TokyoTyrantQuery::metaSearch() example

<?php
/* Connect to a table database */
$tt = new TokyoTyrantTable("localhost", 1979);
 
/* Add test data */
$tt->put('cherry',     array('color' => 'red'));
$tt->put('strawberry', array('color' => 'red'));
$tt->put('apple',      array('color' => 'green'));
$tt->put('lemon',      array('color' => 'yellow'));
 
/* First query */
$query = $tt->getQuery();
$query->addCond('color', TokyoTyrant::RDBQC_STREQ, 'red')->setOrder('color', TokyoTyrant::RDBQO_STRASC);
 
/* Second query */
$query1 = $tt->getQuery();
$query1->addCond('color', TokyoTyrant::RDBQC_STREQ, 'yellow');
 
/* Get union between the queries */
var_dump($query->metaSearch(array($query1), TokyoTyrant::RDBMS_UNION));
?>

The above example will output:

array(3) {
  ["cherry"]=>
  array(1) {
    ["color"]=>
    string(3) "red"
  }
  ["strawberry"]=>
  array(1) {
    ["color"]=>
    string(3) "red"
  }
  ["lemon"]=>
  array(1) {
    ["color"]=>
    string(6) "yellow"
  }
}
