What about AceSearch - do you know if anyone has implemented it on jReviews?
I asked this to Acesearch team few days ago and they tell me something will available soon. However I will wait until Alejandro implement what he say that mean his own Ajax Search feature. Installing a whole component just for search is not ideal because is one more stuff to take care with his update, security and compatibility. Personally I try always to avoid to install stuff who will burdening the site for nothing.
I have a website with more than 10'000 listings and I'm under developing another who will have more than 25'000 listings. With this big amount of listing is quite difficult for users to get quickly what they want. Unfortunately The traditional search method available actually in Jreviews, Joomla and any other component is not well adapted when you have lot stuff to search...
