Hi,
I have a strange problem with lucene in one of my projects.
My business application adds business objects which are stored in a
database into a lucene index. So each time a user creates a new business
object the data is added into the index.
This works all fine. The project is a JSF Web Application and I use a
simple pojo class to update the index.
I create the indexWriter in the following way:
Directory indexDir = createIndexDirectory(prop);
Analyzer analyzer = new StandardAnalyzer();
IndexWriterConfig indexWriterConfig = new IndexWriterConfig(
Version.LATEST, analyzer);
indexWriterConfig.setWriteLockTimeout(10000);
Full code can be reviewed at Github
(https://github.com/imixs/imixs-workflow/blob/master/imixs-workflow-engine/src/main/java/org/imixs/workflow/plugins/jee/extended/LucenePlugin.java)
Now we have the problem, that in some cases (we guess it happens when
users add objects in very short time frames 3-5 objects in one minute)
no index is added.
I also got no exception so it is hard to identify the case when it
happens. The result is that some objects are not listed in the index.
When I call my update-method for these objects once again everything is
fine.
Can anybody give me a hint what could be wrong with my approach. Maybe
for web applications with multi-user access I need to take more care how
to create the indexWriter?
Thanks for any help
Ralph
