If you mean that selecting a filter cancel the sort currently selected, then it is the way WPSOLR is working.

Eventually, you can select your sort algorithm field as the default one in screen “2.5 sort”

I’m not sure I understand the problem.

When I start a search, I can see that the default sort is “Relevancy”, not your own sort. It seems your sort is not the default one in screen “2.5 Sort”

Your configuration looks correct indeed.

I’ll have to test in my own environments.

I checked in depth the WooCommerce code, but could not find a way to force the WooCommerce sortby drop down list with a default value. I could not even make work the standard WooCommerce default sortby value (defined in the customizer).

The default sortby is applied by WPSOLR. But it is not displayed as selected in the WooCommerce dropdown list.

In woocommerce_catalog_ordering() of file wc-template-functions.php:
$default_orderby = wc_get_loop_prop( ‘is_search’ ) ? ‘relevance’ : apply_filters( ‘woocommerce_default_catalog_orderby’, get_option( ‘woocommerce_default_catalog_orderby’, ” ) );
$orderby = isset( $_GET[‘orderby’] ) ? wc_clean( wp_unslash( $_GET[‘orderby’] ) ) : $default_orderby; // WPCS: sanitization ok, input var ok, CSRF ok.

The 2 lines above show that the default orderby is always ‘relevance’ for search, unless ‘orderby’ url query parameter is set by a previous user selection.
