Stopwords are frequently used words such as articles
(e.g., a, an, the), prepositions (e.g., of, in, for, through), and pronouns (e.g.,
it, their, his). Stopwords should not be included in title
word search phrases (while in Hot Papers or Highly Cited Papers) and topic
search phrases (while in Research Fronts).
When a search query includes a stopword it may return
no results or incomplete results. Try the same search excluding the stopwords,
or search on a single term instead of a phrase.
The following words are stopwords. Note that this
list is subject to change.
