A surprisingly common problem with Relevanssi is Bible verses. All that meaningful punctuation and single digits make exact matching of Bible verses really difficult for Relevanssi, and when searching for Bible verses, exact results are what matters – hitting something similar is generally not very helpful. There’s an easy solution, though: use phrases. Wrapping the verse…
If you have events on your site, you might not want to show the past events in the search. This is easy to do with Relevanssi. It can be done in two ways: either you block the past events in indexing or in searching. In most cases, the best solution is to do both. Blocking…
Relevanssi can automatically index PDF content for the parent post if the PDF (or other attachment) is attached to the parent post in WordPress. However, that’s not always the case. Sometimes the PDF is attached to the page using an embed, which doesn’t create a connection between the posts in WordPress. Thus, Relevanssi won’t know…
The Chamber Dashboard Business Directory plugin has a business directory search that’s not compatible with Relevanssi. To disable Relevanssi in those searches, add this to your theme functions.php: This will make the business directory search work again. However, I would recommend just using Relevanssi to search the business directory as well – that’s possible, and…
Related posts are a popular feature, as it keeps the users engaged and offers them a new direction to continue to within your site, keeping the users on your site for a longer time. Many plugins do related posts, but many have issues. Generating related posts can be a performance drain; the related posts may…
Total is a popular theme from WPExplorer. It mostly works fine with Relevanssi, with just one little issue. Total sets the post_type parameter for all searches to include all public post types. This is fine for most cases, but if you want to include user profiles or taxonomy terms in the search results, Total will…
By default, Relevanssi does not index HTML comments inside your posts. Relevanssi removes all HTML tags before indexing, and HTML comments (<!– like this –>) are counted as HTML tags. If you have content inside comments that you want to be indexed, you need to modify the punctuation control – which is responsible for removing…
Relevanssi works fine with Toolset, thanks to a lot of compatibility code the makers of Toolset have included in it to make it work with Relevanssi. However, everything doesn’t work automatically without modifications. The key thing to notice with Toolset is that query variables and filters don’t work the way you’d expect. Because of the…
By default, Relevanssi does not index the post slug. It is, however, an easy thing to fix using the relevanssi_content_to_index filter hook. This function will read the post slug, replace the hyphens with spaces (so that indexing-post-slugs becomes “indexing post slugs”) and add the slug to the post content. Add this function to your site…
Posts and pages on the product search results The Flatsome theme, when combined with WooCommerce, has a product search results page that can also show posts and pages. That doesn’t work with Relevanssi out of the box, but fortunately can be made to work. The function that adds the functionality is hooked in place, so…
