Magento：覆盖Mage_CatalogSearch_Model_Resource_Helper_Mysql4

Question

I spent almost two days on searching the web about this topic, but i don't know why my class doesn't override Mage_CatalogSearch_Model_Resource_Helper_Mysql4 (core/Mage/CatalogSearch/Model/Resource/Helper/Mysql4.php).

My class is

class Company_Module_Model_Override_CatalogSearch_Resource_Helper_Mysql4 extends
    Mage_CatalogSearch_Model_Resource_Helper_Mysql4
{
}

the file is located in local/Company/Module/Model/Override/CatalogSearch/Resource/Helper/Mysql4.php

My config file is:

<global>
    <models>
        <catalogsearch_resource_helper>
            <rewrite>
                    <mysql4>Company_Module_Model_Override_CatalogSearch_Resource_Helper_Mysql4</mysql4>
                </rewrite>
            </catalogsearch_resource_helper>
    </models>
</global>

The module override other modules without problems, so I cannot figure out how to solve... Any idea? Thank you

Enzo，而不是做所有这些事情，只需从核心目录app \\ code \\ core \\ Mage \\ CatalogSearch \\ Model \\ Resource \\ Helper复制Mysql.php并将其粘贴到本地目录app \\ code \\ local \\ Mage \\ CatalogSearch \\ Model \\资源\\助手，并相应地修改您的代码

I am posting here the solution I came up with. The right override declaration in the config.xml file should be as following:

<global>
    <models>
        <catalogsearch_resource>
            <rewrite>
                  <helper_mysql4>Company_Module_Model_Override_CatalogSearch_Resource_Helper_Mysql4</helpr_mysql4>
            </rewrite>
        </catalogsearch_resource>
    </models>
</global>
