This is a predictive search, so just start typing and the list of projects will automatically adjust to your search term. So it is really fast to find the project you are after, even if you have hundreds of them.
IMPORTANT NOTE: VIRTUAL FILE DIRECTORY If you wish to group your projects then this search is very helpful. Say you are doing a range of work for BMW and you have projects with them in 20 different locations. If you just name each project in the same manner then you can create a virtual file directory containing all your grouped projects. So BMW - London, BMW - Brighton, BMW - Leicester etc etc.
Then just search for BMW and all the related projects will show immediately.
Simple but powerful.
