Reasonable expectations for Relevanssi searching speeds are measured in seconds. Relevanssi does not generally return results in milliseconds. On the other hand, the searches shouldn’t take more than few seconds in most cases. Multisite searches are a different thing: even if the searching is reasonably fast, searching across many sites will always be slow. Doing…
Sometimes it is helpful to have Relevanssi index the taxonomy term descriptions for posts. For example, the term description can be a good place to add alternate search terms for the term. By default, Relevanssi only indexes the term name, so you need extra code to get the term descriptions. The filter hook relevanssi_content_to_index is…
Versions 2.27.5 (Premium) and 4.24.4 (free) added extra security to highlighting search terms in post content. Before that, an attacker with contributor access could inject malicious content in the posts and the highlighting would then trigger that. This is now fixed, but the fix comes with a cost: the post content is passed through the…
It’s possible to integrate all kinds of external data to Relevanssi weights. Post Views Counter is an analytics plugin that collects stats about your visitors and stores them in the local database, which means those stats are available for Relevanssi. For some sites, this makes a lot of sense. For example, I have Kirjavinkit, a book review site…

Relevanssi Premium has tools for pinning posts for specific queries and all searches where the post appears, but what if you want to pin a post for all searches? That’s also possible but requires a bit of code. Pin the post for all searches and add this function to your site: Replace 1234 with the…
Aelia has a Prices by Country for WooCommerce plugin, which can adjust prices based on customer country and hide products unavailable in a specific country. Jason James shared a function that makes Relevanssi hide unavailable products in search: This function uses the relevanssi_post_ok filter hook to control which posts are included in the search and…
PublishPress Revisions causes duplicates to appear in Relevanssi search results when a revision is approved. When the revision is created, Relevanssi indexes it because it has the same post type as the original post with the post status draft. Relevanssi indexes drafts because people may want to search for them in the admin search. This is…
Korean has postpositions, which complicate things for Relevanssi. Fortunately, it’s easy to clean up the most common postpositions from the words. Add this function to your site: After you’ve added this function, rebuild the index. You also need to adjust the minimum word length to 2, as many Korean words are only two characters long.…
