The _SiteSearchService_ component is used in the Search portlet that allows users to find all information matching with your given keyword.

It is configured in the _core/core-configuration/src/main/webapp/WEB-INF/conf/configuration.xml_ file as follows:

{code:xml}
<import>war:/conf/wcm-core/core-search-configuration.xml</import>
{code}

The component configuration maps the _SiteSearchService_ component with its own implementation: _SiteSearchServiceImpl_.

{code:xml}
<component>
  <key>org.exoplatform.services.wcm.search.SiteSearchService</key>
  <type>org.exoplatform.services.wcm.search.SiteSearchServiceImpl</type>
  <component-plugins>
    ...
  </component-plugins>
  <init-params>
    <value-param>
      <name>isEnabledFuzzySearch</name>
      <value>true</value>
    </value-param>
    <value-param>
      <name>fuzzySearchIndex</name>
      <value></value>
    </value-param>
  </init-params>
</component>
{code}
