Hello,

I'm wondering if the following query should be possible -  
[http://localhost:9200/test\_index/article/1119/\_mlt?search\_types=image&fields=title&size=1](http://localhost:9200/test_index/article/1119/_mlt?search_types=image&fields=title&size=1)

What I'm looking for is the ability to get more documents of type  
image based on the article.title field for the specific id. The  
documentation seems a little vague on the point of search\_types.

The size doesn't seem to work either for a standard \_mlt query.

I'm using version 0.16.2

Cheers,  
-Ed
