This product works really well and I was able to index some 40 PDF files for searching. The indexing is a very easy process and worked flawlessly. I did have some problems configuring the software but their support responded quickly and resolved the problems which very very minor in the end. Overall an excellent Joomla extension.
I'm a Joomla novice and was having a very difficult time setting up a custom 404 error page. I found the Qlue Custom 404 Pro extension, downloaded it and installed it in a very short time. It did an excellent job for me and was very easy to set up.
