 This type of classes responsible for collectiong items based on different conditions.
 To prevent lookup methods in models like this:

 Better use this: 
-```

-
-issues = selector.execute(project, user, filter)
+```ruby
+issues = IssuesFinder.new.execute(project, user, filter)
 ```
 It will help keep models thiner
