 Calling replace_document twice with the same key doubles the size of the
 database on disk (unexpected). However when running search only one
 document returned (expected). Subsequent replace_document calls do not
 change the database size(expected). This is the code to replicate:


 {{{

 <?php

 include "xapian.php";

 $value="thisistest";
 myreplace($value);
 passthru("ls -l replace.db");
 myreplace($value);
 passthru("ls -l replace.db");
 myreplace($value);
 passthru("ls -l replace.db");


 function myreplace($value)
 {
   try
   {
     // Open the database for update, creating a new database if necessary.
     $database = new XapianWritableDatabase("replace.db",
 Xapian::DB_CREATE_OR_OPEN);

     $indexer = new XapianTermGenerator();
     $stemmer = new XapianStem("english");
     $indexer->set_stemmer($stemmer);


         $doc = new XapianDocument();

         $doc->add_term("Q$value");

         $indexer->set_document($doc);
         $indexer->index_text($value);

         //$database->add_document($doc);
         $database->replace_document("Q$value", $doc);

     $database = Null;
   }
   catch (Exception $e)
   {
     print $e->getMessage() . "\n";
     exit(1);
   }
 }

 ?>

 }}}

 Output:
