Relevanssi – A Better Search

Description

Relevanssi replaces the standard WordPress search with a better search engine, with lots of features and configurable options. You’ll get better results, better presentation of results – your users will thank you.

This is the free version of Relevanssi. There’s also Relevanssi Premium, which has added features. For more information about Premium, see Relevanssi.com.

Do note that using Relevanssi may require large amounts (hundreds of megabytes) of database space. If your hosting setup has a limited amount of space for database tables, using Relevanssi may cause problems. In those cases use of Relevanssi cannot be recommended.

Installation

  1. Install the plugin from the WordPress plugin screen.
  2. Activate the plugin.
  3. Go to the plugin settings page and build the index following the instructions there.
  4. That’s it!

Relevanssi uses the standard search form and doesn’t usually need any changes in the search results template.

If the search does not bring any results, your theme probably has a query_posts() call in the search results template. That throws Relevanssi off. For more information, see The most important Relevanssi debugging trick.

Uninstalling

To uninstall the plugin remove the plugin using the normal WordPress plugin management tools (from the Plugins page, first Deactivate, then Delete). If you remove the plugin files manually, the database tables and options will remain.

Knowledge Base

You can find solutions and answers at the Relevanssi Knowledge Base.

Contextual help

Answers to many common problems can be found from the contextual menu. Just click “Help” in the top right corner of your WordPress admin dashboard on the Relevanssi settings page.

Relevanssi doesn’t work

If you the results don’t change after installing and activating Relevanssi, the most likely reason is that you have a call to query_posts() on your search results template. This confuses Relevanssi. Try removing the query_posts() call and see what happens.

Searching for words with ampersands or hyphens doesn’t work

Please read Words with punctuation can’t be found. This is a Relevanssi feature, but you can fix it from Relevanssi indexing settings.

Where are the user search logs?

See the top of the admin menu. There’s ‘User searches’.

Displaying the relevance score

Relevanssi stores the relevance score it uses to sort results in the $post variable. Just add something like

echo $post->relevance_score

to your search results template inside a PHP code block to display the relevance score.

Did you mean? suggestions

Relevanssi offers Google-style “Did you mean?” suggestions. See “Did you mean” suggestions in the Knowledge Base for more details.

What is tf * idf weighing?

It’s the basic weighing scheme used in information retrieval. Tf stands for term frequency while idf is inverted document frequency. Term frequency is simply the number of times the term appears in a document, while document frequency is the number of documents in the database where the term appears.

Thus, the weight of the word for a document increases the more often it appears in the document and the less often it appears in other documents.

What are stop words?

Each document database is full of useless words. All the little words that appear in just about every document are completely useless for information retrieval purposes. Basically, their inverted document frequency is really low, so they never have much power in matching. Also, removing those words helps to make the index smaller and searching faster.

Reviews

Searches everything! Freely!

Using the free version ever since. Besides a lot of “built-in” standard features one can apply pre-made custom funcs and filters.

This helped me to having post content indexed and displayed in search that is actually hidden by a membership plugin (Memberpress).

So instead of just getting “0” search results, the plugin pulls out all the excerpts, titles and more. Visitors are getting a sense of what’s on my page which is more than crucial when searching for stuff.

All for free with Relevanssi. Great! And thanks!

Simply great

I should have installed this plugin months ago. So much more powerful and customizable than the WordPress search. Give it a go!

awesome plugin

Awesome plugin. Really surprised that WordPress hasn’t baked in some of these crucial features already, but thankfully we have a plugin like Relevanssi to come to the rescue. On top of that, the support is top notch. I had an issue where my theme wasn’t highlighting search queries in the page titles, and within 24 hours Relevanssi’s author gave me a custom php solution which solved the issue.

Excellent!

An awesome plugin, that turbo charges searching.

The author offered amazing support too!

Excellent Search Plugin

Relevanssi is without a doubt the best option for WordPress search plugins. Great amount of configurable options and unbeatable support.

Update Crashed My Site’s Updating/Editing or Adding

The new update 4.0.5 has crashed my wordpress website in sense that every time I update / Edit or add a new post (or anything) it crashes to page cannot be find. It does update or edit the post or page etc but I crash right after it.

Since this was the only plugin I updated today I deleted it and went back to the previous version for which I had to re-index and re do all the settings etc that I did when I 1st installed this plugin 🙁

The Previous version works ok for me at the moment so there clearly is a clash or a bug in this update.
