SUMMARY
In a pdf or epub.
When you have searched for something and you want to search an other part of the document, e.g. a later part, you scroll forward to the part you want to search and press search. The search moves back to the place you were before even if you have the option "From current page" enabled.
To force searching form current page I have tried:
Select a word on the current page so that it should deselect the word highlighted from the previous search, it does not work.
Pressed the red ball with 'x' and deleted the search and pressed ctrl+f to enable it again. After ctrl+f, I have the last search word as a suggestion, that is good, but pressing search takes me back to the previous location.
The only way to search from my current position, if my last search was the same word, is to delete the word suggested and type it in again. After that I can press 'Next' and get a search from the current  position.   


STEPS TO REPRODUCE
1. Open a pdf or epub with text and multiple occurrences of a word
2. Open search and open dorpdown menu 'options' and select 'From current page'.
3. Search for the word
4. Scroll past the page with the word, so that you also scroll past multiple instances of the word.
5. Search again

OBSERVED RESULT
Does not search from current page

EXPECTED RESULT
Should search from current page.
