Document/Rem auto search while creating a document or Rem on the work flow in Android

Hi, when I am working on Android and taking the notes, sometimes it is required to insert the text as the reference to the rem, not a word. In this case I need to type: [[Orange]] in order to create of use the existing one. The problem, that when I type this, I am not sure if this rem is already exist and if so, you a risking of creating a copy of the ‘‘orange’’, but not refer to existing one if you miss the letter or upercase. In PC it is very convenient, that rem/document search works automatically when you type: [[, and you can select what definitely exists, and you will not create a similar new rem with similar name.
