For the singleton technique that I use, the per-search code looks like
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.SearcherManager;
SearcherManager sm = LuceneSearcherManagerCache.get(indexdir);
IndexSearcher s = sm.acquire();
try {
search(...);
}
Something like:
public class SearchListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
ServletContext sc = sce.getServletContext();
String indexDir = sc.getInitParameter(indexDir);
SearcherManager
Why use Solr instead of Lucene for this kind of application?

Something like:
public class SearchListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
ServletContext
Mostly because it already handles all of the I sexing and querying that I
expect you'll want to be doing and now with Solr Cloud you can ven scale
search beyond one machine.
If you're just looking to learn about this stuff, though, it is fun to roll
your own!

Take a look at org.apache.lucene.search.SearcherManager.
From the javadocs Utility class to safely share IndexSearcher
instances across multiple threads, while periodically reopening..

Hi
You want to use REST service for your search, then my advice would be to
use Solr. As it has buitl-in functionality of REST API.
If you want to use Lucene then below are my comments:
1. In do search function, you are creating reader object. If this call is
invoked for every query then it
I think that blog post was bleeding edge and the API changed a bit subsequently.
I use
Directory dir = whatever;
SearcherManager sm = new SearcherManager(dir, new SearcherFactory());
to get default behaviour. The javadocs for SearcherFactory explain
that you can write your own implementation
Where I can initialize the SearchManager variable to after use it in the
REST servlet to do research in the index?

Hi,
I'm trying to implement my code with SearchManager to make my app
thread-safe. I'm follow this post:

There is a class that implements SearchWarmer. I can't find this class in
the Lucene library, what class is
I use a singleton class but there are other ways in tomcat. Can't
remember what - maybe application scope.

Did you have a practical example of the use of SearchManager (initialize,
use to do research)?
Thanks in advance.

You can implement a ServletListener for your app and open the index there
(in the contextInitialized method). You can then create

Hi,
I'm developing a web application, that contains a REST service in the
Tomcat, that receives several requests per second.
The REST requests do research in a Lucene index, to do this i use the
IndexSearch.
My questions are:
- There are concurrency problems in multiple research?
- What the best
