How to search whole solr index?

I import data from database directly into the solr index. Now I want to search it using php-solr-client. Now I want to search it:

$offset = 0;
$limit = 10;

$queries = array(
    'details:Server'
); 

$response = $solr->search( $query, $offset, $limit );

For now I can only search when I specify the field, e.g. details. Is ther开发者_如何学Pythone a way to search all fields at a time?

If you omit the details:, doesn't it search all fields that are indexed?

Otherwise, you can always combine multiple fields in one query like this:

details:Server OR field2:Server OR field3:Server

EDIT: Regarding default field to search, specify a "dummy" field that would be populated with multiple values:

<field name="text" type="text" indexed="true" stored="false" multiValued="true"/>

Then have copyField entries for all fields that would be searched:

<copyField source="title" dest="text"/>
<copyField source="akatitle" dest="text"/>
<copyField source="year" dest="text"/>

And finally, specify that this field should be the default one:

<defaultSearchField>text</defaultSearchField>

That should work.
