Solr field alias for indexing and querying

Question

I have a set of documents in a Solr index that have the fields, exact_title and alternative_title. I want to be able to search them by using the field title. So in other words the query title:Hello World should return documents that have an exact_title or an alternative_title "Hello World"

Is it possible to define as alias for a field during indexing time?

Answer 1

I solved defining copy fields in the schema.xml file.

Example:

<field name="title_txt" type="text_general" indexed="true" stored="false" multiValued="true"/>
<field name="exact_title_txt" type="text_general" indexed="true" stored="true" multiValued="false"/>
<field name="alternative_title_txt" type="text_general" indexed="true" stored="true" multiValued="false"/>
<copyField source="exact_title_txt" dest="title_txt"/>
<copyField source="alternative_title_txt" dest="title_txt"/>
