If you run an online shop or blog, where you would like to add filters to sort products or posts, you can use JetSmartFilters plugin. Let us introduce you new functionality, which is available in JetSmartFilters now and called Indexer.
What is Indexer? With this feature, you get the opportunity to save the filtering data in the database with its further retrievement. In other words, on the frontend will be displayed only the results relevant to the selected filter (the non-relevant results can be hidden or disabled).
We present an example based on filtering WooCommerce products using smart filters.
