Facets and collections

[James Crowley]

If I have the following:

Event { type:"X", tags: ["tag1","tag2"] }

and an index like this:

from event in doc.events
from tag in event.Tags
select {
event.type
tag
}

using faceted search, I'm getting a count of 2 for type: "x" facet ?
Is this expected? I'm using .As<Event>() on the query, which gives me
distinct events in ToList(), but not for ToFacets(). How do I get it
to count only distinct documents?

Thanks!

James

Yeah that's expected, faceted search just takes all the terms in the index and gives you the count of how many times each term occurs

Facet search doesn't really make sense alongside As, it works in a different way from other queries.

If you want count of distinct events, you can change your index to this, (it should work)

    from event in doc.events
    select {
       event.type
       event.Tags.SelectMany(t => t)
    }

Thanks!

Almost, you need:

from event in doc.events 
    select { 
       event.type 

       tag = event.Tags

Thanks - I just skipped right past that option assuming it wouldn't
work! Perhaps stick in a collection to the example on
http://ravendb.net/docs/client-api/faceted-search ?

Matt,

Can you add that doc?
