Re: a function query of time, frequency and score.

2013-11-26 Thread Erick Erickson 
You can combine a whole series of mathematical
functions that take into account the values of fields
and use that for scoring. Functions can take other
functions as one of their operands, so you could
make something arbitrarily complex that takes into
account several of your fields.

If this still doesn't apply, please provide some examples
of what your docs look like and what you want to do with
them.

Best,
Erick

 Thanks, Erick.
 What I want to do is custom the sort by date, time, and number.
 I want to know is there some formula to tackle this.

 Thanks again!
