[jira] Reopened: (LUCENE-2831) Revise Weight#scorer &
Filter#getDocIdSet API to pass Readers context
[ https://issues.apache.org/jira/browse/LUCENE-2831?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Muir reopened LUCENE-2831:
---------------------------------
There are some issues here with IndexSearcher, mostly found with LUCENE-2751 (once we started randomly using the executor service in tests).
# some recursion bugs in IndexSearcher(IndexReader r, boolean closeReader, ExecutorService executor)
# i noticed problems with IndexSearcher(ReaderContext topLevel, AtomicReaderContext... leaves), the varargs causes this ctor to become ambiguous with other ctors (such as ReaderContext, ExecutorService). I don't understand why this ctor needs to be public, i noticed Solr's QueryValueSource is the only thing using it, and I think instead that should be fixed.

> Spinoff from LUCENE-2694 - instead of passing a reader into Weight#scorer(IR, boolean, boolean) we should / could revise the API and pass in a struct that has parent reader, sub reader, ord of that sub. The ord mapping plus the context with its parent would make several issues way easier. See LUCENE-2694, LUCENE-2348 and LUCENE-2829 to name some.
