I'm wondering if there is a way to query the actual contents of the document using the REST API or using the CSOM and CAML from an ASP.NET application? I remember in a previous job that we used FAST search to accomplish this but it seems that FAST has been integrated into the search in 2013?
I've done some searching around but haven't found anything they tells me in black and white... It looks like simply using the querytext filter might do it?
Any advice would be very much appreciated!
Thank you
