How to have a view field that searches node title, body and everything about node
You could try using Apache Solr backend. You can use the following modules:


http://drupal.org/project/search_api
http://drupal.org/project/apachesolr


Another solution is to use a module like "views_or" or "views_filters_populate".

Otherwise you could give a try to "search_autocomplete".

Good work!
