I am building a iOS app with Firebase, and using ElasticSearch as a search engine to get more advanced queries.
I am trying to achieve a system where I can get a random record from the index, based on a query. I have already got this working using the "random_score" function with a seed.
So all documents should right now have equal chance of being selected. Is it possible to add a boost or something(sorry, I am new to ES)?
Let's say the the document has the field "boost_enabled" and it set to true, the document will be 3 times more likely to be selected, so "increasing" the chance of being selected as a random?
So in theory it should look like this:
Documents that matches the query:
They all have an equal chance of being selected (33%)
What I wish to achieve is if "document1" has the field "boost_enabled" = true
It should look like this:
So now "document1" is 3 times more likely to be selected as the random record.
Would really appreciate some help.
