- *collectionName* : The collection containing your tag index pages. This should probably be the same as specified for the tags plugin.
- *getTagWeight* : Override the function used to generate the tag weights (see below).
- *logLevel*: Override the log level for log messages from this plugin. Defaults to 'info'.
- *getTaggedFiles*: The function to get all source files. Override the default `docpad.getFiles({tags: $has: tag})` to use only a filtered collection like `docpad.getFiles({tags: {$has: tag}, isPublished:true})`.
