When searching Arabic text it is hard for non-Arab speakers to spell the letter right. If possible like you search in Mac OS where it brings all related texts you are searching until you complete your text then you will have many options.

Also, when you want to search Arabic text is it possible that the font changes to Arabic automatically rather than being done manually.

Finally, after completing the text in the search box the "Enter" key on the keyboard doesn't work you have to click on the search button. If possible activate "Enter" key.
