[Plugin: Relevanssi – A Better Search] Remove ellipsis on custom excerpt

If you have Premium version, you have access to Premium version support. I suggest using that, as it gets you answers much faster.

So what exactly are you trying to achieve here? Do you want to add ACF Repeater field content so that it can be shown in excerpts? If so, I think all you need to do is to replace get_post_meta() from the sample code on Relevanssi.com with a has_sub_field() loop (see Template Code on ACF page).

If that is not what you want, please explain further what it is you want.
