The query is quite short:

```edgeql
SELECT (Person.name, find(Person.name, 'ma'));
with names := (select (Person.name, find(Person.name, 'ma')))
select names.0 filter names.1 != -1;
```

Note that the first `Person.name` and the second `Person.name` are the same, which is why no Cartesian multiplication is used. However, if you changed the second one to `DETACHED Person.name` it would, and you would get well over 100 results.
