Question

I understand how Lucene.net can work for text indexing. Will I be able to efficiently search for documents based on a given date range? Or will Lucene.net just use text matching to match the dates?

Answer 1

Lucene.Net will just use text matching, so you’d need to format the dates correctly before adding to the index:

    public static string Serialize(DateTime dateTime)     {         return dateTime.ToString('yyyyMMddHHmmss', CultureInfo.InvariantCulture);     }      public static DateTime Deserialize(string str)     {         return DateTime.ParseExact(str, 'yyyyMMddHHmmss', CultureInfo.InvariantCulture);     } 

You can then, for example, perform a range based query to filter by date (e.g. 2006* to 2007* to include all dates in 2006 and 2007).
