How to query in solr without key

Question

I am a beginner in solr i found that the query

http://localhost:8983/solr/collection1/select?q=book%0A&wt=json&indent=true

works fine with the default collection which came along with the solr package i tried my self to create a new collection and query it my query is:

http://localhost:8983/solr/newcollection/select?q=book1&wt=json&indent=true is not working?

so how to make this query work my schema is

    <fieldType name="string" class="solr.StrField"  />
    <fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="float" class="solr.TrieFloatField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="double" class="solr.TrieDoubleField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="date" class="solr.TrieDateField" precisionStep="0" positionIncrementGap="0"/>
    <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" >
    </fieldType>

    <fieldType name="tdate" class="solr.TrieDateField" precisionStep="6" positionIncrementGap="0"/>
    <fieldtype name="binary" class="solr.BinaryField"/>

    </types>

    <fields><field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" /> <field name="title" type="text_general" indexed="true" stored="true" multiValued="false"/>
   <field name="genere" type="text_general" indexed="true" stored="true"/>
   <field name="description" type="text_general" indexed="true" stored="true" multiValued="false"/>
   <field name="comments" type="text_general" indexed="true" stored="true" multiValued="true"/>
   <field name="author" type="text_general" indexed="true" stored="true" />
   <field name="publications" type="text_general" indexed="true" stored="true" multiValued="true" />

    </fields>

We will have to define default search fields to SOLR so as to work with without specifying any fields in the query.

Define as below in solrconfig.xml

<requestHandler name="/select" class="solr.SearchHandler">
    <lst name="defaults">
         <str name="echoParams">explicit</str>
         <int name="rows">10</int>
         <str name="df">description comments </str>
    </lst>
</requestHandler>
