I am not sure what you mean. Our cache will build automatically. It rebuilds when you save a form and the source data has changed, and isn’t already in the cache. This would normally happen in the background, but some servers are not configured to allow background building of the cache, so in those cases the form has to stay open whilst it builds. a message would appear to tell you this.
Every time a post is saved in the normal way (in the WordPress editor), WordPress triggers and action that our plugin uses to update the cache for just that post, so that too is automatic.
The only time it would not be automatic is if you saved a post or changes to a post in a different way. For example, using an import plugin, and sometimes if posts are made with custom front end data entry forms. We have this action (that has to be run after each post is saved by the import plugin):
https://searchandfilter.com/documentation/action-filter-reference/#update-cache-for-a-particular-post
For example, for WP All Import, in your (child) theme functions.php file you would use this code:
add_action('pmxi_saved_post', 'wp_all_import_post_saved', 1000, 1);
function wp_all_import_post_saved($id) {
do_action('search_filter_update_post_cache', $id);
}
.
