Deciding on a CMS for a university research project website: Wordpress, Joomla, or Drupal?
I am designing and developing a website for a university research project about the natural and human history of a particular geographic area. Here is an example
of a similar type of website. The website will allow searching and browsing of a media archive (historical maps, photos, documents, and so on), with features such as advanced search, guides for teachers, an interactive map, a timeline, and so on. The website will be powered by a CMS which a small team of researchers will use to add content to the website. But which CMS?
I have extensive experience developing websites that use Wordpress as a CMS, and am considering using it for this project. I think the research team would appreciate Wordpress's easy-to-use interface. However, I am wondering if there is any compelling reason why I would be better off using Joomla or Drupal for this project. I have not used either before although I learn new systems fairly easily, and have enough time to do so. I am not considering other CMSes besides these three, as if I am going to learn a new system, I want it to be Joomla or Drupal.
My main issue with Wordpress is that the built-in search is hopelessly inadequate for this project, and so far I've been unable to find any plugins which are much better.
To sum up: Can Wordpress work for this project, or should I use Joomla or Drupal?
Thanks. As a small add-on, I am also interested in finding more examples of research websites such as the one I linked to above.
