GroupBySite defines whether to group
search results by site.
If GroupBySite is set to yes,
then mnoGoSearch presents only a single document (with the highest
score) from every site and adds
a "More results from this site (nnn total)" link,
were nnn is the number of documents found on the given site.
If you click this link, mnoGoSearch will present all the nnn
documents found on this site.
If GroupBySite is set to rank,
then mnoGoSearch presents all found documents, without site grouping
(the same document set which would be returned by
but sorted in a special way. Score of every document is additionally
divided by the rank of this document in its site. So score for the best
document on a site is not changed, score of the second best document
from the same site is divided by 2, score of the
third best document from the same site is divided by
3, and so on. This GroupBySite
mode effectively displays on the highest positions the documents
which would be returned by GroupBySite
yes (i.e. the best documents for every site found),
and then appends the other documents from different sites intermixed.
This mode prevents displaying of multiple documents
from the same site successively and thus gives a chance for all
found sites to be presented on the top result pages.
Grouping results by site can also be activated using the
parameter in the search query string. However, if you specify GroupBySite
in search.htm, the query string parameter is ignored,
i.e. the command specified in search.htm has higher precedence other
the search query parameter.
The default value is no.
