Simple app to write notes on an Android cellphone

I have a MOTOROLA moto g android cellphone.  The carrier for my phone is T-Mobil .  I want to write notes using some sort of note app. I don't need lots of features just some basic note app where I can write notes and search for text.  I have searched Experts Exchange before asking this question but I cannot find any useful posts. 

Question:  What app would you install on an Android phone to write some simple text notes?  Must be able to search the notes for text.  

Thank you for your help.
