What is the difference between word-indexed versus phrase-indexed?
When searching it is important to be aware of which fields are word-indexed versus phrase-indexed. When searching for a term in a word-indexed field, individual words and groups of words may be searched anywhere in the field. On the other hand, when searching for a term in a phrase-indexed field, the entire contents of a phrase-indexed field are searched as a whole, although truncation may be applied in a search. Individual words cannot be searched.
