<h1>Hyper Estraier.</h1> |
| 22 |
|
| 23 |
<div>a full-text search system for communities.</div> |
| 24 |
|
| 25 |
<h2>Introduction</h2> |
| 26 |
|
| 27 |
<p>This is a package implementing the node API of <a href="http://hyperestraier.sourceforge.net/">Hyper Estraier</a>. This is a pure java package though it is not uncertified. So, it works on Linux, Mac OS X, Windows, and so on. It does not depend on the core library of Hyper Estraier. Applications are implemented as clients of node servers running on local or remote machines.</p> |
| 28 |
|
| 29 |
<p>Though Hyper Estraier itself is released under the terms of the GNU LGPL, this package is released under the terms of a BSD-style license.</p> |
| 30 |
|
| 31 |
<h2>Setting</h2> |
| 32 |
|
| 33 |
<p>Get the JAR file `<a href="http://hyperestraier.sourceforge.net/jar/estraier.jar">estraier.jar</a>' and make the classpath include the JAR file.</p> |
| 34 |
|
| 35 |
<p>`estraier.*' should be imported in each source file of application programs.</p> |
| 36 |
|
| 37 |
<h2>Example of Gatherer</h2> |
| 38 |
|
| 39 |
<p>The following is the simplest implementation of a gatherer.</p> |
| 40 |
|
| 41 |
<pre style="margin: 0.5em 0.5em; padding: 0.1em 0.3em; border: 1pt solid #aaaaaa;">import estraier.*; |
| 42 |
|
| 43 |
public class NodeExample001 { |
| 44 |
public static void main(String[] args){ |
| 45 |
// create and configure the node connecton object |
| 46 |
Node node = new NodeImpl(); |
| 47 |
node.set_url("http://localhost:1978/node/test1"); |
| 48 |
node.set_auth("admin", "admin"); |
| 49 |
// create a document object |
| 50 |
Document doc = new DocumentImpl(); |
| 51 |
// add attributes to the document object |
| 52 |
doc.add_attr("@uri", "http://estraier.gov/example.txt"); |
| 53 |
doc.add_attr("@title", "Over the Rainbow"); |
| 54 |
// add the body text to the document object |
| 55 |
doc.add_text("Somewhere over the rainbow. Way up high."); |
| 56 |
doc.add_text("There's a land that I heard of once in a lullaby."); |
| 57 |
// register the document object to the node |
| 58 |
if(!node.put_doc(doc)) |
| 59 |
System.err.println("error: " + node.status()); |
| 60 |
} |
| 61 |
} |
| 62 |
</pre> |
| 63 |
|
| 64 |
<h2>Example of Searcher</h2> |
| 65 |
|
| 66 |
<p>The following is the simplest implementation of a searcher.</p> |
| 67 |
|
| 68 |
<pre style="margin: 0.5em 0.5em; padding: 0.1em 0.3em; border: 1pt solid #aaaaaa;">import estraier.*; |
| 69 |
|
| 70 |
public class NodeExample002 { |
| 71 |
public static void main(String[] args){ |
| 72 |
// create the node connecton object |
| 73 |
Node node = new NodeImpl(); |
| 74 |
node.set_url("http://localhost:1978/node/test1"); |
| 75 |
// create a search condition object |
| 76 |
Condition cond = new ConditionImpl(); |
| 77 |
// set the search phrase to the search condition object |
| 78 |
cond.set_phrase("rainbow AND lullaby"); |
| 79 |
// get the result of search |
| 80 |
NodeResult nres = node.search(cond, 0); |
| 81 |
if(nres != null){ |
| 82 |
// for each document in the result |
| 83 |
for(int i = 0; i < nres.doc_num(); i++){ |
| 84 |
// get a result document object |
| 85 |
ResultDocument rdoc = nres.get_doc(i); |
| 86 |
// display attributes |
| 87 |
System.out.println("URI: " + rdoc.attr("@uri")); |
| 88 |
System.out.println("Title: " + rdoc.attr("@title")); |
| 89 |
// display the snippet text |
| 90 |
System.out.print(rdoc.snippet()); |
| 91 |
} |
| 92 |
} else { |
| 93 |
System.err.println("error: " + node.status()); |
| 94 |
} |
| 95 |
} |
| 96 |
} |
| 97 |
</pre> |
