Finding the position of search hits from Lucene

Question

With Lucene, what would be the recommended approach for locating matches in search results?

More specifically, suppose index documents have a field \"fullText\" whic

Answer 1

TermFreqVector is what I used. Here is a working demo, that prints both the term positions, and the starting and ending term indexes:

public class Search {
    public static void main(String[] args) throws IOException, ParseException {
        Search s = new Search();  
        s.doSearch(args[0], args[1]);  
    }  

    Search() {
    }  

    public void doSearch(String db, String querystr) throws IOException, ParseException {
        // 1. Specify the analyzer for tokenizing text.  
        //    The same analyzer should be used as was used for indexing  
        StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_CURRENT);  

        Directory index = FSDirectory.open(new File(db));  

        // 2. query  
        Query q = new QueryParser(Version.LUCENE_CURRENT, "contents", analyzer).parse(querystr);  

        // 3. search  
        int hitsPerPage = 10;  
        IndexSearcher searcher = new IndexSearcher(index, true);  
        IndexReader reader = IndexReader.open(index, true);  
        searcher.setDefaultFieldSortScoring(true, false);  
        TopScoreDocCollector collector = TopScoreDocCollector.create(hitsPerPage, true);  
        searcher.search(q, collector);  
        ScoreDoc[] hits = collector.topDocs().scoreDocs;  

        // 4. display term positions, and term indexes   
        System.out.println("Found " + hits.length + " hits.");  
        for(int i=0;i
