# New filter "isBlank" for text fields

[date: 2021-04-12T12:30:00.000+02:00]

To work around an ambiguity with empty text fields, especially with structured text fields, we have added a new `isBlank` filter for single-line text, multi-line text and structured text fields.

You can have a look at the details in the documentation page, [for example on the structured text](https://www.datocms.com/docs/content-delivery-api/filtering-records.md#structured_text).
