[PATCH] arbitrary sorting


------- Additional Comments From cutting@apache.org  2004-02-10 22:32 -------
I don't think we ought to make this contingent on adding typed Fields to
Documents.  That's a big change, perhaps one that should eventually be made, but
I think we can easily make this change without going that far.

So I'd prefer there be a way to explicitly name the types when making the
search, rather than relying on pattern matching, perhaps something like:

  public abstract class SortField {
    public static final int SCORE = 0;     // sort by score
    public static final int DOC = 1;       // sort by doc number
    public static final int AUTO = 2;      // guess type of named field
    public static final int STRING = 3;    // sort by named field as String
    public static final int INT = 4;       // sort by named field as int
    pubilc static final int FLOAT = 5;     // sort by named field as float
  
    private String field;
    private int type = AUTO;
  }

  TopFieldDocs search (Query q, Filter f, int n, SortField[] sort_fields);

Would that work?
