You can configure boosts
at indexing time, for example, to boost specific properties, and at query execution to boost a specific word in the query. For more information, see http://docs.day.com/content/en/home/crx/crx141/first_steps_with_crx/searching_in_crx/0.html.
Set the boosts
at query execution in the query itself, using the ^ operator.
Example:
jcr:contains(., 'jelly sandwich^4')
In this example, the word "sandwich" has weight four times more than the word "jelly."
Configure boosts
at indexing time in the search indexing configuration file (see IndexingConfig).
Example:
Bsp indexing_config.xml:
<?xml version="1.0"?>
<!DOCTYPE configuration SYSTEM
"http://jackrabbit.apache.org/dtd/indexing-configuration-1.0.dtd">
<configuration
...
<index-rule nodeType="cq:PageContent">
<property boost="4.0">jcr:title</property>
</index-rule>
</configuration>
In this example, the property jcr:title
has weight four times more than normal properties.
Note: The boost in this case is respected only if a jcr:contains()
is done on the corresponding property, for example jcr:contains(@jcr:title, 'find this')
. If there is only a jcr:contains(., 'find this'),
the boosts
at indexing time have no effect.
Find more information about possible configurations in the search indexing configuration file on the jackrabbit wiki, see http://wiki.apache.org/jackrabbit/IndexingConfiguration. (Note: It is jackrabbit-specific and must not be absolutely equivalent in CRX!)
Note: For information on how to modify the indexing_config.xml mentioned in this article, see http://helpx.adobe.com/experience-manager/kb/SearchIndexingConfig.html.
