It is also possible to configure a boost value for the nodes that match the index rule. The default boost value is 1.0. Higher boost values (a reasonable range is 1.0 - 5.0) will yield a higher score value and appear as more relevant.

<?xml version="1.0"?>

<!DOCTYPE configuration SYSTEM "http://www.exoplatform.org/dtd/indexing-configuration-1.0.dtd">

<configuration xmlns:nt="http://www.jcp.org/jcr/nt/1.0">

  <index-rule nodeType="nt:unstructured"

              boost="2.0">

    <property>Text</property>

  </index-rule>

</configuration>

If you do not wish to boost the complete node but only certain properties, you can also provide a boost value for the listed properties:

<?xml version="1.0"?>

<!DOCTYPE configuration SYSTEM "http://www.exoplatform.org/dtd/indexing-configuration-1.0.dtd">

<configuration xmlns:nt="http://www.jcp.org/jcr/nt/1.0">

  <index-rule nodeType="nt:unstructured">

    <property boost="3.0">Title</property>

    <property boost="1.5">Text</property>

  </index-rule>

</configuration>
