List of noise words to skip during indexing (default: "noise.dat") A noise word is a word such as the or if that is so common that it is not useful in searches. To save time, noise words are not indexed and are ignored in index searches. 

When an index is created, dtSearch copies the list of words from noise.dat into the index directory and also builds the word list into other index files. After an index is created, subsequent changes to the noise word list will not affect indexing for that index
