Restricting the indexing to particular user roles

From the Relevanssi settings, you can only choose whether subscribers are indexed or not. If you need finer control over what user roles are indexed by Relevanssi, you can use the relevanssi_user_index_ok filter hook with the following code. Place it in your theme functions.php: Just adjust the $block_these_roles array to include the roles you want…

bbPress: Private Groups support

Private Groups is a plugin that makes bbPress forum groups private. Relevanssi, however, doesn’t understand that privacy and will show those groups in the search results. Relevanssi has means to support this, however, with the help of the relevanssi_post_ok filter. Here’s some code from Mark Wass that makes the private forum posts private in search.…

Utf8mb4 charset and index problems

If you use utf8mb4 charset, Relevanssi database table may be missing an index. That’s because part of the index includes a column type that is of varchar(210) type. This is fine with utf8, but fails for utf8mb4, which only allows columns 191 characters long (because maximum column size is 767 bytes, and for 4-byte utf8mb4…

Relevanssi Premium as a Composer package

If you want to install Relevanssi Premium as a Composer package, you can use the following URL to fetch the latest version: https://www.relevanssi.com/update/fetch_latest_version.php?api_key=XXX Replace XXX with your valid API key. The URL will always return the latest version of the plugin files. If you want a specific version, you can use the following: https://www.relevanssi.com/update/get_version.php?api_key=XXX&version=2.20.1 The…

Category filter for search results pages

Sometimes it’s nice to have a category filter on the search results pages: a simple dropdown where you can choose the category you want to show. It’s easy to create one using wp_dropdown_categories() but on a search results page, that’s slightly problematic, as it’ll include all categories, not just those included in the search results.…

Infinite Scroll from Jetpack

Jetpack has Infinite Scroll, which is a pretty cool feature, but unfortunately doesn’t work with Relevanssi on search results pages. Infinite Scroll uses WP_Query to get more posts, and that isn’t compatible with Relevanssi. I’m not aware of a solution that would allow Infinite Scroll to work with Relevanssi. There isn’t enough room for customization…

Adding extra boost for exact title matches

Every now and then, somebody wants to see exact title matches higher in the results. Usually, the best way to do this is to increase the title weight, maybe switch the default operator to AND and let the Relevanssi algorithm lift the best results. If that is not enough, you can use this code to…

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 the…

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…
