| <div class="section"> |
| <p> |
| This document is intended as a "getting started" guide to using and running the Lucene demos. |
| It walks you through some basic installation and configuration. |
| </p> |
| </div> |
| |
| |
| |
| <a name="N1001C"></a><a name="About the Demos"></a> |
| <h2 class="boxed">About the Demos</h2> |
| <div class="section"> |
| <p> |
| The Lucene command-line demo code consists of two applications that demonstrate various |
| functionalities of Lucene and how one should go about adding Lucene to their applications. |
| </p> |
| </div> |
| |
| |
| <a name="N10025"></a><a name="Setting your CLASSPATH"></a> |
| <h2 class="boxed">Setting your CLASSPATH</h2> |
| <div class="section"> |
| <p> |
| First, you should <a href="http://www.apache.org/dyn/closer.cgi/lucene/java/">download</a> the |
| latest Lucene distribution and then extract it to a working directory. Alternatively, you can <a href="http://wiki.apache.org/lucene-java/SourceRepository">check out the sources from |
| Subversion</a>, and then run <span class="codefrag">ant war-demo</span> to generate the JARs and WARs. |
| </p> |
| <p> |
| You should see the Lucene JAR file in the directory you created when you extracted the archive. It |
| should be named something like <span class="codefrag">lucene-core-{version}.jar</span>. You should also see a file |
| called <span class="codefrag">lucene-demos-{version}.jar</span>. If you checked out the sources from Subversion then |
| the JARs are located under the <span class="codefrag">build</span> subdirectory (after running <span class="codefrag">ant</span> |
| successfully). Put both of these files in your Java CLASSPATH. |
| </p> |
| </div> |
| |
| |
| <a name="N10048"></a><a name="Indexing Files"></a> |
| <h2 class="boxed">Indexing Files</h2> |
| <div class="section"> |
| <p> |
| Once you've gotten this far you're probably itching to go. Let's <b>build an index!</b> Assuming |
| you've set your CLASSPATH correctly, just type: |
| |
| <pre> |
| java org.apache.lucene.demo.IndexFiles {full-path-to-lucene}/src |
| </pre> |
| |
| This will produce a subdirectory called <span class="codefrag">index</span> which will contain an index of all of the |
| Lucene source code. |
| </p> |
| <p> |
| To <b>search the index</b> type: |
| |
| <pre> |
| java org.apache.lucene.demo.SearchFiles |
| </pre> |
| |
| You'll be prompted for a query. Type in a swear word and press the enter key. You'll see that the |
| Lucene developers are very well mannered and get no results. Now try entering the word "string". |
| That should return a whole bunch of documents. The results will page at every tenth result and ask |
| you whether you want more results. |
