Excellent, I just added it to my remix of your search app.
I also created a companion app so that anyone can grab the output of their posts without having to mess with the API, CURL or access tokens (here it is). All you need to do is remix @bugbuster’s app first, log in with your Write.as credentials on the companion app, copy the json it spits out, and paste it into the wa-posts.json file of your remixed search app. And to be safe, the companion app logs you out at the end, making the authentication token generated when logging in useless except for getting the json.
My hope is that this will make using the search app easier, especially for grabbing an updated list of all your posts to search from.
