Hi,

you can use a script to find out term frequencies and more of a
particular word in a field. This feature is available since 0.90.10.
Check it out here:

You can use this either inside a function_score [1] query if you want
to use the tf to influence the score, or you can define a script field
[2] if you only want to have the information returned.

If you want to write a native script, some examples how to use that
from java are in this repository:

Hope that helps,
Britta
