Hi all,

I have a solr instance containing documents which have a 'startTime' field ranging from last month to a year from now. I'd like to add a boost query/function to boost the scores of documents whose startTime field is close to the current time.

So far I have seen a lot of examples which use rord to add boosts to documents whom are newer but I have never seen an example of something like this.

Can anyone tell me how to do it please?

Thanks
