Following up from another thread:
A thorough research tells us the following:
- ‘majjhimanikaya 1-50’ (with or without capital) brings no results.
- ‘MN 1-50’ or ‘mn 1-50’ brings no results.
- ‘MN’ as well as ‘mn’ brings results, namely a random selection of Majjhimanikaya Suttas.
- ‘MN1-50’ as well as ‘mn1-50’ brings results, namely a nicely ordered list of Majjhimanikaya Suttas from 1 to 50.
- ‘majjhimanikaya1-50’ (with or without capital) brings results, namely 50 times DN 34!
