Lucene API Documentation</h1>
|
||||
The <a href="http://www.lucene.com">Lucene</a> API is divided into several
|
||||
packages:
|
||||
<ul>
|
||||
<li>
|
||||
<b><a href="api/com/lucene/util/package-summary.html">com.lucene.util</a></b>
|
||||
contains a few handy data structures, e.g., <a href="api/com/lucene/util/BitVector.html">BitVector</a>
|
||||
and <a href="api/com/lucene/util/PriorityQueue.html">PriorityQueue</a>.</li>
|
||||
|
||||
<li>
|
||||
<b><a href="api/com/lucene/store/package-summary.html">com.lucene.store</a></b>
|
||||
defines an abstract class for storing persistent data, the <a href="api/com/lucene/store/Directory.html">Directory</a>,
|
||||
a collection of named files written by an <a href="api/com/lucene/store/OutputStream.html">OutputStream</a>
|
||||
and read by an <a href="api/com/lucene/store/InputStream.html">InputStream</a>.
|
||||
Two implementations are provided, <a href="api/com/lucene/store/FSDirectory.html">FSDirectory</a>,
|
||||
which uses a file system directory to store files, and <a href="api/com/lucene/store/RAMDirectory.html">RAMDirectory</a>
|
||||
which implements files as memory-resident data structures.</li>
|
||||
|
||||
<li>
|
||||
<b><a href="api/com/lucene/document/package-summary.html">com.lucene.document</a></b>
|
||||
provides a simple <a href="api/com/lucene/document/Document.html">Document</a>
|
||||
class. A document is simply a set of named <a href="api/com/lucene/document/Field.html">Field</a>'s,
|
||||
whose values may be strings or instances of <a href="http://java.sun.com/products/jdk/1.2/docs/api/java/io/Reader.html">java.io.Reader</a>.</li>
|
||||
|
||||
<li>
|
||||
<b><a href="api/com/lucene/analysis/package-summary.html">com.lucene.analysis</a></b>
|
||||
defines an abstract <a href="api/com/lucene/analysis/Analyzer.html">Analyzer</a>
|
||||
API for converting text from a <a href="http://java.sun.com/products/jdk/1.2/docs/api/java/io/Reader.html">java.io.Reader</a>
|
||||
into a <a href="api/com/lucene/analysis/TokenStream.html">TokenStream</a>,
|
||||
an enumeration of <a href="api/com/lucene/analysis/Token.html">Token</a>'s.
|
||||
A TokenStream is composed by applying <a href="api/com/lucene/analysis/TokenFilter.html">TokenFilter</a>'s
|
||||
to the output of a <a href="api/com/lucene/analysis/Tokenizer.html">Tokenizer</a>.
|
||||
A few simple implemenations are provided, including <a href="api/com/lucene/analysis/StopAnalyzer.html">StopAnalyzer</a>
|
||||
and the grammar-based <a href="api/com/lucene/analysis/standard/StandardAnalyzer.html">StandardAnalyzer</a>.</li>
|
||||
|
||||
<li>
|
||||
<b><a href="api/com/lucene/index/package-summary.html">com.lucene.index</a></b>
|
||||
provides two primary classes: <a href="api/com/lucene/index/IndexWriter.html">IndexWriter</a>,
|
||||
which creates and adds documents to indices; and <a href="api/com/lucene/index/IndexReader.html">IndexReader</a>,
|
||||
which accesses the data in the index.</li>
|
||||
|
||||
<li>
|
||||
<b><a href="api/com/lucene/search/package-summary.html">com.lucene.search</a></b>
|
||||
provides data structures to represent queries (<a href="api/com/lucene/search/TermQuery.html">TermQuery</a>
|
||||
for individual words, <a href="api/com/lucene/search/PhraseQuery.html">PhraseQuery</a>
|
||||
for phrases, and <a href="api/com/lucene/search/BooleanQuery.html">BooleanQuery</a>
|
||||
for boolean combinations of queries) and the abstract <a href="api/com/lucene/search/Searcher.html">Searcher</a>
|
||||
which turns queries into <a href="api/com/lucene/search/Hits.html">Hits</a>.
