Combining an IF and Find function

Hi all,

Trying to write an if formula to do the following:
If the text in cell A1 contains the word "Port", generate the word "INTERNATIONAL" in B1.
If A1 contains the word "MINE", generate the word "DOMESTIC" in B1.

I played around with a combination of an if and find formula but struggling a bit. Attached my workings

Maybe something like this:

=IF(ISNUMBER(SEARCH("Port",A1)),"INTERNATIONAL",IF(ISNUMBER(SEARCH("Mine",A1)),"DOMESTIC","Other"))

Perhaps =IF(ISNUMBER(SEARCH("port",A1)),"international",IF(ISNUMBER(SEARCH("min",A1)),"domestic",""))

nice one thanks peeps!
