The module is very simple and the large number of parameters makes it very useful.
You can for instance define a black list of common words you want to exclude and a white list of what keywords must appear. This latter is very useful for setting expressions of 2 or 3 words which can't be computed automatically.
However, I only give a 4 stars fotr this one because I have a slight problem with excluding words containing the character ' like in french word "d'un" or "c'est".
This is the only place I found to publish this bug. I didn't found a contact or support section.

I'm very impressed by the overall quality of this component, looks simple but do a lot !

Very handy and intuitive, this component perfects a features Joomla's core lacks : a good and fast way to browse through content, when traditionnal browsing or search aren't enough.

However, to fully suits my need I would expect that the module could use parameters to selects which custom property to display, so we can duplicate the module and configure them independently to fit different category thematics.

Keep up the good work :)
