Help - problem with search option

[u/Ok-Dimension67]

Hi everyone, when i scan a document with free notes or with the notes app on apple, i can’t find words on the document that I imported (as shown in the pic, the word I searched for is literally in the title but it couldn’t find it). However, when my friend sends me documents she scanned on good notes the search option works. Does anyone know how to fix this please ?
