Problem:
SharePoint search didn’t return search results on Large lists and libraries. On analyzing search crawl log, found the error logged: “The item may be too large or corrupt. You may also verify that you have the latest version of this IFilter.”.
Solution:
Make these registry changes in Index server and restart SharePoint search service. Once done, trigger the crawl again.
