Michael Busch updated LUCENE-730:
---------------------------------
Attachment: lucene-730.patch
New patch that deprecates the useScorer14 methods and adds new
methods:
/**
* Indicates whether hit docs may be collected out of docid
* order. In other words, with this setting,
* [EMAIL PROTECTED] HitCollector#collect(int,float)} might be
* invoked first for docid N and only later for docid N-1.
* Being static, this setting is system wide.
* If docs out of order are allowed scoring might be faster
* for certain queries (disjunction queries with less than
* 32 prohibited terms). This setting has no effect for
* other queries.
*/
public static void setAllowDocsOutOfOrder(boolean allow);
/**
* Whether hit docs may be collected out of docid order.
* @see #setAllowDocsOutOfOrder(boolean)
*/
public static boolean getAllowDocsOutOfOrder();
I think this is easier to understand for the users because it
tells them what they need to know (docs in or out of order)
and hides technical details (BooleanScorer vs. BooleanScorer2).
All tests pass.
