Hi!
Can anyone tell me how the scoring algorithm SCORE is calculated? I want to calculate it manually. I therefore need to know how Oracle calculates this algorithm, and how it works with different query statements.
First: How does Oracle counts words?
If a contains query against an indexed (context index type) set of documents is: "whale", will also "whales" count as one word?
Does anyone know how Oracle calculates SCORE in a query that contains boolean operators like AND/OR/NOT? Or in a query that contains more than one word?
It is very difficult to find information on this algorithm, I hope some of you can help me!
Helene.
