I have a site that needs to have advanced search functionality. The standard Joomla search capabilities are not enough. The K2 Search plug-in allows you to search through the K2 content but I need to be able to utilise more complex searches. (e.g. Searching for an article written by a particular person on a particular date or using a K2 tag/category).

Any ideas if any of the advanced search plug-ins on offer for Joomla can work with K2 content. Can K2 categories/tags/content etc be searched for?

Exactly what I was trying to say, advanced search by field / category.

Ie book store:

Drop Down: Category (subject of book)
Text Field: ISBN
Tickbox Boolean: First Edition
etc etc

can you help me to search in k2 search box to find user?.. if i search "billy" it will be shown what k2 items that Billy has written.. thank you so much anoyone can help?.. btw k2 is very good plugin like this..:!!..:)
