what relevance means

Hello,

I discovered what relevance is about.
When I search for two words and both appear on a page, that page will have a relevance equal to 2002.
So, I believe that relevance is a multiple of 1001, showing how many search words were found.

what relevance means (2)

Hello again,

I did some more searches and i understood (i quess) the formula used for computing the relevance.

For example, if I search for two words (let's say: dotnetnuke project) in a text - which contains "dotnetnuke" twice and "project" once, the relevance will be:
2003 = 1002 + 1001 = (1000 + 1) + (1000 + 2)

So, a formula would be:
relevance = (1000 + no_occurences_word_1)
+ (1000 + no_occurences_word_1) + ....................

I think my intuition is correct, because this formula makes sence (for no_occurences < 1000).

To be honest, I am the one to be thankful :)
I am very pleased with your tutorials. I have watch only a few, but I found out - only here - some things which I was very interested in.

Good luck!

Sorry, I did a mistake in the formula.
The correct one is:

relevance = (1000 + no_occurences_word_1)
+ (1000 + no_occurences_word_2) + .................... +
+ (1000 + no_occurences_word_n)
