Multiple conditions for a FilterExpression

 I am using Condition expression but I'm unable to add more than one condition to a FilterExpression.

My condition would be like

(En1_Name AND En2_LastName) AND (En1_NameAND En2_LastName)OR (En1_Name AND En2_LastName)

Sample of sql query would be like:

SELECT contact.fullname, account.address1_telephone1
        FROM contact
            LEFT OUTER/inner JOIN account   
WHERE (contact.address1_stateorprovince = 'WA' AND contact.address1_city ='Redmond'
 AND account.address1_telephone1 like '(206)%')
           OR
(contact.address1_stateorprovince = 'WA' AND contact.address1_city ='Redmond'
 AND account.address1_telephone1 like '(206)%')
     AND

(contact.address1_stateorprovince = 'WA' AND contact.address1_city ='Redmond'
 AND account.address1_telephone1 like '(206)%')

Please can any one help me.