|
||||
<a href="api/com/lucene/search/IndexSearcher.html">IndexSearcher</a>
|
||||
implements search over a single IndexReader.</li>
|
||||
|
||||
<li>
|
||||
<b><a href="api/com/lucene/queryParser/package-summary.html">com.lucene.queryParser</a></b>
|
||||
uses <a href="http://www.suntest.com/JavaCC/">JavaCC</a> to implement a
|
||||
<a href="api/com/lucene/queryParser/QueryParser.html">QueryParser</a>.</li>
|
||||
</ul>
|
||||
To use Lucene, an application should:
|
||||
<ol>
|
||||
<li>
|
||||
Create <a href="api/com/lucene/document/Document.html">Document</a>'s by
|
||||
adding
|
||||
<a href="api/com/lucene/document/Field.html">Field</a>'s.</li>
|
||||
|
||||
<li>
|
||||
Create an <a href="api/com/lucene/index/IndexWriter.html">IndexWriter</a>
|
||||
and add documents to to it with <a href="api/com/lucene/index/IndexWriter.html#addDocument(com.lucene.document.Document)">addDocument()</a>;</li>
|
||||
|
||||
<li>
|
||||
Call <a href="api/com/lucene/queryParser/QueryParser.html#parse(java.lang.String)">QueryParser.parse()</a>
|
||||
to build a query from a string; and</li>
|
||||
|
||||
<li>
|
||||
Create an <a href="api/com/lucene/search/IndexSearcher.html">IndexSearcher</a>
|
||||
and pass the query to it's <a href="api/com/lucene/search/Searcher.html#search(com.lucene.search.Query)">search()</a>
|
||||
method.</li>
|
||||
</ol>
|
||||
Some simple examples of code which does this are:
|
||||
<ul>
|
||||
<li>
|
||||
<a href="../demo/FileDocument.java">FileDocument.java</a> contains
|
||||
code to create a Document for a file.</li>
|
||||
|
||||
<li>
|
||||
<a href="../demo/IndexFiles.java">IndexFiles.java</a> creates an
|
||||
index for all the files contained in a directory.</li>
|
||||
|
||||
<li>
|
||||
<a href="../demo/DeleteFiles.java">DeleteFiles.java</a> deletes some
|
||||
of these files from the index.</li>
|
||||
|
||||
<li>
|
||||
<a href="../demo/SearchFiles.java">SearchFiles.java</a> prompts for
|
||||
queries and searches an index.</li>
|
||||
</ul>
|
||||
To demonstrate these, try:
|
||||
<blockquote><tt>F:\> <b>java demo.IndexFiles rec.food.recipes\soups</b></tt>
|
||||
<br><tt>adding rec.food.recipes\soups\abalone-chowder</tt>
|
||||
<br><tt> </tt>[ ... ]
|
||||
<p><tt>F:\> <b>java demo.SearchFiles</b></tt>
|
||||
<br><tt>Query: <b>chowder</b></tt>
|
||||
<br><tt>Searching for: chowder</tt>
|
||||
<br><tt>34 total matching documents</tt>
|
||||
<br><tt>0. rec.food.recipes\soups\spam-chowder</tt>
|
||||
<br><tt> </tt>[ ... thirty-four documents contain the word "chowder",
|
||||
"spam-chowder" with the greatest density.]
|
||||
<p><tt>Query: <b>path:chowder</b></tt>
|
||||
<br><tt>Searching for: path:chowder</tt>
|
||||
<br><tt>31 total matching documents</tt>
|
||||
<br><tt>0. rec.food.recipes\soups\abalone-chowder</tt>
|
||||
<br><tt> </tt>[ ... only thrity-one have "chowder" in the "path"
|
||||
field. ]
|
||||
<p><tt>Query: <b>path:"clam chowder"</b></tt>
|
||||
<br><tt>Searching for: path:"clam chowder"</tt>
|
||||
<br><tt>10 total matching documents</tt>
|
||||
<br><tt>0. rec.food.recipes\soups\clam-chowder</tt>
|
||||
<br><tt> </tt>[ ... only ten have "clam chowder" in the "path" field.
|
||||
]
|
||||
<p><tt>Query: <b>path:"clam chowder" AND manhattan</b></tt>
|
||||
<br><tt>Searching for: +path:"clam chowder" +manhattan</tt>
|
||||
<br><tt>2 total matching documents</tt>
|
||||
<br><tt>0. rec.food.recipes\soups\clam-chowder</tt>
|
||||
<br><tt> </tt>[ ... only two also have "manhattan" in the contents.
|
||||
]
|
||||
<br> [ Note: "+" and "-" are canonical, but "AND", "OR"
|
||||
and "NOT" may be used. ]</blockquote>
|
||||
The <a href="../demo/IndexHTML.java">IndexHtml</a> demo is more sophisticated.
|
||||
It incrementally maintains an index of HTML files, adding new files as
|
||||
they appear, deleting old files as they disappear and re-indexing files
|
||||
as they change.
|
||||
<blockquote><tt>F:\><b>java demo.IndexHTML -create java\jdk1.1.6\docs\relnotes</b></tt>
|
||||
<br><tt>adding java/jdk1.1.6/docs/relnotes/SMICopyright.html</tt>
|
||||
<br><tt> </tt>[ ... create an index containing all the relnotes ]
|
||||
<p><tt>F:\><b>del java\jdk1.1.6\docs\relnotes\smicopyright.html</b></tt>
|
||||
<p><tt>F:\><b>java demo.IndexHTML java\jdk1.1.6\docs\relnotes</b></tt>
|
||||
<br><tt>deleting java/jdk1.1.6/docs/relnotes/SMICopyright.html</tt></blockquote>
|
||||
HTML indexes are searched using SUN's <a href="http://jserv.javasoft.com/products/webserver/index.html">JavaWebServer</a>
|
||||
(JWS) and <a href="../demo/Search.jhtml">Search.jhtml</a>. To use
|
||||
this:
|
||||
<ul>
|
||||
<li>
|
||||
copy <tt>Search.html</tt> and <tt>Search.jhtml</tt> to JWS's <tt>public_html</tt>
|
||||
directory;</li>
|
||||
|
||||
<li>
|
||||
copy lucene.jar to JWS's lib directory;</li>
|
||||
|
||||
<li>
|
||||
create and maintain your indexes with demo.IndexHTML in JWS's top-level
|
||||
directory;</li>
|
||||
|
||||
<li>
|
||||
launch JWS, with the <tt>demo</tt> directory on CLASSPATH (only one class
|
||||
is actually needed);</li>
|
||||
|
||||
<li>
|
||||
visit <a href="../demo/Search.html">Search.html</a>.</li>
|
||||
</ul>
|
||||
Note that indexes can be updated while searches are going on. <tt>Search.jhtml</tt>
|
||||
will re-open the index when it is updated so that the latest version is
|
||||
immediately available.
