Error description

• Sometimes, URLs that query a product that exists in both the
  Catentry and Inventory index, intermittenly result in 0 products
   returned when you know that the URL should normally return 1
  product.
  
  This issue can manifest if the following conditions occur:
  - First, the SearchServiceWarmStarter fails to start due to
  missing coreNames in wc-search.xml or missing wc-search.xml file
   (within Search EAR).
  - Then, simultaneously hitting the server with multiple requests
   (for example 40 requests) might result in corrupted cache.
  
  When the SearchServiceWarmStarter does not start, combined with
  the server getting multiple requests, the
  SolrMultiMapDeltaSupportCache does not initialize successfully
  during at least one of the simultaneous requests. Therefore,
  subsequent requests do not update the
  SolrMultiMapDeltaSupportCache with the correct content. Since
  the cache is corrupted, there is no docId match from both
  Catentry and Inventory index, and hence no product is returned.
