Hi Boenobo,
Thanks for reaching out to us! Unfortunately we are not able to provide support in the pre-sales forum 🙁
We are happy to assist our premium users with support issues via our premium forums, please log into the account that has been created when the purchase was made. If you have not purchased one of our premium plugins, you can post in our open source forum. We review that forum weekly, mainly for bug reports.
Just to give you a quick answer, default site search (I guess Avada doesn’t customize it) and even calendar search use the standard WordPress search function. This functions looks for the searched term in the ‘post title’ and ‘post content’ fields, not in associated post meta. One quick workaroun is to include the zip inside the event (or post) content.
I’ll go ahead and close out this thread, but please do post in the appropriate forum and we will be happy to assist you.
Best,
Nico
