There is no separate search component - search is a filter on the Products component (for the shop) and the Posts component (for the blog). Add data-v-search with the query and the listing shows only matches.
Usage
<div data-v-component-products data-v-search="shoes" data-v-limit="12">
<div data-v-product>
<h3 data-v-product-name></h3>
<span data-v-product-price_formatted></span>
</div>
</div>
Type the query in the builder's search setting or bind it to the ?search= page parameter. Single words match word beginnings automatically.
See the Products component and Posts component for all other settings.
