I'm working on sharepoint online and i used content search webpart to display documents. I used the ServerRedirectedPreviewUrl property to the picture url managed property to get the thumbnails but i m not getting thumbnails for the Excel documents. Its working file for Word documents and power point documents. Pls refer the screen shot. The SP online is the excel document. Please help me to solve this issue. Thanks in advance!
