Combine Editions in this case?

[Jesus]

I am new to GR and I have had some difficulties while adding my first book, with help from Librarians it is now combined correctly with other editions. However I have noticed some facts:

1. Searching by title 'The Education of a Maiden' produce no matches, it is required to search by 'Education of a Maiden' to get matches.

2. Searching by title 'Education of a Maiden' there is a match with title 'Education of a Maiden, Part 2' that looks like the second part of this work. I wonder whether it should be combined or not.

3. In my own experience while reading 'The Education of a Maiden' and 'The Romance of Lust' I have found that 'The Education of a Maiden' seems to be Volumes 1 and 2 of 'The Romance of Lust' which has a total of 4 volumes. Again I wonder whether they should be combined or not.

We would not combine parts with other parts, or with larger parts.

I get your point but any ideas about how to register the relationship between these works? maybe creating a series?
