I've re-read the whole of this thread and the contribution docs and have come to the conclusion that there is no 'Advanced Search' facility - just the sidebox filters. Moku may have placed the search settings in the Product Type - Edit Layout page for future development, perhaps of a planned advanced search facility.

As I mentioned in my initial post I have used this contribution to upgrade an existing on-line bookshop previously installed on Zencart 1.2.5 and utilising the old 'zen_demo_book' contribution. It is now installed on zencart v 1.3.5 using this contribution. I have amended Moku's sql file to include the necessary data transfer from the old contribution tables to Moku's tables so that upgrading an existing bookshop is just a matter of following Moku's install instructions and running the modified sql. If anyone wants a copy of my modified sql file just drop me a PM.

If you are interested in seeing the contribution at work on a live bookshop you can see it here:

Only the 'Authors' sidebox filter is beiing utilised at present but it is working and all of the authors were added using the previous contribution and transferred across to the new tables as described above.
