回答1:

Use copyField

Here is how you can use this:

• Make all the field stored="true" and indexed="false"
• Also create a new field say cffield with multiValued="true", stored="false" and indexed="true"

Example Schema :

<field name="field1" type="string" indexed="false" stored="true"/>
<field name="field2" type="string" indexed="false" stored="true"/>
<field name="field3" type="string" indexed="false" stored="true"/>
....
<field name="cffield" type="string" indexed="true" stored="false" multiValued="true"/>

• Now all the field from you want to search, set source value of use copyField tag to copy from source field to dest

Example Schema :

<copyField source="field1" dest="cffield"/>
<copyField source="field2" dest="cffield"/>
....

Now you can search using

query = cffield:txtSearch

This will give you result from all the field you use copyField's source and cffield as dest

回答2:

indexed="false" needs to be mentioned in the schema.xml.

Once you modify the schema.xml, you need to re-index the data.(you need to re-start the server as well)

Then solr will not search in the fields which are not indexed. And if you want to search in specific field you can use the field name and the search value for the field.

like

   `q=field1:"value1"`
    q=field1:value1 OR field2:value2
    q=field1:value1 AND field2:value2
    q=value1&fq=field2:value2&fq=field3:value3
