third party search server and their modules for drupal 7

Question

I am new to drupal. I did search functionality using drupal core search but it is inefficient.Suggest me any third party search server(like apache solr) and their modules.

Answer 1

There is a list of providers on the Search API Solr Search modules page.

The Search API module module can be used with a mysql database backend which gives you the extra features of search api but unfortunatly not the speed of Solr.

Answer 2

You can also always use Google Custom Search:
