Just add google custom search onto my website. See webeyes<\/a> for more details.<\/p>\n

WordPress’ search box itself seems pretty powerless. Say I have lots of pdf files attached to my blog, wordpress can’t search the contents.<\/p>\n

Find swish-e<\/a>, which, after indexing wherever you appointed, is extremely fast to search whatever you want.<\/p>\n

Unfortunately, it seems not working for chinese. For html file, grep -r “searching words” searchingdir is ok. For pdf, still a problem.<\/p>\n

Googled a piece of php code for web-based grep search for txt or html file (not for pdf):<\/p>\n

<!DOCTYPE HTML PUBLIC “-\/\/W3C\/\/DTD HTML 3.2 Final\/\/EN”>
\n<HTML>
\n<HEAD>
\n<meta http-equiv=”Content-Type” content=”text\/html; charset=utf8″>
\n<TITLE>Search<\/TITLE>
\n<\/HEAD>
\n<BODY><\/p>\n

<?php
\n\/\/ since we use POST method, get global value into ‘test’ string
\n$test=$_POST[‘sstr’];<\/p><\/blockquote>\n

\/\/ added to scrutinize input to inhibit malicious stuff<\/p><\/blockquote>\n

$j = mb_strlen($test);
\nfor ($k = 0; $k < $j; $k++) {
\n$char = mb_substr($test, $k, 1);
\nif ($char == “;” || $char == “&” || $char == “>” || $char == “<” || $char == “|”) {
\nprint “character: $char is not allowed, try again.<br>”; exit;}
\n}<\/p>\n

\/\/ check if submit button pressed and some search value entered
\nif (isset($_POST[‘submit’]) && ! empty($test) )
\n{
\n\/\/ set file and path to search
\n$file=”txt\/” . $_POST[d_file];<\/p>\n

\/\/ check the file is readable
\nif (! is_readable ($file)) {
\nprint “ERROR accessing file $file, please contact the admin.<br>”; exit;}<\/p>\n

\/\/ build the search command
\n$cmdstr=”grep -r $test $file”;
\necho “<A href=\\”$_SERVER[PHP_SELF]\\”>Search more …<\/A>\\t”;
\necho “<p>Search results for $test in $file …<\/p>”;
\nflush();<\/p>\n

\/\/ search the file, display the result
\n$fp = popen($cmdstr . ‘ 2>&1’, ‘r’); \/\/ open proc pointer
\necho “<pre>”;
\nwhile ($buffer = fgets($fp, 4096))
\n{
\necho(“http:\/\/www.softbeam.net\/$buffer”);
\n}
\necho “<\/pre>”;
\necho “<p>END<\/p>\\n”;
\npclose($fp);
\nflush();
\nexit;
\n}<\/p>\n

?>
\n<br>
\n<h2 align=”center”>\u5168\u6587\u67e5\u8be2<\/h2>
\n<p><h4 align=”center”>
\n<form action=”<?php echo $_SERVER[‘PHP_SELF’]; ?>” method=”POST”>
\nSelect the category to search:<br>
\n<select name=”d_file”>
\n<option value=”literature\/chinese”>——all chinese literature<\/option>
\n<option value=”literature\/western”>——all western literature<\/option>
\n<option value=”literature”>——–all literature<\/option>
\n<option value=”history”>——–all history<\/option>
\n<\/select><br><br>
\n<input type=”text” name=”sstr” size=”30″ maxlength=”30″><br><br>
\n<input type=”submit” name=”submit” value=”Zzzzz”>
\n<\/form>
\n<\/h4><\/p><\/p>\n

<\/BODY>
\n<\/HTML><\/p><\/blockquote>\n

Here is another approach:<\/p>\n

Using Google Desktop Search as a network search server<\/a><\/p>\n

For windows server, it works by combination with DNKA<\/a>. For linux server,although google desktop has linux version available – GDL<\/a>, DNKA seems not linux ready.<\/p>\n","protected":false},"excerpt":{"rendered":"
