edocman 1.6.6

Hello everyone and Tuan in particular. I bought several versions of edocman including the latest version 1.6.6 that works great. For incredible reasons I lost my site and I'm configuring edocman again but I do not work the plugin to search for keywords in pdf files. I installed the plugin (plug_edocmanindexer) and enabled, I put the documents back but when I use the form for the search it does not find anything. Where do I make the mistake?

Hi Diego,
Once you installed and published the plugin: Edocman indexer, you can index content of your existing documents (in Edocman extension) before you can search content of those documents from database.
Thanks
Dam
