Issues Merging Two IF(AND) Formulas Together

Trying to a formula I have in two separate columns to function correctly under one column.

Been trying for about an hour but haven't managed to figure it out.

Formulas below:

Column1:

=IF(OR(ISNUMBER(SEARCH("Spare",K4)),ISNUMBER(SEARCH("Salvage",K4))),"Review","")

Column2:

=IF(AND(ISNUMBER(SEARCH("replace",K4)),I4<=0),"Review","")

Any help or guidance would be greatly appreciated. 

THanks!
