Dear Friend,

things are actually easy to prevent this:

In Function get_temp_urls located in spider.php a sql gets executed. The results of this sql get stored in an Array named $tmp_urls.

Limit the SQL results to say 0,100 and your spider will work fine as the Array is kept small. Now, if you think the spider will stop after 100 URLs, then you are wrong, he continues way as long as there is something to spider (depending on your settings)!

The SQL I use reads:
$result = mysql_query("select link from ".$mysql_table_prefix."temp where id='$sessid' limit 0,10"winking smiley;

This also speeds up the overhead before the spider starts and limits queries against the database!
Try it and be surprised!

:-) Keep smiling!

Long URL..HELP

Would you like to show the title and the url shorter like in this URL ?

Web Developer site

edit the file /include/searchfuncs.php
near line 569


if ($title=='')
$title = $sph_messages["Untitled"];
//Start - show shorter title
$title = strlen($title) > 16 ? substr($title, 0, 10)."...".substr($title, -7):$title;
//End - show shorter title
$regs = Array();
foreach($words['hilight'] as $change) {
while (@eregi("[^\>](".$change."winking smiley[^\<]", " ".$title." ", $regs)) {
$title = eregi_replace($regs[1], "<b>".$regs[1]."</b>", $title);
}

while (@eregi("[^\>](".$change."winking smiley[^\<]", " ".$fulltxt." ", $regs)) {
$fulltxt = eregi_replace($regs[1], "<b>".$regs[1]."</b>", $fulltxt);
}
$url2 = $url;

//Code Added

if (strlen($url2) > 35) {
$url2 = substr($url2, 0, 19)."...".substr($url2, -15) ;
}

//Code Added


while (@eregi("[^\>](".$change."winking smiley[^\<]", $url2, $regs)) {
$url2 = eregi_replace($regs[1], "<b>".$regs[1]."</b>", $url2);
}
}

Automatically clean keywords?
Posted by: Tec (IP Logged)

No, during re-indexing database keywords and links are not automatically cleaned.

To clean keywords from command line use:

.../admin/admin.php?f=15

To clean links from command line use:

.../admin/admin.php?f=16

Searching dates?
Posted by: huseurdaddy2001 (IP Logged)

Hello,

Sphider cannot search dates with forward slashes (/).

For example, if I search for 04/29/07, sphider finds nothing, even though I have sites with that date.

If I edit my sites and simply replace the forward slash (/) with a hyphen (-) and re-index, then sphider finds all sites if I search for 04-29-07.

Is it possible to modify sphider such that it returns sites with slashes in date as keywords?

Open .../admin/sphiderfuncs.php

Search for:

$file = preg_replace("/[\*\^\+\?\\\.\[\]\^\$\|\{\)\(\}~!\"\/@#?$%&=`?;><:,]+/", " ", $file);

Delete this row and replace it with:

$file = preg_replace("/[\*\^\+\?\\\[\]\^\$\|\{\)\(\}~!\"@#?$%&=`?;><:,]+/", " ", $file);

This modification will let you search for 30/04/2007 and also for 30.04.2007

Integrate Spider results page
Posted by: ianmh (IP Logged)

Thought I would share with everyone how I got this to work. If you are trying to embed the engine you can, and it is pretty easy. smiling smiley

Open commonfuncs.php and change the includes array like this.

$includes = array('./include', 'include', '../include', './search/include', 'search/include', '../search/include');

Leave the old paths in too because I think this keeps the admin working.

"search" being what I called the directory sphider is in. Then change $include_dir in search.php followed by all the other directories like $template_dir, $settings_dir etc.

This worked for me. smiling smiley

Ban folders from being indexed
Posted by: Tec (IP Logged)
Date: May 02, 2007 10:31AM


If you have access to the sites to be indexed, there is another easy possibility:
Create a file named robots.txt and place it into the root-folder of your site to be indexed.
Content of robots.txt:
#
#
User-agent: *
Disallow: /admin/
Disallow: /backup/
Disallow: /folder_xyz/
#
# End of file

Now all well educated crawlers like Sphider or Google will not index these folders.
For more details see [www.robotstxt.org]

Sphider slow
Posted by: Andriko (IP Logged)
Date: April 30, 2007 08:44PM


I actually do disagree with the rest of the posts! The memorylimit has nothing to do with your timeouts! PHP by default has a script timeout limit of 30 secs. Increasing this to 60 may improve stability! You may want to look for php.ini (location varies depending on the Lamp box you are using!
Increasing PHP memory_limit as stated in a prior message is tricky! If you have way more than 1 gig you may use the 256 MB, but think of the overall load and also the database overhead when designing your memory usage map!

Searching using numbers
Posted by: Tec (IP Logged)
Date: April 30, 2007 01:20AM


Okay, here is a more intelligent solution. It lets you search for one digit numbers and leave the "Minimum word length in order to be indexed" for all other queries as you prefer.

Open /admin/spiderfuncs.php

Search for

if (strlen($element) >= $min_word_length && preg_match($pattern, remove_accents($element)) && (@ $common[$element] <> 1)) {

Delete this row and replace it with the following rows:

$int_word_length = $min_word_length;
if(preg_match("/^[0-9]{1,60}$/", $element)) {
$int_word_length = '1';
}
if (strlen($element) >= $int_word_length && preg_match($pattern, remove_accents($element)) && (@ $common[$element] <> 1)) {

Prefered results
Posted by: jhodges (IP Logged)
Date: April 27, 2007 02:07AM


Hello

Could you do this?

Create three different sphiders, and rename the sphider.php (I think that is the file that does the lifting) differently for each one. Make sure you three different categories are in three different folders, and then write 3 different robots.xt for each folder. Have each robots.txt dissallow the other two spiders, so that each spider is only spider its corresponding file.
Then when a person searches, change the submit so that it submits the keyword to each of the three seperate spiders. Maybe create a page with 3 frames to show the seperate results, or maybe change code to run the same function three times to get three different sets of results on results page? (Sorry have not thought this all the way through, but I think this is a place to start.


indexing and searching text of languages with accents
Posted by: Tec (IP Logged)
Date: April 25, 2007 01:20AM


Hi,
Independent of interface language selection, I have no problem to search for special characters and accents like ? ? ? ? ? etc.
Try the following two enhancements:

1. Change collation of the MySQL tables to utf8_bin


2. Modify of the suggest framework as described in 'Sphider Mods'

Therefore open the script

include/js_suggest/suggest.php

Search for:

print "new Array(" . implode(", ", $js_array) . "winking smiley";

and replace it with this:

print utf8_encode("new Array(" . implode(", ", $js_array) . "winking smiley"winking smiley;

Best success

Suggest Framework and problems with several letter strings
Posted by: Tec (IP Logged)
Date: March 26, 2007 03:48PM


Suggest Framework and problems with several letter strings.
Ensure that some words like Blume, Frivolit?, Horstmar and Occhi are part of your searchkeywords database. There are several others like these . . .
As admin, enable 'Enable Sphider Suggest' and 'Search for suggests in keywords'.
Now search for: blu or fri etc.
After typing the third letter my browser crashes with JavaScript Error.

Is this my personal problem or could this behavior been confirmed by anyone else?

Please do not offer a solution like 'Switch OFF error reporting in your browser', because the problems will remain.

My work around for this bug (?):
Open /include/js_suggest/suggest.php
Incude at row 25

if (ereg('blu',($_GET['q']))) // and all the other letter strings
{
$suggest_phrases = false;
$suggest_keywords = false;
}

To get no suggestion is not a solution, it's just a work around
Any SOLUTION would be appreciated.
Thanks in advance
Tec

I got the result by using utf8_bin collation for database

Framework and problems with German Umlaute

Suggest Framework and problems with German Umlaute
More than one year ago, when Sphider v.1.3.1.0 was in BETA status, this bug we already discussed in the old forum. Even in v.1.3.1.f I didn't recognize a solution for this, so with all respect to the previous work and as courteously as possible I permit myself to ask if there is (or will be) a solution for this well-known bug.
Not familiar with JavaScript I'm unable to solve this problem and need a solution from someone more intelligent than me.
My work around:
Open /include/js_suggest/suggest.php

Incude at row 24
if (ereg("?|?|?|?|?|?",($_GET['q'])))
{
$suggest_phrases = false;
$suggest_keywords = false;
}

To get no suggestion is not a solution, it's just a work around
Any SOLUTION would be appreciated.
Thanks in advance
