By default, 'WITH USER_MODE' will be added when executing the query. If any fields or objects referenced in the query are inaccessible to the user, a QueryException is thrown. This can be disabled, if desired.

 // get user names where City starts with "San" (method chaining)
 User[] users = new aBoost.Query(User.SObjectType)
   .field(User.Name)
   .whereOp(User.City, 'LIKE', 'San%')
   .run();

 // get the number of contacts in Dallas accounts (complex query)
 aBoost.Query dallasAccounts = new aBoost.Query(Account.SObjectType)
   .whereOp(Account.City, '=', 'Dallas'));
 Integer contactCount = new aBoost.Query(Contact.SObjectType)
   .field(Contact.Name)
   .whereIn(Contact.AccountId, dallasAccounts)
   .count();

 // get the contacts in certain accounts (child query)
 Account[] results = new aBoost.Query(Account.SObjectType)
   .fields(new Query().createChildQuery(Contact.SObjectType, 'Contacts'))
   .whereIn(Account.Id, accounts)
