I'm in the process of migrating a medium-sized on-line magazine to Drupal.
I do not know much of Drupal's internal search engine capabilities, but I'm aware of the Apache Solr Search Integration module, which integrates the java-based search engine from Apache. Unfortunately, Solr is something new to me too.
So my questions are:
- When should I use Apache Solr instead of the Drupal core search? In what type of websites core functionality is not enough? Should I care about the performance gains of using Solr if my visitors only do hundreds of searches per day?
- Will learning how to use and integrate Apache Solr cost me lots of weeks/months?
