Hi,

Our application is based on MongoDB. We store the "names", "versions" and various attributes of IT assets in MongoDB. We have a new search requirement in which we need to retrieve the latest version of assets based on keywords. The catch here is that my versions numbers are of the format
x.y.z (i.e. major.minor.maintenance)

Basically, I should have the result set sorted first by major version (desc), then minor version (desc) and then maintenance version (desc).
e.g. For the version numbers given below:
1.0.10
1.1.0
11.0.0
2.0.1
The sorted version should be:
1.0.10
1.2.10
2.0.1
11.0.0
Is it possible for me to sort this correctly at Mongo layer itself? Unfortunately the version number is just stored as a single string value, and not a structured object in the x.y.z format.

Thanks in advance!
Zeba
