google search

We use different search solutions on a variety of our drupal sites. Some use Solr, some use core, some use Lucene, and some use Google search.

Half of me thinks that search should be "in house" and half of me thinks using outside sources like google for searching is the way to go. I know there is really "no one size fits all", and no "the only right way" but I want to pick one side and go with it.

One advantage of using search in house is you have complete control over how the search results look. But it also uses more resources.
