Hi, I need help with code. The requirement is to display all the records of Contact that has Account. When I search, there is no results being displayed. Anything wrong with my custom controller? Just a reminder I've created a Wrapper Class for this dynamic Search.

Custom Controller:

public with sharing class AccountSearchSampleController{
    //Pagination variables
    public Integer pageCount = 0;
    public Integer currentPage = 1;
    public Integer pageLimit = 10;
    public Integer totalSize = 0;
    
    public String resultDateTime{get;set;}
    
    //Search Criteria fields variables
    public String AccountName {get;set;}	
    public String Country {get;set;}
    public String ContactName {get;set;}
    public String AccountType {get;set;}
    
    //Custom Setting variable class
    public Account_Filter__c searchSetting {get;set;}
    
    //Wrapper class
    public Map<Integer, List<ContactWithAccountWrapper>> accountSearchResultMap;

    //Constructor
    public AccountSearchSampleController(){
        //Initialize accountSearchResultMap to empty map
        this.accountSearchResultMap = new Map<Integer, List<ContactWithAccountWrapper>>();

        //Returns the custom setting data set record for the specified data set name.
        searchSetting = Account_Filter__c.getInstance();
        pageLimit = Integer.valueOf(searchSetting.Page_Limit__c);
    }     
    //For dynamic picklist of Account Type field
    public List<SelectOption> getAccountTypeOptionsList(){
        List<SelectOption> accountTypeOptionsList = new List<SelectOption>{new SelectOption('', '--None--')};
            Schema.DescribeFieldResult accountTypeDescription = Account.Type.getDescribe();
        List<Schema.PicklistEntry> accountTypePicklistValuesList = accountTypeDescription.getPicklistValues();
        for(Schema.PicklistEntry accountTypePicklistValue : accountTypePicklistValuesList){
            accountTypeOptionsList.add(new SelectOption(accountTypePicklistValue.getLabel(), accountTypePicklistValue.getValue()));
        }
        return accountTypeOptionsList;
    }

    //Displays error message method
    public Boolean checkFilterValidation(){
        Boolean valid = FALSE;
        
        if(this.Country	 != NULL){
            this.Country = this.Country.replace('*', '');
        }
        if(this.ContactName	 != NULL){
            this.ContactName = this.ContactName.replace('*', ''); 
        }
        Set<String> filterSet = new Set<String>{this.AccountName, this.Country, this.ContactName, this.AccountType};
            for(String filter : filterSet){
                if(!String.isBlank(filter)){
                    valid = TRUE;
                }
            }
        
        //Displays an error message if all fields does not have a value to search.
        if(!valid){
            ApexPages.Message errorMessage = new ApexPages.Message(ApexPages.Severity.ERROR, Label.LBL_Account_Search_No_Value);
            ApexPages.addMessage(errorMessage);
            return valid;
        }
        //Displays an error message if Account Name field does not have a value and should at least be 2 minimum characters to search.
        if(!String.isBlank(AccountName) && AccountName.length() < 2){
            ApexPages.Message errorMessage = new ApexPages.Message(ApexPages.Severity.ERROR, Label.LBL_Account_Search_Minimum_Character_Input);
            ApexPages.addMessage(errorMessage);
            valid = FALSE;
        }
        return valid;
