Find Multiple Strings from a list of *.gz files withour decompressing...

Hello Team,

There is this situation where there are around 20 *.gz files and i want to search multiple words from all those files.

Example as below :




now i want to search words "hi" and "hello" from all these 3 files without decompressing them in a single command.

I tried :

zgrep hi *.gz and zgrep hello *.gz .

but i dont know how could i apply search for "hi" and "hello" in only one command....

I also tried zgrep "hi | hello" *.gz but it didn't work.

Please suggest how can i find multiple words without decompressing *.gz files....
