[Plugin: SEO by Yoast] Stop words issue

Hi all
I tried to search the forums but it looks like this topic was discussed three years ago but did not find any solution.

I installed SEO by Yoast plugin. I noted that i have an issue with stop words: for example if I have a post titled “Best food in Italy” and I set the focus keywords as “Best food Italy”, the plugin rates the page red as the title differ from the keywords (extra “in”).
Same happens when keywords are unrelated to each other, for example when I set “football summer seaside” as keywords: if there is not *exactly* that sequence of words in the text, the plugin rates it red.

Any workaround?
Many thanks!!
