I'm using Mac Catalina.
When you open the inline search, it sometimes gives you a dropdown menu so that you can select between "sentence," "paragraph," or "article." However, some books don't appear with the options, so when you search for some words, it shows you a whole paragraph rather than a simple sentence.
1) See the below picture. This is an example of not showing the dropdown menu, so as you see, when you search a word, you have to read a whole paragraph.

2) there is a dropdown menu on the right side. So, you can see the result more simple way.

I prefer the latter one because you don't have to read a whole paragraph and find the word quickly, but how can I add the drop-down menu on the first one if you don't see the option.
Are there any options that I can search a word or words through inline search so that you can see only sentences rather than a long paragraph?
