14.1.2 Ability to filter and refine queries
After running a particular query in ISI's WoS, you can further refine the results by excluding any specific instances of the bibliometric fields. You can exclude for instance editorials and book reviews from the publications or restrict the results to publications in specific years (that do not have to be consecutive). You can also restrict results to specific disciplines only or exclude specific source titles. This ensures that your final search result is likely to be exactly what you are looking for.
Unfortunately, these searches can be quite cumbersome and slow to execute as they involve clicking through multiple screens and options. In addition, ISI's user interface is not particularly intuitive and its help file very concise.
