Hello,
The 13000 products are too large to keep good performance in native WooCommerce search engine.
The best solution is to check other search plugins or upgrade to the Pro version.
Let me explain the difference between the Free and Pro versions of the search engine we use.
The Free plugin version uses a native WooCommerce search engine. It means that the search speed depends on many factors:
- How many plugins do you have?
- How many products do you have?
- How your WordPress is optimized?
- How your server is fast?
- How big is the search scope?
The Pro plugin version has a different search engine based on the fastest PHP search engine TNT Search. Also, we added a lot of tricks in the Pro version e.g. special SHORTINIT WordPress mode. It means, that every search query doesn’t need to load unnecessary files including all plugins, theme, and a big part of WordPress core files. So the search is always fast, no matter how many plugins you have or how your website is optimized (or not optimized).
The average search speed for 50 000+ products takes about 0.2 second per request (standard shared hosting). For users who have a fast server, it takes even less than 0.1 second. The Pro plugin is always ultra-fast.
The search speed is our obsession, so speed is a core feature in the Pro plugin version.
