Conditional Formatting: column A based on text values in columnB

Hi,

I am trying to figure out a way to use conditional formatting to highlight the cells in column A based on the specific text in column B.

I have tried =ISNUMBER(SEARCH("text",B1:B4))=TRUE
but this highlights all of column A, as seen below.

What I want to do is have it formatted like this:
where the cells in column A are only highlighted when the word "text" appears in column B.

So far, I have been unsuccessful.
If this needs to be a macro, that is fine, but the vba code would be appreciated.

Thank you!
