All scores are null. Why?

I have a project that uses UnifiedSearch. The result from a search looks OK, but all hits are missing the Score. They all have null value as Score. Is this even possible? I thought all hits always have a score.

I wanted to do some boosting but when the score is null, it's a bit difficult to boost the score.

Hi Jocke

Are you performing any free-text search in your query? I.e. .For(query);
Boosting only has an effect if there is an existing score to boost.

Hi!

I found the answer myself just now! If I have OrderBy() in my statement the Scores are set to null. As soon as I remove the OrderBy all hits will have a score!

Hmm

Maybe you have to do "OrderByRelevance" which is the default.

You could perhaps add

public static ITypeSearch<TSource> OrderByScore<TSource>(this ITypeSearch<TSource> search)
{
    return new Search<TSource, IQuery>(search, context =>
    context.RequestBody.Sort.Add(new Sorting("_score")));
}
