Subject Warming Indexes
Date Wed, 14 Dec 2016 20:14:39 GMT

We are in the process of moving from lucene 2.9 to 6.3. We are going to use SearcherManager
and SearcherFactory classes for the first time and are wondering on how to warm our indexes
the first time. Below are the snippets of code, where we create our IndexWriter and SearcherManager.
And then we use searcherManager.acquire() to get IndexSearcher. Can somebody please guide
us on how to implement search warming? Would we need to warm each IndexSearcher that we get
from .acquire()?

   IndexWriter indexWriter = new IndexWriter(new NIOFSDirectory(new File(_indexLocation).toPath()),
    SearcherManager searcherManager = new SearcherManager(indexWriter, new SearcherFactory());
