein");
 // Assigning highlight options
 HighlightOptions options = new HighlightOptions();
 options.setTermsBefore(5);
 options.setTermsAfter(5);
 options.setTermsTotal(15);
 // Highlighting found words in the text of a document
 FoundDocument document = result.getFoundDocument(0);
 HtmlFragmentHighlighter highlighter = new HtmlFragmentHighlighter();
 index.highlight(document, highlighter, options);
 // Getting the result
 FragmentContainer[] fragmentContainers = highlighter.getResult();
 for (int i = 0; i < fragmentContainers.length; i++) {
     FragmentContainer container = fragmentContainers[i];
     String[] fragments = container.getFragments();
     if (fragments.length > 0) {
         System.out.println(container.getFieldName());
         System.out.println();
         for (int j = 0; j < fragments.length; j++) {
             // Printing HTML markup to console
             System.out.println(fragments[j]);
             System.out.println();
         }
     }
