Lucene: Indexing DateTime from Sitecore and querying date ranges

The title should be self explanatory. I need to index some sitecore items that represent some entities that are valid to the public between certain dates. The sitecore fields are date time fields looking like this.


I needed a solution for indexing these values in a way that i can do range queries on them. I used the UnixTimeStamp for converting the DateTime field in a UnixTimeStamp field.

Decoding UnixTimeStamp to DateTime :

The fields would then be indexed as numbers and i could filter the results using a TermRangeQuery on the index like this:

I think this solution is quite elegant and easy to use.
