Subject confused facet example
Date Tue, 30 Sep 2014 10:26:32 GMT
https://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_4_8/lucene/demo/src/java/org/apache/lucene/demo/facet/SimpleFacetsExample.java

In SimpleFacetsExample,

/** Runs the search example. */
  public List<FacetResult> runFacetOnly() throws IOException {
    index();
    return facetsOnly();
  }

  /** Runs the search example. */
  public List<FacetResult> runSearch() throws IOException {
    index();
    return facetsWithSearch();
  }

  /** Runs the drill-down example. */
  public FacetResult runDrillDown() throws IOException {
    index();
    return drillDown();
  }

  /** Runs the drill-sideways example. */
  public List<FacetResult> runDrillSideways() throws IOException {
    index();
    return drillSideways();
  }

  /** Runs the search and drill-down examples and prints the results. */
  public static void main(String[] args) throws Exception {
    System.out.println("Facet counting example:");
    System.out.println("-----------------------");
    SimpleFacetsExample example1 = new SimpleFacetsExample();
    List<FacetResult> results1 = example1.runFacetOnly();
    System.out.println("Author: " + results1.get(0));
    System.out.println("Publish Date: " + results1.get(1));

    System.out.println("Facet counting example (combined facets and search):");
    System.out.println("-----------------------");
    SimpleFacetsExample example = new SimpleFacetsExample();
    List<FacetResult> results = example.runSearch();
    System.out.println("Author: " + results.get(0));
    System.out.println("Publish Date: " + results.get(1));

    System.out.println("\n");
    System.out.println("Facet drill-down example (Publish Date/2010):");
    System.out.println("---------------------------------------------");
    System.out.println("Author: " + example.runDrillDown());

    System.out.println("\n");
    System.out.println("Facet drill-sideways example (Publish Date/2010):");
    System.out.println("---------------------------------------------");
    for(FacetResult result : example.runDrillSideways()) {
      System.out.println(result);
    }
  }


The example doesn't new SimpleFacetsExample each time.

So in drill-down example, it indexes 2 times, the result number is 2 times.
in drill-sideways example. it indexes 3 times, the result number is 3 times.

Is it intended?
