The Relevanssi knowledge base is full of code snippets and custom functions that you can use to enhance your site and to change how Relevanssi works. But where to place those snippets and functions? There are many different methods of adding custom functions to your site, and I will go through them in this article.…
Relevanssi ignores HTML tags when indexing posts. If you want to give more weight to words that appear in specific HTML tags (like headings), here is one way to do that. You can add this filter function on your site to the theme functions.php or in a code snippet: This code goes through the post…
Relevanssi by default ignores image alt texts (and other tag attributes). That’s often the right thing to do because alt texts aren’t visible to users. Finding a post with a search term that only appears in an alt text may confuse a user. If your alt texts are well crafted, they may help search. It’s…
If Polylang is in use and you haven’t enabled “Media translation“, your attachment files won’t have a language. That’s fine, except when Relevanssi searches fail to find your attachment because they’re looking for posts in a specific language. Suppose you want to include attachments in Polylang searches. In that case, you can either enable “Media…
If you use PostX Pro to build a search results template using their Post Grid block, you’ll notice that the search results don’t work with Relevanssi enabled. If Relevanssi is active, you get no search results, and if Relevanssi is deactivated, results show up. This problem happens because PostX Pro uses WP_Query to fetch the…
Relevanssi Premium 2.16.0 is a major release that adds new, exciting features. The most interesting new tool is click tracking, which grants you extra insight into what the search users are doing. Some of these features are also available in the matching free Relevanssi version 4.14.0. The new User searches page should be a delight!…
WordPress doesn’t make adding a search form in the navigation menu easy. It’s a popular request, though, and having access to the search in the site header is typical. Relevanssi itself doesn’t have opinions on the user interface. Some themes, like Twenty Twenty, include a built-in search feature in the header. That’s a good reference…
If you want to use Relevanssi in the link queries (the search you get when adding links to posts in Classic editor), that’s easy. Make sure Relevanssi is enabled in admin searches, and then add this function: This function will make the Classic Editor link queries use Relevanssi. This approach generally works fine, but if…
CodeMirror Blocks is a good plugin for displaying good-looking code blocks in WordPress (you can see it in action right here on Relevanssi.com!). There’s a problem with Relevanssi in-document highlighting and the CodeMirror block, though: enabling the highlighting will break all CodeMirror blocks on the page, even if the highlighting happens outside the block. This…
With Advanced Custom Fields, sometimes Relevanssi picks up custom field names to include in the excerpts. This problem happens when you set Relevanssi to index all visible custom fields and have Flexible Content fields. Let’s assume there’s a Flexible Content field with the name flexible_content. It has a layout named field_layout, and in that layout,…
