Hi there,

You can use WC_Product_Data_Store_CPT::search_products to do a product search similar to the s param on WP_Query.

wc_get_products does not support partial title search, but it does have support for custom params if you want to add this functionality to whatever you are doing.

Hope this clears things up. Thanks.

For anyone else (and likely myself while googling this problem again) who needs a more straightforward resolution to this problem feel free to use the following code snippets.

/**
 * Add support for 'search_term' query var (Add to functions file)
 */
function support_search_term_query_var( $query, $query_vars ) {
    if( empty( $query_vars['search_term'] ) ) {
        return $query;
    }

    $query['s'] = $query_vars['search_term'];
    return $query;
 }
 add_filter( 'woocommerce_product_data_store_cpt_get_products_query', 'support_search_term_query_var', 10, 2 );



 /**
  * Usage
  */
 $my_search_term = $_POST['search'];
 $products = wc_get_products([
    'limit'          => 10,   
    'post_type'      => 'product',
    'search_term'    => $my_search_term,
    'visibility'     => 'catalog',
]);

Sorry! In retrospect that wasn't a super helpful response because the line I linked to now points to a different thing. :) Thanks for adding the snippet.

For reference, this is what my recommendation looks like as a snippet:

$data_store = WC_Data_Store::load( 'product' );
$search_results = $data_store->search_products( 'my-search-term' );

function support_search_term_query_var( $query, $query_vars ) {

    return $query;
 }
 add_filter( 'woocommerce_product_data_store_cpt_get_products_query', 'support_search_term_query_var', 10, 2 );



 /**

 $my_search_term = $_POST['search'];
 $products = wc_get_products([
    'limit'          => 10,   
    'post_type'      => 'product',
    'search_term'    => $my_search_term,
    'visibility'     => 'catalog',
]);

We can't use order id as the search term. It will return zero result.

This code is a part of my custom search endpoint, its results are similar to woocommerce REST API endpoint
/products?search=keyword

$args = array(
           'post_type' => 'product',
           'posts_per_page' => 10,
           'paged' => $page,
           's' => $request['s'],
           'paginate' => true,
           'meta_query' => array(
               array(
                   'key' => '_sku',
                   'value' => $request['s'],
                   'compare' => 'LIKE',
               ),
               array(
                   'key' => '_title',
                   'value' => $request['s'],
                   'compare' => 'LIKE',
               ),
           ),
       );

       $query = wc_get_products($args);
       //get products 
      $products=  $query->products
