Hi. 

We want this year to convert all our paper receipts at home to scanned images, stored somewhere safely, but i want to be able to search for them without naming each file. 

We will likely store in PDF scanned from our Epson All in One.

There used to be a google desktop search which would search inside of PDF's, but that is long since gone. 

Anyone got something to replace it that will index network locations (No I don't want to use the HORRIBLE inbuilt MS Search).

We run Windows Desktop on multiple computers.
