Hi David,
Thanx for your reply. Now that configuration is correct.
please take a look at second requirement.
Here is the scenario.....
I am indexing products in solr and each product belongs to "categories"
and categories belong to CategoryGroup.
Now that product and Category and CategoryGroup are indexed in solr.
For example:
Here are the Categories and CategoryGroups
BookType
ScienceFiction
Children
Adventure
No of Pages
100 -500
500 - 1000
>1000 or more
*I need to get similar books for Book1*
Book1
BookType
ScienceFiction
Children
Adventure
No of Pages
100 -500
-----------
Book2
-- BookType
-- ScienceFiction
-- Numberof pages
-- 100 - 500
----------------
Book3
BookType
ScienceFiction
Children
No of Pages
100 - 500
------------------
Say i can provide the boost for Categorygroups BookType = .5 and No of
Pages = .5
Then morelikehandler should consider category and also the boost given to
the respective CategoryGroup like below....
Book2 score ..
1 X .5 + 1 X .5 = 1.0
Book3
2 X .5 + 1 X .5 = 1.5
So the Book3 will be more similar to Book1 compared to book2. What i want to
achieve here is while calculatting the score both Category and CategoryGroup
are considered.
Please let me know what needs to tweaked in MoreLikeThis handler. So that
this can be achievd.
Thanks
Nayan
