2. How to setup cron task to index content of new documents automatically

- Publish the plugin: Documents Indexer - Cron task

This plugin has various important parameters:

  • Integrate with Edocman documents Select Yes in case you want to index documents in Edocman documents folder
  • Number Documents will be indexed With each time running, Documents Indexer can't index all documents, you should enter a number of documents that component will index. Default is 5

- You should setup cron tasks from your server to call the direct links on your site by this commandBy default, Document Indexer extension uses a system plugin to trigger sending alert notifications. That mean it requires someone access to the site (search engine bots are also counted) to trigger process. Sometime, it is not reliable or causes multiple documents indexed in case your site has a very high traffic. To address that limitation, you can setup cron job from your hosting account to trigger documents indexing instead. Please see detailed instructions below: 

Setup a cron job to make a request to this URL using CURL (note that you should use the CURL so that the variable can be passed in the GET request, see https://stackoverflow.com/questions/11375260/cron-command-to-run-url-address-every-5-minutes for detailed instructions


  • Replace domain.com/ with URL of your site
  • Replace SECRETCODE with the secret string which you entered in the Trigger Code parameter of plugin

That will make the reminder only processed when there is a request made to that URL (which should be secret as no real users will access to that URL). It will make it more reliable compare to replying a system plugin.
