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!

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 sc = sce.getServletContext();
String indexDir = sc.getInitParameter("indexDir");
SearcherManager sear
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(...);
}
finall
You can implement a ServletListener for your app and open the index there
(in the contextInitialized method). You can then create the SearcherManager
from the IndexReader/Searcher and store it in the ServletContext, where it
can be fetched out by your REST servlets.
This is a typical pattern that
Did you have a practical example of the use of SearchManager (initialize,
use to do research)?
Thanks in advance.

I use a singleton class but there are other ways in tomcat. Can't
remember what - maybe application scope.

Hi,
I'm trying to implement my code with SearchManager to make my app
thread-safe. I'm follow this post:
http://blog.mikemccandless.com/2011/09/lucenes-searchermanager-simplifies.html
There is a class that implements "SearchWarmer". I can't find this class in
the Lucene library, what class is th
Where I can initialize the SearchManager variable to after use it in the
REST servlet to do research in the index?

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 if
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 would
Take a look at org.apache.lucene.search.SearcherManager.
