You might try http://www.getopt.org/luke/ to examine the /OMERO/FullText directory. Find an image that has passed through your bridge and look at its contents. It should have a field of the for A.B.C (or similar).
Unfortunately, I dont see a field of "image_name" for that image (which I tried to add) in the luke.
does this mean my code has some problem?
my code is exactly the same with the sample code
