Examples of org.apache.lucene.index.MultiReader

org.apache.lucene.index.MultiReader
An IndexReader which reads multiple indexes, appending their content.

    addDoc("f123456", writer2);
    
    IndexReader ir1 = writer.getReader();
    IndexReader ir2 = writer2.getReader();
    
    MultiReader mr = new MultiReader(ir1, ir2);
    IndexSearcher searcher = newSearcher(mr);
    FuzzyQuery fq = new FuzzyQuery(new Term("field", "z123456"), 1, 0, 2, false);
    TopDocs docs = searcher.search(fq, 2);
    assertEquals(5, docs.totalHits); // 5 docs, from the a and b's
    mr.close();
    ir1.close();
    ir2.close();
    writer.close();
