Solr - How to search in all fields without passing

问题:

I have tried as below,

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

and copy all my fields to copyField as below,

<copyField source="fullname" dest="collector"/>
<copyField source="email" dest="collector"/>
<copyField source="city" dest="collector"/>

and also I have put all copyField tags below

<fields>

</fields>

tags. But I cant search in all fields. I have to pass fullname before query like,

q=fullname:Mayur

I want search by,

q=Mayur

And I should search all fields contains Mayur word.

Help me please

回答1:

make sure the fields have stored=true

<field name="field_name" type="text_general" indexed="true" stored="true"/>

True if the value of the field should be retrievable during a search.

Use the Default Search Field : The is used by Solr when parsing queries to identify which field name should be searched in queries where an explicit field name has not been used.

<defaultSearchField>collector</defaultSearchField>

in your schema.xml

This has been deprecated in solr 7: https://lucene.apache.org/solr/guide/7_0/major-changes-in-solr-7.html It's recommended to use df parameter.
