Stop-words are defined as non-information-bearing words. Words such as the, and, a, is, and on are on the stop-word list. When indexing and searching, these words will be ignored. Each language has its own stop-word list. In order to save disk space, or to speed up search results and provide a better search relevance, most search engines do not consider these common words.
The stop-words .xml for each language can be accessed under
Windows: Applications > Searchblox Server > webapps > stopwords.
