We have posts with titles like “A perfect match”. If a user searches for this exact title, only this post should show up in the results. Otherwise, the search should run as default. There are several approaches to this, but the best is relevanssi_hits_filter. This function goes through all the posts, checks if the post…
If you want to add an option to search only in titles to your search form, here’s how. First, you need to modify the search form to add the selection. To add a simple dropdown, add this to your search form: This select element will create a small dropdown with the option to search everything…
It’s possible to integrate all kinds of external data to Relevanssi weights. Koko Analytics is a great analytics plugin. It 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…
By default, Relevanssi returns all posts when searching without a search term. That’s the default WordPress behaviour. Sometimes it may not be the wanted behaviour. One reason is performance: returning all results can be very slow. To stop Relevanssi from running when there’s no search term, add this to your site: This little function will…
WordPress doesn’t make it easy to add a search form in the navigation menu. 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 come with a built-in search feature in the header, like Twenty Twenty. That’s…
I set up a short coded search box to search my Learndash e-course for one specific category only: [ searchform ld_topic_category=”156″ ] It works perfectly except one thing: if no results show, it takes you to the default WordPress page and presents you with the standard search box that no longer searches category 156. This…
Relevanssi by default does not consider the search query a phrase, or value posts where the words in the search query appear together. Sometimes people do expect that, especially in AND searches. Relevanssi however does not have the information about the nearby words, so it’s not possible for Relevanssi to factor that in. Relevanssi does…
Relevanssi Premium 2.11 introduces a new feature: multi-part excerpts. There’s a new setting on the Excerpts & Highlights settings tab, “Number of excerpt snippets”, and that lets you define the maximum number of excerpt snippets Relevanssi generates for each post. How does it work This option is only available when the excerpt length is defined…
By default, Relevanssi tends to prefer longer posts. The default TF × IDF weights Relevanssi uses simply count the term frequency, ie. how many times a word appears in the post. That prefers longer posts as they usually have the search term appear more often. However, a 500-word post with 15 search term appearances might…
This little filter function works on relevanssi_hits_filter. When a search query is made that matches an SKU (or any other custom field, but SKUs are the most likely scenario here), only results that match the SKU will be returned. For this to work, Relevanssi must be set to index the _sku custom field (because otherwise,…
