• List of English Stop Words

    Stop Words are words which do not contain important significance to be used in Search Queries. Usually these words are filtered out from search queries because they return vast amount of unnecessary information. A better definition is provided below:

    “Words that do not appear in the index in a particular database because they are either insignificant (i.e., articles, prepositions) or so common that the results would be higher than the system can handle (as in the case of IUCAT where terms such as United States or Department are stop words in keyword searching.) Stop words vary from system to system. Also, some systems will merely ignore stop words where use of stop words in other systems will result in retrieving zero hits. ”

    Since I needed to use them in a project (Humboldt Diglital Library and Network), I am posting here a list of English stop words, and below a PHP array containing these words
