Abstract: Scientific research and collaboration can be performed over a network using a client device. The user generates a search query including a search term. A preliminary search result is received including one or more web documents distributed over the network in response to the search query. The preliminary search result is analyzed for additional terms, and a list of the additional terms including a frequency indication is displayed. The user can then narrow the preliminary search result to a final search result with Boolean criteria using the additional terms. The final search result is then displayed. Other features facilitate communication and collaboration among scientists to improve research and publication capabilities.
