Hi Mark,

Where can I find some info about the search methods the Webinator is
performinf when someaone searches? What is important to rank the results
(title, metatags, body etc) And how are the indexes built? I try to find
out how I can influence the page's content to give pages more or less
importance.

Gr,

The ranked search in Webinator works as follows:

A: An individual term's importance is inversely proportional to its overall
frequency within the database. (IE: Less frequent terms are more
important.)


B: Term match position within a document is taken in to consideration.
The closer to the beginning of a document the better.

C: Term match order with respect to other terms taken into consideration.
D: if two matches are of equal rank value then insertion order into
the database will determine which is output first.

Therefore:

A document which begins with the exact phrase in the exact order
that the user typed as a query will be ranked as the highest match.

A document containing only one of the terms in a multi-words query,
where the matched term is in half the documents in the database
will be very low ranking.

Hope this helps
