Which button is better when you want to load results from a filter?

I am redesigning an application and, one of our tasks is to redesign the UI and clarify/connect UI with the action intended. I noticed we are using different buttons for the same target action which is basically:

1 - Get results on a screen by submitting a button (after you choose which filters you want on).

Which option would be more user friendly and why and what are the advantages and main differences in-between these buttons?

Nowadays, on the web age, people got used to the same function applied to software and web applications. Would simply "Search" be the best option?

Search

update

go

reload

apply

Load Results
