I'm using ES 1.7 to build a classfied ads search engine. This works pretty good. I'm crawling the web and indexing in my ES instances.
Now i have like to force Elasticsearch to display the results of at least 6 different websites on the first page even if they are less relevant.
In my current case, only the Ads from a specific website are been displayed on the first page because his content is always most relevant that the others.
How can i trick it, at least for the first page of results ?
