Mysql order by is very slow from 1,000,000 rows, we have nearly 300,000 search results

Question

When we do Natural Search in Mysql from 1,000,000 rows, we have nearly 300,000 search results. This query lasts 7-8 seconds when we want to select the first 2,000 documents with the highest natural score.

This time is too long for us. How can we shorten the duration of the first 2,000 pick by sort by natural rating?

Thank you in advance for your help.
