Excel: adding value if the other cell contains certain value

Question

here is the problem which is pretty self explaining.

I need excel to run through each row in A column and if it's 'volvo' (in this case) i need it to add the value next to it.
The sum of values should be in the cell below (A5).
The poor solution which I came up with and does not work is
=SUM(IF(ISNUMBER(SEARCH("volvo";A1:A3));B1:B3;0))
Thank you for every reply!

Answer 1

使用SUMIFS（）

=SUMIFS(B:B,A:A,"volvo")
