* Cleans a cache of search requests when attribute's search weight is changed.
*
* A product attribute in Magento contains a property named 'search_weight'.
* This property should be passed to a search adapter.
* And container which is responsible for this is the Search Request.
*
* However, search requests are dynamically generated and therefore cached in the Configuration cache.
*
* But, as they're cached, there is a problem when search weight is changed for an attribute
* as it will not change in the cache.
*
* This plugin solves this issue by resetting cache of search requests
* when an attribute's search weight is changed.
