[opencms-dev] Opencms 7.5.2 and Lucene

[Mario Jäger]

Hi,

There are different possibilities to handle the update from the search 
indices in OpenCms:

- An index is updated automatically, when you publish a file, if the 
<rebuild> node for that index is configured with the value "auto" in the 
WEB-INF/config/opencms-search.xml

- An offline index is updated periodically, if the <rebuild> node for 
that index is configured with value "offline" in the 
WEB-INF/config/opencms-search.xml. The update frequency is configured 
global in the <offlineUpdateFrequency> node in the 
WEB-INF/config/opencms-search.xml

- An index can only be updated manually or using a scheduled job, if the 
<rebuild> node for that index is configured with value "manual" in the 
WEB-INF/config/opencms-search.xml

   * How often you update an index manually in the OpenCms search 
management (where the <rebuild> node for that index is configured with 
value "manual") is a very specific decision for every index. If you 
always want to have the index up to date, you better should configure 
the <rebuild> node with value "auto"

   * You can configure a scheduled job, which updates the configured 
indices in periodically times. Therefore, you have to use the class 
org.opencms.search.CmsSearchManager as Java class in the scheduled job. 
You have to configure the parameter "indexList" with the list of 
indices, which shall be updated, separated by the pipe symbol. If a log 
file shall be written, when updating the indices, the parameter 
"writeLog" is to configure to true

Kind Regards,
Mario.
