WP FullText Search – The Power of Indexed Search


This plugin extends the standard search capabilities of WordPress by creating a transparent word-based index. This allows you to quickly search not only by the title and content of posts, but also by meta-fields, custom types of posts, and even by the contents of the attached files. Yes, all this is possible!

WPFTS does not require the installation of external indexing software and therefore works even on shared hostings. It does not require any refinement of your site, thus all other plugins will also automatically use the word-based index after installing the WPFTS.

You will be able to justify the relevance function by specifying the weights for the title, the content, and each of the meta-fields in your posts.

Unlike other search plug-ins, WPFTS does not replace the standard WP search, instead, it significantly expands its functionality. Thus, all built-in functions of WP_Query are saved, in addition, other plug-ins begin to use advanced search automatically.

There is a built-in Live Search functionality. You can simple switch it ON simple by using WPFTS’s native flexible Search Widget.

The extended (pro) version of the plugin allows you to automatically index the text content of the attached files (for example, PDF files, full list of supported files is listed in Documentation) and perform a quick search on them.

Here is a short summary of capabilities in this FREE version:

  • TRUE indexed text search within title, content, meta values or programmatically-created text data
  • Dramatically extends the native WordPress search (works via WP_Query())
  • Supports sentence search (do NOT requires touching words or strict word ordering)
  • Supports multisite
  • Supports powerful index clustering system (to assign different relevance weights to different parts of the post)
  • Supports AND and OR logic
  • Ordering results by relevance, date, post ID, title, slug, type, random, comment_count
  • Does not require 3rd-party libraries or services
  • Displays search results like Google does (it shows sentences with queried words and highlighting them)
  • Supports Live Search (you can see the list of search results right in the search input box!)
  • Works well on shared hostings
  • Supports language translations (English, Deutch, Russian and Ukrainian are ready now)
  • Dramatically extends native WP search (not replaces it)
  • Removes HTML tags and comments from post content before indexing it (useful for Gutenberg-driven sites)
  • Search full-text with TRUE relevance (using TF-IDF algorithm)
  • Relevance formula can be justified via settings (post title, content and each meta field can have different weights)
  • Make default search WP ordering configurable (very useful for WP site search via ?s=)
  • It has API and full documentation to customize plugin’s behaviour
  • Works well with PHP 5.6+ to PHP 7.4+

Please note, the PRO version of this plugin also supports:

  • File attachments search by their content (PDF, DOC, DOCX and other files currently supported)
  • Filter file search by filetype
  • Display file content in search results using Smart Excerpts
  • External service to extract text information from files can be used (license included)
  • Technical support (with installing, configuring, fixing conflicts)
  • Regular automatic updates (it works the same way as WP repository updates)
  • A bunch of add-ons which makes it possible to index and search the content and files generated by other plugins and themes (for example: file search add-on for WordPress Download Manager plugin, add-on for Filebase Pro, add-on for Delicious Downloads, and many more). Pro user may ask us to build a custom add-on for their own websites.

The plugin is simply excellent in enabling searches for pretty much any term (including custom taxonomies and metadata), while support is fast, positive, and helpful.

If I could give this 10 stars I would! This is truly one of the best value plugins I have seen in all my time using WordPress! First - for the ROI on price, the functionality you get is amazing! The ability to search through documents and be presented with the results is fantastic! We have archives of documents that were not indexable until now. Setting this up was a matter of installing, and clicking a few buttons. It could not be any easier. Next - In truth, I did run into some issues on the site I installed this on. However, the issues were due to poor coding on a custom theme. I inherited a site and the results I expected were not shown. Support from the developer was better than top-notch! Getting updated code, online chat, and support, and getting hotfixes blew away any expectations I had. I could not have asked for better support. In fact, unless he was sitting at my desk next to me, I cannot imagine better support. This plugin will be going on every site we use!!
