Hi, We want to be able to suggest entities to customers that are similair to their entity. For example, i create a \*wishlist \*and add 10 products to that list. Another customer also created a wishlist with 20 products on it and there are \*6 \*products that are the \*same \*on both lists. We want to be able to suggest the list from the other customer to myself. The 'more like this' API seems like it can be used but there is very little control over what you can configure. The more like this query is more flexible but i don't want to provide text, i simply want to say: "search lists that are like mine based on the array of productId's from my list where there should be at least 5 (exact) matches". Is this possible with elasticsearch? If so, which way to go? Thanks, Maarten -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi, Not yet, what i did was: - flatten the data to 1 property (productIds) so it is an array of productId's - use the API and it worked quite nicely, but i have no control over other things like, only compare to lists with more than 5 productId's. What i'm not certain of if i could use nested objects instead of productId's. I could of course do both! Firstly I'll try to rewrite the mtl API as an mtl query so i get the same result, from that point on i'll use your link to configure a more precise result.

Hi Jörg, How do i proved the user's wishlist when using the mlt query? i've tried: GET [http://localhost:9200/wishlists/list/](http://localhost:9200/wishlists/list/)_[id user's wishlist_]/\_search/ { "more\_like\_this" : { "fields" : ["product\_id"], "min\_term\_freq" : 1, "max\_query\_terms" : 12 } } but it does not work.
