## Package org.apache.lucene.document Description

The logical representation of a `Document` for indexing and searching.

The document package provides the user level logical representation of content to be indexed and searched. The package also provides utilities for working with `Document`s and `IndexableField`s.

## Document and IndexableField

A `Document` is a collection of `IndexableField`s. A `IndexableField` is a logical representation of a user's content that needs to be indexed or stored. `IndexableField`s have a number of properties that tell Lucene how to treat the content (like indexed, tokenized, stored, etc.) See the `Field` implementation of `IndexableField` for specifics on these properties.

Note: it is common to refer to `Document`s having `Field`s, even though technically they have `IndexableField`s.

## Working with Documents

First and foremost, a `Document` is something created by the user application. It is your job to create Documents based on the content of the files you are working with in your application (Word, txt, PDF, Excel or any other format.) How this is done is completely up to you. That being said, there are many tools available in other projects that can make the process of taking a file and converting it into a Lucene `Document`.

The `DateTools` is a utility class to make dates and times searchable. `IntPoint`, `LongPoint`, `FloatPoint` and `DoublePoint` enable indexing of numeric values (and also dates) for fast range queries using `PointRangeQuery`
