random results at specific slots

[srinir <sr...@nextag.com>]

Hi,

I would like to return results sorted by score (desc), but i would like to
insert random results into some predefined slots (lets say 10, 14 and 18).
The reason I want to do that is I boost click-through rate based features
significantly and i want to give a chance to documents which doesnt have
enough click through rate data. This would help the results stay fresh.  

I looked into solr code and it looks like i need a custom QueryComponent
where once the top results are ordered, i can insert some random results at
my predefined slots and then return. I am wondering whether there is any
other way I can achieve the same?

Thanks
Srini

Other option I could think of is to write a custom component which implements
handleResponses, where i can pick random documents from across shards and
insert it into the ResponseBuilder's resultIds ? I would place this
component at the end (or after QueryCOmponent). will that work ? is there a
better solution ?

Take a look at "query elevation". It may do exactly want you want, but at a 
minimum, it would show you how this kind of thing can be done.
