Hi.

You've taken the filename as input to grep, so you are grepping on the filename, not on the file contents, as you imagined.

try using
Code:
find ... | xargs grep u28507

or better
Code:
find ... | xargs -I{} grep u28507 {}

Code:
$ cat file1
start
  u28507
end

$ find . -name file1 | grep u28507                   

$ find . -name file1 | xargs grep u28507 
  u28507

$ find . -name file1 | grep file1 
./file1

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
