I have website display list of jobs results and I have search criteria by location to display this jobs in the specific location

the client can select multiple location to search

I want put live google maps with markers showing where the jobs results are.

Map to be centered around the most accurate result.

but the problem if the client searched by more than one location as London and Guildford how I can display this google maps ,what is the parameter I should send to google map?

can anyone help me how I can display the results of the jobs be pinned on the map at the same time with multiple location ?
