title: Simple
---

The simple tokenizer is the default tokenizer in ParadeDB. This tokenizer splits on punctuation, whitespace, and lowercases all characters.

If no tokenizer is specified for a text field, the simple tokenizer is used.

```sql
-- The following statements are equivalent
CREATE INDEX search_idx ON mock_items
USING bm25 (id, description)
WITH (key_field='id');

CREATE INDEX search_idx ON mock_items
USING bm25 (id, (description::pdb.simple))
WITH (key_field='id');
```

To get a feel for this tokenizer, run the following command and replace the text with your own:

```sql
SELECT 'Tokenize me!'::pdb.simple::text[];
```

```ini Expected Response
     text
---------------
 {tokenize,me}
(1 row)
```
