Stop word file

The stop word file, [ir_languagefiles_path]<language>.stp, contains a list of words used too frequently to index because that would hinder the identification of documents. Edit this list as you would a text file. Type each word on a separate line.

The words in the file go through a stemming process, which eliminates the need to specify all the forms for the word. For example, in English, you do not have to enter both "go" and "going" into the stop words file because the stemming algorithm changes "going" to "go." The only word that must be entered in the .STP file is the word "go."
