# Primary and Secondary title and description fields

![](/files/-L9ntY5hd-p3FPT_W9vb)

During the search post-process, the plugin parses the Post/Page/CPT titles and the contents, as defined by these fields. First it looks for the *Primary field*, and if it is not found or empty, it uses the *Secondary field.*

## Examples

### Custom field content as Title or Description

It is possible to define a single, text based custom field as the title or description field.

{% hint style="info" %}
 We recommend using it as the Primary field, so the plugin can fall back to a Secondary field, just in case.
{% endhint %}
