Gagan Deep Juneja commented on BLUR-174:
----------------------------------------
If I understand this issue correctly then we need to order the resultant
documents ( with same row id ) in the order of families passed as per selector.
So where should we intervene in the existing process, should we alter scoring
mechanism or write comparator for that, because right now indexSearcher returns
documents based on the default scoring mechanism. And I don't think the order
in which we create query would impact this.
Can there be multiple families in same document.
Please share your point of view on this.

Gagan

> Issue Type: Bug
> Components: Blur
> Affects Versions: 0.2.0
> Reporter: Aaron McCurry
> Priority: Minor
> Fix For: 0.2.0

>
> We need to respect the order of the families in the selector. For instance
> if a table contains 3 families, "cf1","cf2", and "cf3". And a fetch (during
> a query or a fetch call) is performed and the order of the families are
> "cf2", "cf1" then all the records from the Row that contain "cf2" should come
> before "cf1".
> Changes needed:
> The families in the Selector object in thrift need to be changed from a set
> to a list.
> The fetchDocuments method in the BlurUtil class in blur-core needs to be
> modified to respect the family order.
