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.
