njy, the "score" will be computed using the sort by and the boost will be factored in. So yes - this is essentially what will happen.

Ok, thanks

Njy, I actually think that this would work, yes. Itamar can probably answer this better, but I am pretty sure that the boost value would only be a factor inside the same orderby value.

Using Boost gives more "importance" to some results, which actually means doing a (logical) additional "order by", is that correct? If it is like so, i was wondering if it could be possible - for example - to search news articles by a search term and get the results ordered by the date (to get the most recent firsts) and then, if the date is the same, by "boost value". It's just an example, i hope to have clarified the hypothetical scenario.

Njy, I don't understand the question

Jonty, It is important because it makes the values not dependent on strict ordering, but their basic importance as it relates to your actual query.

@Oren: is the value of the *Boost* available as a field in the result, or at least usable to specify a different ordering? Something like "order by *boost* desc" or something like that.

Same question as Jonty. Also what if You decide that Firstname is more important then AccountName?

How do you handle ordering when using boosting? Never use ordering? Will Skip/Take blow up for not being ordered?

Nevermind (https://github.com/ravendb/ravendb/blob/master/Raven.Client.Lightweight/Indexes/AbstractIndexCreationTask.cs)

Where is the source for the AbstractIndexCreationTask and AbstractMultiMapIndexCreationTask? From this angle, your method for isolating query logic looks similar to the specification pattern implementation that you were less than enthusiastic about (see here: http://ayende.com/blog/4784/architecting-in-the-pit-of-doom-the-evils-of-the-repository-abstraction-layer). But, I'm guessing it just seems that way because I don't know what the base classes are actually doing.

How is this better than order by?

That is very awesome. I'm looking forward to your feature set expansions!
