I am using a Full Text Search Index issuing query medical terms in coming to nodes with concepts and looking for documentation on scores and score ranges, but not able to find!!
I am trying to setup a base threshold and hence trying to know the range of the scores which in this case varies.
Based on my observations the complete matches from 2 terms to 6 terms score ranges from 7.x to 12, and above 5 is probably a partial complete match.
But this is all empirical, having a range would allow a better handling of x-term matches with more normalized threshold.
Can anyone point to the documentation or advise on this. Thanks
