Hi @exifi
I would check out our ACF-specific wiki page over at https://github.com/WebDevStudios/wp-search-with-algolia/wiki/Advanced-Custom-Fields for some examples of working with ACF based fields including a spot that shows how to add them as a snippet-based value.
The exact part of that page where the snippeting comes into play is https://github.com/WebDevStudios/wp-search-with-algolia/wiki/Advanced-Custom-Fields#make-custom-fields-searchable
Hope that helps.

Hi Michael, thanks for the reply.
To index the ACFs I did this and I see them correctly in Algolia.
function wds_algolia_custom_fields( array $attributes, WP_Post $post ) {
$fields = [
'payoff',
'descrizione_lunga',
'descrizione',
];
foreach ( $fields as $field ) {
$data = get_post_meta( $post->ID, $field );
$data = get_field( $field, $post->ID );
if ( ! empty( $data ) ) {
$attributes[ $field ] = $data;
}
}
return $attributes;
}
add_filter( 'algolia_post_shared_attributes', 'wds_algolia_custom_fields', 10, 2 );
add_filter( 'algolia_searchable_post_shared_attributes', 'wds_algolia_custom_fields', 10, 2 );
But now I have to show the content on the search page.
I would like to show an ACF for the description of a CPT. But if I show it with {{data.acf_field}} all the HTML comes out so I would like to try to show it as if it were the text snippet like data._snippetResult['content'].value
Thanks
Definitely understood, but you need to prepare your data a bit more to get that, which can be seen how with the link provided.
For example:
function my_posts_index_settings( array $settings ) {
$fields = [
'payoff',
'descrizione_lunga',
'descrizione',
];
foreach ( $fields as $field ) {
// If you want the fields searchable too, which makes sense.
$settings['searchableAttributes'][] = 'unordered(' . $field . ')';
// If you want the fields above to be added to the attributes to snippet.
// The "50" is the string character limit to cut things off at.
// @see https://www.algolia.com/doc/api-reference/api-parameters/#highlighting-snippeting
$settings['attributesToSnippet'][] = $field . ':50';
}
return $settings;
}
add_filter( 'algolia_posts_speaker_index_settings', 'my_posts_index_settings' );
This snippet will get all 3 ACF fields added to the searchable attributes, as well as add them into the snippet-ed portion.
After that, you’re going to need to modify the templates used (Documentation: https://github.com/WebDevStudios/wp-search-with-algolia/wiki/Customize-Templates ) and start making use of the snippet based property. For example: `data._snippetResult['descrizione'].value
If you need help verifying that the snippet version made it into index results, let me know where I can see the search in action, and I can check the Algolia results coming back in and all the available data to you.
Brief followup from my comment yesterday, the 50 is actually WORD count, not CHARACTER count. My apologies there.
Extra apologies due to copy/paste, I realized that the action hook used in my example is for a specific post type from our documentation.
You’d want to use 'algolia_posts_index_settings' for general/overall settings, or change out the speaker portion of the hook to a post type specific to your user case.
