Identify a part of a string in one column and return the entry in the neighboring column?

I have a spreadsheet of several thousand named items (in column B) with values associated with them in column A). The "name" field is a string of several alternative names for the item.

I have a list of ~50 items that I am trying to find the values for. Each uses one of the alternate names.

What I want is a function that will return the associated value in column A when one of my shortlist names is found.

For example, my big spreadsheet looks like:

A B
1 dallas, DFW. 12345
2 Atlanta, ATL, 23456
3 Boston, BOS, 34567
4 Chicago, CHI, 45678
5 Los Angles, LA, LAX, 56789

And my list looks like

Atlanta
CHI

I want the output to look something like:

Atlanta 2
CHI 4

Is the feasible? IT seems like there should be a way to do it....

Thanks in advance
