# Advanced Search
From the mobile, it is possible to consult and download files available on the web.
## Configuration
To make this possible, choose a form (first level only) and the fields to make available in the search criteria by checking the option in each of them:
Then, **save** the form and start the [migration](/user-documentation/build/building-forms/migrations.md) if you want to search for existing submissions.
Field types available for search:
* Text
* Date
* List
* Number
* Boolean
* Email
* User
* Phone
* Formula
On the [custom app](/user-documentation/build/building-apps/app-configuration.md), add a **Search** button:
## Use on mobile
{% tabs %}
{% tab title="Android" %}
On the **Search** button, you will find a list of fields available for search, which have been previously checked in the form.
The search results can be downloaded on mobile and available on the **My Submissions** button.
Search criteria can be saved to redo the search later.
{% endtab %}
{% tab title="iOS" %}
On the **Search** button, you will find the same list of fields configured for search in the form. Tap a criterion to filter results, then download the matching submissions to your **My Submissions** list.
{% endtab %}
{% endtabs %}
