Example #1 TokyoTyrantQuery::metaSearch() example

/* 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" } }
