The * package also provides utilities for working with {@link org.apache.lucene.document.Document}s and {@link org.apache.lucene.index.IndexableField}s.</p> * <h2>Document and IndexableField</h2> * <p>A {@link org.apache.lucene.document.Document} is a collection of {@link org.apache.lucene.index.IndexableField}s. A * {@link org.apache.lucene.index.IndexableField} is a logical representation of a user's content that needs to be indexed or stored. * {@link org.apache.lucene.index.IndexableField}s have a number of properties that tell Lucene how to treat the content (like indexed, tokenized, * stored, etc.) See the {@link org.apache.lucene.document.Field} implementation of {@link org.apache.lucene.index.IndexableField} * for specifics on these properties. * </p> * <p>Note: it is common to refer to {@link org.apache.lucene.document.Document}s having {@link org.apache.lucene.document.Field}s, even though technically they have * {@link org.apache.lucene.index.IndexableField}s.</p> * <h2>Working with Documents</h2> * <p>First and foremost, a {@link org.apache.lucene.document.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 {@link org.apache.lucene.document.Document}. * </p> * <p>The {@link org.apache.lucene.document.DateTools} is a utility class to make dates and times searchable. {@link * org.apache.lucene.document.IntPoint}, {@link org.apache.lucene.document.LongPoint}, * {@link org.apache.lucene.document.FloatPoint} and {@link org.apache.lucene.document.DoublePoint} enable indexing * of numeric values (and also dates) for fast range queries using {@link org.apache.lucene.search.PointRangeQuery}</p> */ package org.apache.lucene.document;
