Add a titlematch option to the API.
In ApiQueryAllPages.php I added
if ( isset( $params['titlematch'] ) ) {
$titleMatchString = $params['titlematch'];
$titleMatchStrings = explode("%", $titleMatchString);
$titleMatchString1 = $titleMatchStrings[0];
$titleMatchString2 = $titleMatchStrings[1];
$titleMatchString3 = $titleMatchStrings[2];
$this->addWhere( 'page_title' . $db->buildLike( $db->anyString(), $titleMatchString1, $db->anyString() ) );
if($titleMatchString2) $this->addWhere( 'page_title' . $db->buildLike( $db->anyString(), $titleMatchString2, $db->anyString() ) );
if($titleMatchString3) $this->addWhere( 'page_title' . $db->buildLike( $db->anyString(), $titleMatchString3, $db->anyString() ) );
}Usage: &aptitlematch=Foo / &aptitlematch=Foo%Bar / &aptitlematch=Foo%Bar%Baz
