Hi Jessica,
Unfortunately I don’t think this is possible without major custom coding. If I udnerstnad correctly, you want to display the post contents within the result itself, but only when to user clicks on it. This is definitely not possible.
You can display the whole post contents by default, by making the following changes:
– Changing the primary content field to ‘Post content’
– Executing the shortcodes
– Increasing the content character sizes
These will allow displaying the full content within each result, but I am not sure if I can recommend these settings.
