Redisearch implements a search engine on top of Redis. It has lots of advanced features, like exact phrase matching and numeric filtering for text queries, that are nearly not possible or inefficient with mysql search queries.
<h3>IMPORTANT</h3>
The latest version of this plugin supports RediSearch version 2.0 (or higher) which runs on Redis 6.0 (or higher). If you have version prior to 2.0, please use this plugins 0.2.7.
Here you find a list of RediSearch features included in the plugin:
Search: Instantly find the content you’re looking for. The first time.
Scoring fields differently: Give different score to different fields. For example higher score to product name and number than its description.
Fuzzy Search: Don’t worry about visitors misspelling.
Autosuggest: Adds a suggestion string to an auto-complete suggestion dictionary.
Synonyms: RediSearch supports synonyms, that is searching for synonyms words defined by the synonym data structure.
<h3>Existing features</h3>
<ul>
<li>WooCommerce: Index and search through most of existing products meta data.</li>
<li>Document: Index content of binary files such as pdf, word, excel and powerpoint.</li>
<li>Synonym: Adding synonym groups is simple. Just add each comma separated group on a new line in synonym settings and done.</li>
<li>Live search (aka autosuggest): Search as you type regardless of misspelling.</li>
</ul>
