Search over all fields on Solr

Question

I'm trying to implement search over all fields on Solr. Exhttp://localhost:8983/solr/sample-items/select?q=oscar but no result returns. However, If I specify the field it works fine Ex http://localhost:8983/solr/sample-items/select?q=name:oscar

I try to use copyField like following but not working: on managed-schema file

  <field name="Designation" type="text_general" stored="true"/>
  <field name="Location" type="text_general" stored="true"/>
  <field name="_root_" type="string" docValues="false" indexed="true" stored="true"/>
  <field name="_version_" type="plong" indexed="false" stored="true"/>
  <field name="age" type="plongs" stored="true"/>
  <field name="id" type="string" multiValued="false" indexed="true" required="true" stored="true"/>
  <field name="name" type="text_general" stored="true"/>
  <field 
    name="_text_" 
    type="text_general" 
    indexed="true" 
    stored="true" 
    multiValued="true"
  />
.
.
.

<fields>
  <copyField source="Designation" dest="_text_" maxChars="256"/>
  <copyField source="name" dest="_text_" maxChars="256"/>
  <copyField source="Location" dest="_text_" maxChars="256"/>
</fields>

on solrconfig.xml file

  <lst name="defaults">
      <str name="echoParams">explicit</str>
      <int name="rows">10</int>
    </lst>

  <initParams path="/update/**,/query,/select,/tvrh,/elevate,/spell,/browse">
    <lst name="defaults">
      <str name="df">_text_</str>
    </lst>
  </initParams>

Any advice?

To be able to search from >1 fields (or over all fields) by default , you need to perform following two configurations.

In schema file (e.g. managed_schema) create copy field and copy other field's data into this copy field. Example is as follows.

... <field name="_text_" type="text_general" multiValued="true" indexed="true" stored="false"/> ... <copyField source="directed_by" dest="_text_" maxChars="256"/> <copyField source="genre" dest="_text_" maxChars="256"/> ...

In solrconfig.xml , update initiParam tag to make above created copy field as default search field for search handlers. Example is as follows.

<initParams path="/update/**,/query,/select,/tvrh,/elevate,/spell,/browse"> <lst name="defaults"> <str name="df">_text_</str> </lst> </initParams>

Sample Query and output :

ShubhangiP:~ spardeshi$ curl -XGET http://localhost:8983/solr/films/select?q=Gary { "responseHeader":{ "status":0, "QTime":0, "params":{ "q":"Gary"}}, "response":{"numFound":1,"start":0,"docs":[ { "id":"/en/45_2006", "directed_by":["Gary Lennon"], "initial_release_date":"2006-11-30T00:00:00Z", "genre":["Black comedy", "Thriller", "Psychological thriller", "Indie film", "Action Film", "Crime Thriller", "Crime Fiction", "Drama"], "name":".45", "_version_":1645282402834055168}] }}

From details provided in question, in managed_schema file collector field is used as copy field for three other fields named Designation , Name and Location.

But not sure if you made collector field as default search field.
