What's the best approach for using SOLR with web projects?

Question

ok, I\'m totally new to SOLR and Lucene, but have got Solr running out-of-the-box under Tomcat 6.x and have just gone over some of the basic Wiki entries.

I have a few q

Answer 1

1. No, you need a crawler for that, e.g. Nutch
2. Yes, you want two separate indexes ( = two schema.xml) since the datasets don't seem to be related. This doesn't mean two instances of Solr, you can manage the two indexes with Cores.

As for populating the Solr index, it depends on your particular project, for example, can it tolerate stale data or does it have to absolutely fresh.

Other options to index data include:

• Database triggers
• If you're using some sort of ORM use its interception capabilities. For example you can use NHibernate events to update the index on update, insert or delete. If you use NHibernate and SolrNet this is taken care of automatically
