Lucene index updation and performance
I am working on a job portal site and have been using Lucene for job search
functionality.
Users will be posting a number jobs on our site on a daily basis.We need to
make sure that new job posted is searchable on the site as soon as possible.
In this context, how do I update Lucene index when a new job is posted or
when an existing job is edited?
Can lucene index updating and search work in parallel?
Also,can I know any tips/best practices with respect to Lucene
indexing,optimizing,performance etc?
Appreciate ur help!
Thanks!

You can simply call IndexWriter.addDocument() for new jobs and
IndexWriter.updateDocument
http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/index/IndexWri
ter.html
Also, don't forget to optimize your index. Depending on your volume,
you might want to optimize during slow traffic.

You should look over the FAQ, lots of information there.
See: http://wiki.apache.org/lucene-java/LuceneFAQ
You can index and search in parallel, but a searcher doesn't
see additions to an indexer until the underlying IndexReader is
closed/reopened (see the FAQ section:
Does Lucene allow searching and indexing simultaneously?)
Best
