Excluding posts by taxonomy

Relevanssi has a category exclusion feature built in, but that only works for basic categories and not any other taxonomies. You can use tax_query to restrict the searches as well, but that’s more complicated than adjusting the setting in Relevanssi settings. However, if the exclusion is permanent, it’s best done in the indexing level. That […]

Issues with post order plugins

If you’re getting low quality results and the weight settings are not affecting the results, the first thing to check is to see if your results are coming from Relevanssi in the first place. That’s easy to check: disable Relevanssi and see if the results change. If the results change, they’re coming from Relevanssi. If […]

Deindexing Yoast SEO noindex posts

If you use Yoast SEO to mark posts “noindex”, you may want to have Relevanssi deindex those posts as well. It’s easy to do using the relevanssi_do_not_index hook. Just add this function to your theme functions.php: add_filter(’relevanssi_do_not_index’, ‘rlv_yoast_noindex’, 10, 2); function rlv_yoast_noindex($do_not_index, $post_id) { $noindex = get_post_meta($post_id, ‘_yoast_wpseo_meta-robots-noindex’, true); if ($noindex) $do_not_index = true; return […]

You can do it with this […]

Restricting Did you mean suggestions to one post type

Sometimes it may be necessary to restrict the Did you mean suggestions Relevanssi serves to just one post type. There’s no option for that, as by default the Relevanssi database the Did you mean suggestions use as a source (this only applies to Premium, that is) doesn’t have any information about the post types the […]

Results are in strange order

If best results don’t come up first and changing weighting settings doesn’t seem to make any difference, there couple of things you can do. Is Relevanssi active? The first thing is to check if the results are actually provided by Relevanssi. If you disable Relevanssi, do the results change? Do you see Relevanssi-generated excerpts? There […]
