Boosting shorter posts with higher keyword density

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…

WooCommerce: Return only exact matches for SKU searches

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. In order for this to work, Relevanssi must be set to index the _sku custom field…

Using phrases in Related posts searches

I have a book review site where I’m using Relevanssi Premium and the Related posts to highlight related book reviews. The reviews have multiple taxonomies used for the related posts: tags, book author, series, characters, and places. Messy relations The problem is, with the default settings, the Related posts get a bit messy. This site…

Indexing product codes with and without spaces

A Relevanssi Premium customer had a problem with product codes. The codes are in the format “ABC 100”, that is a group of letters and a group of digits with a space in between. Users may search for the codes without the space, so the post should be found with either “ABC 100” or “ABC100”.…

Partial matches to just one custom field

Is it possible to set (with filters and/or actions/functions) Relevanssi to use whole words keyword matching for post titles and 2 custom fields, and partial keyword matching only for a specific custom field (sku in this case)? Indeed it is! That is, you can’t set different keyword matching methods to different parts of the post,…

Excluding old content from the search

Is there a way to exclude anything before 2016 from search results? Yes. There are two approaches to this. If you never want to see anything old in the results, it’s best to filter in indexing with relevanssi_indexing_restriction. Add this to your site: Note that the restriction explains which posts are included in the index,…

Restrict search by author from the search query

You can set Relevanssi to index the post author, which will then let you find posts by searching for the name of the author. But what if you want a stricter filter? Where searching for an author would only show posts by that one author and nothing else? That’s possible too. Add this function to…

Restricting the search for non-logged-in users

There was an interesting support question: I have website with logged-in users as well as non-logged-in users. The logged-in user should be able to search through everything on the website, but the non-logged-in users should only be able to search the user profiles. Is it at all possible to differentiate the searches like this? The…

Blocking pre and code tags

If your posts have lots of programming code examples in <pre> and <code> tags, those might look pretty bad in the search results. A snippet of programming code isn’t usually a good excerpt, and if you use those tags purely for code snippets, they won’t likely contain significant search content, either. Fortunately it’s easy to…

Using AND and NOT for Boolean operators

Relevanssi Premium has support for in-query Boolean operators. Relevanssi uses + and – for the operators: cats -dogs and cats +kittens. If you prefer instead to use the verbal AND and NOT operators, it only takes one small function. Add this to your site: This function (on the relevanssi_search_filters hook) looks at the search query…
