Trouble with notes app...

Hi, I have a little problem when I try to use a notes app. When I put on the search bar the exact thing that I want, the system show me the beginning of the part that I want but when I select the item and the note pad it open, I can’t see the exact area of the note that I want, so I need to found them in the whole note reading part by part. In the past when I do the same I can found the exact part of the note quickly, now I can’t. Can you help me fix that o this is unfixable because the IOS change that.? Thanks.!
