I just used apachesolr_multisitesearch and it worked excellently.
You will need to install drupal.org/project/apachesolr first, and then configure apachesolr_multisitesearch to work with it.

The latter extends the basic apachesolr module, which is based on apache solr.
So, the first thing you will need to do is install apache solr on your system, or whichever system you would like to act as your apache solr server. (Yes, it can be the same server as you host your site.

Read the documentation, especially if you are new to Drupal and Apache Solr. The instructions are pretty clear as to how to set everything up.

Hope this helps.

apachesolr_multisitesearch is what's used on drupal.org. You might start there.

Hi,

I need a multi-site search system but I am new in Drupal search. Firstly I tried http://drupal.org/project/multisite_search however it didn't work well, some words wasn't indexed. So I began to planning on setting up SOLR in order to use http://drupal.org/project/apachesolr_multisitesearch. (Google option is not sutiable for us.) Then I notice that there is a module such as http://drupal.org/project/nutch. So I am confused.

Is there anybody who could explain difference between these modeule (even pure SOLR search)? I am also open to any suggestion about search, any module, SOLR w/o Drupal modules, any other search options...

Thank you all in advance...
