| + | </code> | ||
| + | |||
| + | This method is used to investigate if each atom of the query is in all the counter models, because if it is not, it has to be removed from the query atoms. | ||
| + | |||
| + | **Parameters:** | ||
| + | * currentQueryAtoms - list of all the atoms that are inside the query | ||
| + | * counterModels - all the counter models found for the current query | ||
| + | * schema - database schema | ||
| + | |||
| + | **Returns:** | ||
| + | * list of atoms that are in all the counter models | ||
