User cannot see files in document library and sharepoint search not returning results from specific document library.I came across this search error where user is trying to search documents selecting the option “search in same site” instead of “all sites” from search box and sharepoint search not returning results. User can find documents from other library with in same site but cannot see files in specific document library.
When gathering files from a content source, the SharePoint 2013 Crawl Component can be very I/O intensive process – locally writing all of the files it gathers from content repositories to its to temporary file paths and having them read by the Content Processing Component during document parsing.
