Hi Mat
A Document is the unit to be indexed. A Document can be a File, for example.
A Document has zero, one or more Fields. A Field represent some Document
aspect: title, content, author, etc.
When a Document is indexed, the Fields have information, data to be
indexed. These are called Terms. Example: Title="my first book", you can
index it as three terms in the Field title. title:my title:first title:book.
Then you can search over title field.
Ernesto.
