First, you need to ensure that the user id is being added to the document in the index in a field when you index, let's call it user_id.
In a pinch, you can add a field to the query string entered by the user behind the scenes before you send it to the query parser. So, take whatever query was entered and add " AND user_id:4" (where 4 is the value of the variable containing the current user id) onto the end of it.
