Support for date arithmetics in queries

[shyam81295]

It would be great if words like now, now-5h, now-1h can be used in dates, without being treated as simple string.

Parsing date : [now-1h TO now] would add more meaning to luqum. These human-readable queries are supported in Elasticsearch. See here Common options

P.S. When I checked, this feature was not implemented. Kindly reply, if it is already there.

Hello @shyam81295,

This is a good idea to support it. We should also consider supporting the original Lucene format (where "now" is "NOW").

Right now this won't be on our priority list, but you can contribute a PR, including tests.
