basic full text search with solarium

Just trying out Solr in combination with Solarium for a search form on a website. I would like to search for a combination of words like "word1 word2 word3" in all columns, and get results sorted by the highest search score.

I successfully imported all the data in the solr database and the simple select example from solarium outputs the following:

NumFound: 21421

With a few detailed results.

As soon as i start to add the search words to the search i get 0 results. When i specify the search column like "body:word1" the search does work and returns results. am i doing something wrong in de search code or do i have my configuration wrong ?

Search code:

// create a client instance
$client = new Solarium_Client($config);

// get a select query instance
$query = $client->createSelect();
$query->setFields(array('id','title','description','body'));
#$query->setQuery("searchTerm"); //this does not work 
#$query->setQuery("body:searchTerm"); //this does work 

// this executes the query and returns the result
$resultset = $client->select($query);

// display the total number of documents found by solr
echo 'NumFound: '.$resultset->getNumFound();

You should specify the search fields. If you want to search through all the fields, then you should do this:

$query->setQuery("*:searchTerm");

Or, alternatively, you can use dismax/edismax query type:

$dismax = $query->getDisMax();
$dismax->setQueryFields('theFieldIwantToLookInto1 theFieldIwantToLookInto2');

$query->setQuery('searchTerm');
