setserach.add (searchName);
Parameter : string
Account -Contact
Id IN : setId
ListContact accContactList =[select Id,AccountId from Contact where AccountId IN:[Select Id From Account]];
system.debug(accContactList.size());
ListAccount updateAccount= new ListAccount();
for(Account acc: [Select Name,phone,Fax, Industry, Rating,Billingcity From Account where Name =:searchName and phone=:searchphone])
