Create SearcherTaxoManager
--------------------------
Key: LUCENE-3786
URL: https://issues.apache.org/jira/browse/LUCENE-3786
Project: Lucene - Java
Issue Type: New Feature
Components: modules/facet
Reporter: Shai Erera
Assignee: Shai Erera
Priority: Minor
Fix For: 3.6, 4.0
If an application wants to use an IndexSearcher and TaxonomyReader in a SearcherManager-like
fashion, it cannot use a separate SearcherManager, and say a TaxonomyReaderManager, because
the IndexSearcher and TaxoReader instances need to be in sync. That is, the IS-TR pair must
match, or otherwise the category ordinals that are encoded in the search index might not match
the ones in the taxonomy index.
This can happen if someone reopens the IndexSearcher's IndexReader, but does not refresh the
TaxonomyReader, and the category ordinals that exist in the reopened IndexReader are not yet
visible to the TaxonomyReader instance.
I'd like to create a SearcherTaxoManager (which is a ReferenceManager) which manages an IndexSearcher
and TaxonomyReader pair. Then an application will call:
{code}
SearcherTaxoPair pair = manager.acquire();
try {
IndexSearcher searcher = pair.searcher;
TaxonomyReader taxoReader = pair.taxoReader;
// do something with them
} finally {
manager.release(pair);
pair = null;
}
{code}
