is there a way to lower the query cost of this query

SELECT

s$.$staff$\_$id$,$

CONCAT$($s$.$first$\_$name, $\text{'}\text{'},$ s$.$last$\_$name$)$ AS staff$\_$name,

SUM$($p$.$amount$)$ AS total$\_$sales

FROM

staff s

LEFT OUTER JOIN

rental r ON s$.$staff$\_$id $=$ r$.$staff$\_$id

LEFT OUTER JOIN

payment p ON r$.$rental$\_$id $=$ p$.$rental$\_$id

LEFT OUTER JOIN

inventory i ON r$.$inventory$\_$id $=$ i$.$inventory$\_$id

LEFT OUTER JOIN

film f ON i$.$film$\_$id $=$ f$.$film$\_$id

WHERE

p$.$payment$\_$date IS NOT NULL

AND f$.$description LIKE $\text{'}\%$Boring$\%\text{'}$

AND f$.$description LIKE $\text{'}\%$Lumberjack$\%\text{'}$

AND f$.$description LIKE $\text{'}\%$New Orleans$\%\text{'}$

GROUP BY

s$.$staff$\_$id$,$

staff$\_$name

ORDER BY

total$\_$sales DESC;
