Question

I am using Apache Solr for indexing and searching. I have to give weight to the specific field so that If I make search then search has to perform on that field which is most weighted and then on others.

I am using SolrJ, Java, and GWT for development.

To boost at index time you need to supply a boost statement in your update doc.

<add overwrite="true">
    <doc boost="2.0">
        <field name="id">1234</field>
        <field name="type">type1</type>
    </doc>
    <doc>
        <field name="id">2345</field>
        <field name="type" boost="0.5">type2</type>
    </doc>
</add>

The above example demonstrates how to boost a complete document (elevation) as well as how to boost a specific field.
