Magento 2 - Plugin issue in catalogsearch

Question

I've created a plugin to override getProductPrice() method of Magento\Catalog\Block\Product\ListProduct class. This is my app/code/vendorName/moduleName/etc/di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Block\Product\ListProduct">
        <plugin name="vendorName_moduleName_Plugin" type="vendorName\moduleName\Plugin\MyPlugin" />
    </type>
</config>

and this plugin class (app/code/vendorName/moduleName/Plugin/MyPlugin.php):

<?php

namespace vendorName\moduleName\Plugin;

class MyPlugin
{
    public function afterGetProductPrice(\Magento\Catalog\Block\Product\ListProduct $product, $result)
    {
        return $result.'<input type="hidden" class="my-class" />';
    }
}

It works fine when a category page is called but it doesn't override methods when I try to search a product.

Why?

Thanks to @fschmengler and reading Magento 2: virtual types plugins I solved using this app/code/vendorName/moduleName/etc/di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Block\Product\ListProduct">
        <plugin name="vendorName_moduleName_Plugin" type="vendorName\moduleName\Plugin\MyPlugin" />
    </type>
    <virtualType name="Magento\CatalogSearch\Block\SearchResult\ListProduct">
        <plugin name="vendorName_moduleName_VirtualPlugin"
                type="vendorName\moduleName\Plugin\MyPlugin" />
    </virtualType>
</config>

You need to create another plugin for it

app/code/vendorName/moduleName/etc/di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\CatalogSearch\Block\SearchResult\ListProduct">
        <plugin name="vendorName_moduleName_Plugin" type="vendorName\moduleName\Plugin\MyPlugin" />
    </type>
</config>

Your plugin file at app/code/vendorName/moduleName/Plugin/MyPlugin.php

<?php

namespace vendorName\moduleName\Plugin;

class MyPlugin
{
    public function afterGetProductPrice(\Magento\CatalogSearch\Block\SearchResult\ListProduct $product, $result)
    {
        return $result.'<input type="hidden" class="my-class" />';
    }
}
