Need Help With String Method 'Contains' in Trigger

I have an Apex Trigger listed below, I need to change where it says Subject = 'Email Sent' or Subject = 'Email Received' to be Subject Contains Email, but I can seem to get it to work properly.
  
trigger SumEmailActivitesOnAccount on Task (after insert, after update, after delete) {

    set<Id> set_Id = new set<Id>();
   
    List<Account>acc_list = new List<Account>();
    
    if(Trigger.isInsert || Trigger.isUpdate) {
        for(Task T:Trigger.new){
            set_Id.add(T.WhatId);
        }

     }
    else if(Trigger.isDelete){
        for(Task T:Trigger.old){
            set_Id.add(T.WhatId);
        }

     }
     
    if(Trigger.isAfter && (Trigger.isUpdate || Trigger.isInsert || Trigger.isDelete)){
        acc_list=[SELECT Id, Sum_Email_Activities__c, (SELECT Id FROM Tasks WHERE Status = 'Completed' AND (Subject = 'Email Sent' or Subject = 'Email Received')) FROM Account WHERE Id IN :set_Id];

     for(Account acc: acc_list){
        if(acc.Tasks.size()>0)
            acc.Sum_Email_Activities__c = acc.Tasks.size();
        else
            acc.Sum_Email_Activities__c = 0;
     }
        if(!acc_list.isEmpty())
            update acc_list;
        }

}

In the SOQL you need to use LIKE operator and wild card character search for eg., the query will be something like:

acc_list=[SELECT Id, Sum_Email_Activities__c, (SELECT Id FROM Tasks WHERE Status= 'Completed' AND Subject  LIKE '%Email%') FROM AccountWHERE Id IN :set_Id]; // this gives you all records those contain Email in the subject.

Hope it helps.,

Thanks,

Balaji,

You always come through in the clutch, I was trying to use Contains(Subject, 'Email') But i think that is only usable in formulas and such. Thanks again for helping me solve thsi issue, works perfectly!
