Hello Scott,
I'm really sorry that delayed of this reply,
I have applied some fixes in your site, 
JoomlaFolder\plugins\search\easyblog\easyblog.php
LINE 137 until 155
			case 'exact':
				$where[]	= 'a.`title` LIKE ' . $db->Quote( '%'.$text.'%', false );
				$where[]	= 'a.`content` LIKE ' . $db->Quote( '%'.$text.'%', false );
				$where[]	= 'a.`intro` LIKE ' . $db->Quote( '%'.$text.'%', false );
				
				$where2		= '( t.title LIKE ' . $db->Quote( '%'.$text.'%', false ) . ')';
				$where 		= '(' . implode( ') OR (', $where ) . ')';

			case 'any':
			default:
				$words		= explode( ' ', $text );

				$where2		= array();

				{
					$word		= $db->Quote( '%'.$word.'%', false );
Replace with 
case 'exact':
				$where[]	= 'a.`title` LIKE ' . $db->Quote( '%'. $db->escape($text, true) .'%', false );
				$where[]	= 'a.`content` LIKE ' . $db->Quote( '%'. $db->escape($text, true) .'%', false );
				$where[]	= 'a.`intro` LIKE ' . $db->Quote( '%'. $db->escape($text, true) .'%', false );
				
				$where2		= '( t.title LIKE ' . $db->Quote( '%'. $db->escape($text, true) .'%', false ) . ')';
				$where 		= '(' . implode( ') OR (', $where ) . ')';
				break;
			case 'all':
			case 'any':
			default:
				$words		= explode( ' ', $text );
				$wheres		= array();
				$where2		= array();
				$wheres2	= array();
				
				foreach ($words as $word)
				{
					$word		= $db->Quote( '%'. $db->escape($word, true) .'%', false );
Thanks for reporting on this, we will including this fixes in next release version.
