MN.Net Ranking Project

In the ML.Net Ranking sample project, the consumption of the model is not clear. For example : After the model is trained and saved, it has to be used with the new query to rank the web searched. The example provided is not clear. Suppose, we want to use the web query for "testing tool", how does this has to be passed to the model so that model will return a list of URL_Ids with proper score so that it can be ranked. More challenge is : what happern when the query "?????" has not been queried before or there is no groupId in the test data, how will be ranked. Calling Prediction might return null.

So a concrete examples will be helpful.

May be anothe sample with the Hotel selection using ML.Net will be helpful.

Have been working on this for quite some time. Having trouble figuring out how to consume the model.

Appreciate any help / samples /tips.
