I am trying to use a SOSL query where the criteria will be input from a text box on a VF page. I am running into a null pointer exception and struggling to figure out what it is. It is my first time using SOSL. So, I'm hoping the issue will be easy to spot.

public with sharing class mergeMaster {

	public string searchString {get; set;}
	public List<resultWrapper> wrappedResults {get; set;}
    
       
    //fired when the Search button is clicked
    public PageReference search() {
    	    	
    	List<List<SObject>> searchList = [FIND :searchString IN ALL FIELDS RETURNING CONTACT (Id, Name, Account.Name Order By Name) ];    	
    	
    	for(Contact reCon : (List<Contact>) searchList[0]) {    		
    		resultWrapper wrCon = new resultWrapper(reCon.Id, reCon.Name, reCon.Account.Name);
    		//system.assert(false,'Results: '+wrCon);
    		wrappedResults.add(wrCon);
    	}
    	
    	return null; 
    }  
  
    
    public class resultWrapper {
        public Id contactID {get; set;}
        public String contactName {get; set;}   
        public String accountName {get; set;}
        public List<SelectOption> masterORchild {get; set;}
        
        public resultWrapper(ID cID, String cName, String aName) {
            contactID = cID;
            contactName = cName;
            accountName = aName;
            this.masterORchild = new List<SelectOption>{new SelectOption('The Master','The Master'),new SelectOption('Merge','Merge')};
        }   
    }

}
