grep will return all lines that contain a searched-for string.
And I have seen some odd results when the lines are not delimited as usually expected with a line-feed at the end of each. So, that is a first thought - that your file is not correctly delimited. (see commands like dos2unix and unix2dos for more on this)
The next issues are capitalization and spacing. The grep command, without additional options, is an exact match. This relates to my comment on spacing as there might be two spaces between certain words, they words may be on separate lines, there could be tab characters between the words.

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.
