Grepping Multiple Strings on the Same Line 'Or'
I've got this command that I've been using to find strings on the same line, say I'm doing a search for name:

find . -name "*" | xargs grep -i "Doe" | grep -i "John" > output.txt

This gives me every line in a file that has John and Doe in it. I'm looking to add a OR operator for the second grep statement, so that I can grep for "John" OR "Jonathon" for example. In this example, I know that I could just enter "Jo*" but I don't want any other terms like Jose or Jonas.

I tried

find . -name "*" | xargs grep -i 'Doe\|John' > output.txt

but that didn't seem to work.

Thanks in advance.

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.
