```sql
CREATE VIRTUAL TABLE ""searchable_fts""
    USING FTS4 (text1, text2, [name with . and spaces], content=""searchable"")
```
OR like this:
```sql
CREATE VIRTUAL TABLE ""searchable_fts""
    USING FTS4 (text1, text2, [name with . and spaces], content=[searchable])
```
This fix looks to be correct to me (copying from the updated `test_with_trace()` test):

```python
            (
                ""SELECT name FROM sqlite_master\n""
                ""    WHERE rootpage = 0\n""

                ""            tbl_name = :table\n""
                ""            AND sql LIKE '%VIRTUAL TABLE%USING FTS%'\n""

                    ""like2"": '%VIRTUAL TABLE%USING FTS%content=""dogs""%',
                    ""table"": ""dogs"",
                },
            )

```python
@pytest.mark.parametrize(""reverse_order"", (True, False))

    table1, table2 = (""demo"", ""demo2"")
    if reverse_order:
        table1, table2 = table2, table1

    fresh_db[table1].insert({""title"": ""Hello""}).enable_fts(

    assert fresh_db[table2].detect_fts() == ""{}_fts"".format(table2)

The order matters - so this test currently passes in one direction and fails in the other:
```
>       assert fresh_db[table2].detect_fts() == ""{}_fts"".format(table2)

You're right, the code at fault is here:
