[Plugin: Faceted Search] smart search, collapse, page tags

Hi Andrew,

I have a few questions.

What is smart search for?
<input type=”hidden” name=”searchmode” value=”2″ />

Collapse does not work for the categories.
Do you know what the problem could be?
I did not change anything in your plugin.
Is there a Collapse function for tags?

Post Tags and Categories for Pages 1.0 Plugin
I use this plugin and most other search plugins give the search results for page tags and page categories. You plugin does not. Is there a way to let your plugin find the page results as well?
