Subject Re: Indexing and searching a DateTime range
Date Mon, 09 Feb 2015 23:21:16 GMT
Thank you for taking your time to respond Karthik,

Can you show me an example how to convert DateTime to milliseconds? I mean
how can I pipe my converter logic into the indexing process?

I suspect I need to write my own Analyzer/Tokenizer to achieve this. Is
this correct?
