Florin Haizea commented on HSEARCH-542:
---------------------------------------

After looking more into this issue and testing it more thoroughly I've found out the following:
1) The document contains each person name twice because I've annotated a class field and a class method using the same @Field name. So this was a bug in my code and had nothing to do with hibernate search.
2) The strange order of the results is given by a boost that I'm using for the field that is being searched: @Field(name = "full", boost = @Boost(2.0f)). If I remove the boost the results are ordered correctly. Apparently the boost is applied to all the names of a person, not only to the matching name as I thought. This caused the people with more names to have a higher score than people with one or two names which fully matched the search terms.

> Trying to index a simple relationship between a Person and a collection of Names. There are 2 issues:
> 1) The document containing the Person fields contains each name of that person TWICE. I think this may be affecting the score that the document receives. 
> 2) The search results are not ordered correctly. If I have one person with only one name: "Sly Stallone" and other people with multiple names, out of which one contains only "Sly" or only "Stallone", the people with multiple names have a higher score than the person with only one name that matches the search perfectly.
