Do not show similar products in recommendations

[ambikaTewari_ATCI]

Hi Team,

I have such data in the feed :

##entity.id	entity.name	entity.offerType	entity.inventory
11-SPO	aa	11	1
23-AS	bb	22	1
34-PO	cc	11	0
45-UI	dd	13	4
56-OK	ee	11	1

offerType can have the similar value .

Recommendation could return top 3 entities but 11-SPO and 34-SPO would be similar item. how do I stop 34-PO not to show in recommendatons?

Hi, 

You might want to create a criteria sequence where each criteria has a filtering condition to look into the pool of similar items, then apply "limit the number of items" to 1 for each criteria. In that way every criteria will return only a single product. 

Let us know if that works.

Hi @kchaitanya 
We have such data in feeds :

We do not want "1328001-CHIES" to show up in recommendationx because "1328001-CHIDG" entity has the same entity.offerId. 
The collection/pool could have such  entity.ids who would have similar entity.offerId (such entities have entity.propertyType as MPO). I do not want entity.id  ("1328001-CHIES") to be shown in next slot by criteria if the another   entity.id ("1328001-CHIDG") with the similar entity.offerid (1328001) is already present in the previous recommended slots  .

In the filtering option, I do not see such option to accept first entity.id of such group (MPO) and then pick 1328001-CHILY and show it.

Hi @ambikaTewari_ATCI , 

There definitely isn't the dynamic option you are looking for in the criteria filters (at least for now). If the number of offers is limited and manageable manually then you could try using static filters in the criteria sequence (of course you will have to come up with a preference sequence of the offerIds). 

One other idea is to handle this logic in the design. In your design HTML/JS code your developers can add the logic of checking with the previous recommendations offer id ($entityX.offerId) and only render the next product if the value is different, otherwise skip to the next product returned from the criteria. Check this section for inspiration of the code:

Hi @kchaitanya That helps! thank you.

I'll try to add the logic in design to control the duplicate values.
