CCH Internet Research NetWork ignores certain common words in your search expression, such as prepositions, articles, and pronouns, as well as commonly used adjectives and verbs. Words treated in this way are called "noise words."
If you use "noise words" in your search expression, the system will target phrases with the same number of words, but other words might appear in their place. Basically, the phrase that you are searching is expected to contain the same number of words, but the "noise words" are interchangeable with any other single word. It is best to avoid "noise words" because they can slow down your search and produce unexpected results.
You might consider performing a Boolean search, where you can avoid "noise words" by using the proximity connector p/n. For example, loss p/3 income.
