Is it possible to enable content searching on your website? By this, I am wondering if it is possible to search through the content of the documents uploaded into the admin file manager, or documents module, or documents library module and produce resutls from that search based on the content of the files uploaded to these three modules. If this isn't possible, does anyone know of a module in the store that may be able to do this? I've been looking for one without much luck.

I only wasn't sure about that because of this comment on p 121 of the super user manual:

At DNN Search Enabled, select from these options:
Check the check box to enable the documents to be included in the default DNN Search. The searchable fields are the Name and the Description of the document. Note: The default DNN Search
does not index document content. Also, it does not implement any kind of security. Therefore, unauthorized users may see descriptions for documents they may not have access to. Such
documents will still be download protected.
Uncheck the check box to remove this module

Despite my above comment about the Document Library module in the PE/EE, that module you listed from the store looks excellent.
