Pipe output of wget through grep using php url

I am trying to pipe the output of a wget command through grep. The url is a php file with parameters. I can do it as 2 separate commands but would like to combine them so I do not have to write the file to the disk.

This code does not work (the result is always unsuccessful) -
wget --output-file=wgetlogfile2.txt --O - http:/www.domain.com/custinv5.php?parm1=ABC&parma2=DEF | grep -qi STRING'

This code does work -  
wget --output-file=wgetlogfile2.txt --output-document=testdoc.html http:/www.domain.com/custinv5.php?parm1=ABC&parma2=DEF 
sleep 2
grep -qi 'STRING' testdoc.html
if [ $? -eq 0 ]                        

If I remove the "sleep" from the code that it works, it fails

Any ideas would be appreciated.

Note special case hyphen after O means the document will be written to standard output:

wget -qO-  http:/www.domain.com/custinv5.php?parm1=ABC&parma2=DEF | grep -qi 'STRING'

I have that in option in my command."--O -".  I had a typo when I entered the question having put two dashes in front of the "O".  There is only one dash.

I have resolved my problem.   I had to enclose the URL in quotes.

Thanks for your comment.
