What I mean is optical character recognition (OCR) on the silk screen 
layers. A common scenario is this: A layout is contracted out because 
the layout pros are usually less expensive than design engineers and 
also know the common industry practices much better. Often a schematic 
is not back-annotated and for a large board you then have trouble 
finding certain parts. "Now where did he/she place U43, and where is C97?"

Therefore, some Windows-based Gerber viewers have a function where you 
can key in "Find: C97". Then the Gerber view software performs an OCR on 
both silk screen layers, finds C97 and zooms into the location where C97 
is or places a blinking cursor there. I don't know how they exactly 
work, possibly they do the OCR in the background right after loading the 
silk01.pho and silk02.pho files so the program creates an internal 
coordinate list of where all the parts are. That would make the find 
response time much shorter because you don't have to run a fresh OCR 
every single time.
