windows+php+lucene
首先你的安装配置php-java-bridge，见此贴：http://zhengdl126.iteye.com/blog/418574，最好能够理解PHP如何调用自定义的JAVA下载lucene并解压：
http://www.apache.org/dyn/closer.cgi/lucene/java/
假如我的php.ini是这样设置的
extension=php_java.dll
;java.java = "C:\jdk1.6.0_13\bin\java"
java.class.path = "D:\php\ext\JavaBridge.jar;c:\myclasses" c:\myclasses就是我存放自己的class文件地址
java.java_home = "C:\jdk1.6.0_13\jre"
java.library = "d:\jdk1.2.2\jre\bin\server\jvm.dll"
java.library.path = "D:\php\ext"
首先我要编译lucene中需要的JAVA文件：
把lucene-2.4.1-src\lucene-2.4.1\src\java 下的org目录整体编译，然后拷贝到c:\myclasses下
接着在c:\myclasses下创建 TxtFileIndexer.java

}
return result;
}
}
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
C:\myclasses>javac TxtFileIndexer.java 编译成TxtFileIndexer.class
在web下创建test.php
<?php
error_reporting(0);
java_require("C:/myclasses");
$tf = new Java('TxtFileIndexer');
$s = $tf->test();
print "TxtFileIndexer->test()<br />".$s;
echo "<hr />";
$data_path = "C:/myclasses/data/manual";
$index_path = "C:/myclasses/data/search";
if($_GET["action"] == "create")
{
$s = $tf->createIndex($index_path,$data_path);
print $s;
}else
{
echo "<form method=get> <input type=text name=w /><input type=submit value=search /><br />";
if($_GET["w"] != "")
{
$s = $tf->searchword($_GET["w"],$index_path);
print $s;
}
}
?>
最后访问test.php就可以看到正常页面。附件中有整个测试源码和编译后的JAVA文件供下载
继续完善：
对test.php做部分修改：
if($_GET["w"] != "")
{
$tf->createIndex($index_path,$data_path);//此行为增加，在$data_path目录下建立几个*.txt文件
$s = $tf->searchword($_GET["w"],$index_path);
print $s;
}
执行完了以后就可以发现$index_path目录下会增加个文件，我想 应该是建立索引的文件，但是当在页面上提交搜索的时候，却没有搜索到的字符，出现这样的内容：
[o(String):"Result:
"]
不是很了解lucene的内部原理，不知道如何改写了。明天继续。。。
