While testing with groupparam(i think it apply to field collapse as
well), I encountered a scenario where the number of suppliers in a
result is less than the number of items to display per page (user select).
Eg. Products per page to display is 80.
The search result has 182 matching productswhichbelong to 13 suppliers.
Grouping by supplier idand 1 product per supplier, only 13 products will
be return. Issuing anotherquery to getmore products to fill up the page
will not help as there is no more suppliers.
Initial query parameters,
start=0&rows=80&q=grout&fq=P_SupplierSource:(1)&group=true&group.field=P_SupplierId&group.format=simple
issue another query to get more products to fill up. this will not
return anyresult.
start=80&rows=80&q=grout&fq=P_SupplierSource:(1)&group=true&group.field=P_SupplierId&group.format=simple
Any suggestions/advice on how to address this scenario?

You can use expand and it will provide several documents per group
(but in a different data structure in the response).
Then it is up to you how to sequence or interleave the results in your
UI. You do need to deal with edge-cases like what happens if you say 3
products per group, but then one group has only one and you don't have
enough items in a list, etc.

Hi Walter
You used field collapsing for your case as well?
For my case the search result page is listing of products. There is a option
to select the number of products to display per page.
Let's say 40 products per page is selected. A search result has 100 matching
products but these products belong to only 20 suppliers. The page will only
display 20 products (1 product per supplier).
We still need to fill up the remaining 20 empty products.
How can I handle this scenario?

We had a similar feature in the Ultraseek search engine. One of our
customers
was a magazine publisher, and they wanted the best hit from each magazine
on the first page.
I expect that field collapsing would work for this.

Hope I understand what you meant by positive business requirements.
With a few supplier's products dominating the first page of a search
result, the sales will not be able to convince prospectiveor existing
clients to sign up.
They would like the results tofeature other supplier's products as well.
To the extreme case, they were thinking of displaying the results tobe in
such order
Supplier A product
Supplier B product
Supplier C product
Supplier A product
Supplier B product
Supplier C product
...
Theyare alright with implementing this logic tothe first page only
andsubsequent pages will be as per current logic if it is not possible to
implement it to the entire search result.
Will take a lookat Collapse and Expandto seeif it can help.

You have described your _negative_ business requirements, but not the
_positive_ ones. So, it is hard to see what they want to happen. It is
easy enough to promote or demote a particular filter matches. But you
want to partially limit them. On a first page? What about on the
second?
I suspect you would have to have a slightly different interface to do
this effectively. And, most likely, using Collapse and Expand:

Hi
We have a business requirement to breakupa supplier's products from
dominating search resultso as to allow othersuppliers' products in the
search result to have exposure.
Business users are open to implementing this for the first page of the
search resultif it is not possible to apply tothe entire search result.
From the sample keywords users have provided, I also discovered
thatmost of
the time a supplier's products that are listed consecutively in the
result
all have the same score.
Any advice/suggestions on how I cando it?
Please let me know if more information is require. Thank you.
Derek
