It's not clear to me that this is entirely accurate (Google, for example, is

don't think web search engine front ends are particularly relevant in any case.

With a 'AND' default 'OR' would have to be explicit. Example: 'dog cat' = 'dog

Is there still no solution for this? Every large searchengine works like
this.
Why do you *need* this? More to the point, why should mysql do this?
Honestly, I think you are confusing the user interface, the application, and
the back end. Your user interface is free to include a search box where the
user can type 'dog cat' with the expectation that only documents containing
both (AND) will be returned. Your application needs to parse the request
and send the proper query to mysql (the back end). Mysql is just a useful
tool. It stores your data and provides various forms of full-text searching:
Relevance scoring -
WHERE MATCH (doc, description) AGAINST ('dog cat')
OR searches -
WHERE MATCH (doc, description) AGAINST ('dog cat' IN BOOLEAN MODE)
AND searches -
WHERE MATCH (doc, description) AGAINST ('+dog +cat' IN BOOLEAN MODE)
Given these choices, I'm not sure what difference it makes what the default
is. You surely don't propose to pass unmodified user input to mysql, as
that's not a good idea (see SQL injection
http://www.google.com/search?q=SQL+injection). If you want AND searches,
simply have your app add the + signs to the user input as it builds the
query to send to mysql.
If you are determined to change mysql's default behavior, then Sergei has
already given a solution earlier in this thread: swap the '+' and ' ' in the
ft_boolean_syntax variable. The only objection raised to this was the
suggestion that if the user prepends a '+' to a word, it becomes optional
(OR instead of AND), but that's a moot point, as your app will, of course,
strip the '+' when parsing the user's input.

Re: Please help me: Boolean fulltext searches, AND instead of OR
I couldn't find much on the variable you were trying to change.
Although it may have changed and now be called ft_boolean_syntax. But
that still won't help you since it doesn't appear to have an option to
change the default separator.
I think you will need to add the + to each word if you want the AND
behavior. Why are you so averse to parsing? It would make it easier for
the user to input search terms.
If it's helpful, below is some php code I use for parsing search
phrases entered by users. It adds + and * based on quotes or
independent words. I wrote it a long time ago and it problem needs to
be looked at to make it better, but it's worked for me for a while now.
It will give you the AND behavior you are looking for.
function prepFullTextSearch($searchVal) {
//Split words into list
$word_List = explode(' ',trim($searchVal));
//Step through word list to get search phrases
$i = 0;
$isPhrase= false;
foreach($word_List as $word) {
$searchItems[$i] = trim( ($isPhrase?$searchItems[$i].' '.$word:$word)
);
//Check for start of Phrase
if(substr($searchItems[$i],0,1) == '') {
$isPhrase = true;
}
//If not building a phrase, append wildcard (*) to end of word
if(!$isPhrase) {
$searchItems[$i] .= '*';
$i++;
}
//Check for end of Phrase
if(substr($searchItems[$i],-1) == '') {
$isPhrase = false;
$i++;
}
}
$searchVal= '+'.implode(' +',$searchItems);
return $searchVal;
}

I found this:
set-variable = ft_boolean_default='AND'
SET ft_boolean_default = 'AND'
But it does not work, everything would be sooo much easier if this was
possible.
black cat is only an example and the real query comes from user
input. So it can be anything like +cat -dog +big nose -horse white
black -red
so parsing the input is not what i want, i just want to change the
default word separator to AND instead of OR.
Now i´m running 4.1.10 and also tried with 4.0.24
Please help me, there must be a way to change this?!?!

Re: Please help me optimize a MySQL server.
Something that small shouldn't really need optimizing. What is the size of your data (mb?, gb?) and what does your query look like? If you are doing a wild card search on a large text field without a full text index, then those times may be the best you're going to get. Many times it's about optimizing your query statement or you indexes rather than MySQL settings. For instance, I have a test machine (Mac G4 400Mhz, 512MB, MySQL 4.0.18) that does a three table join with each table having just over 100,000 rows. My initial query took about 12 seconds, but changing my query statement around a little I got it to just under 1 second. Which is pretty good considering the hardware it's on. What does you explain for the query look like? It's probably doing a full table scan, which means you're bottleneck is the disk.

Re: Please help me optimize a MySQL server.
I wouldn't upgrade until you know where the bottleneck is (CPU, disk, network, or RAM). Since you are using professional software, I wouldn't try to change the queries. Have you made changes to your my.cnf file? Since you have enough ram to hold all the data, ram is probably not your bottleneck. The question is whether you have your system configured to use it. I forget if phpbb and phpnuke use PEAR::DB to access the underlying database. If they do, there is a certain amount of overhead involved that you just can't get around without changing the database access code to use native calls. Are your database and web server on the same machine (a security no-no, but performance yes-yes)? If they are on separate machines, make sure you have a fast connection between them, at least 100MB and make sure it's full duplex.

I can say from eperience, the phpBB code is kinda bad in regards to how it talks to mysql, on some pages it is not at all uncommon for there to be 10 or more complex querries. I would be willing to bet there are many installed mods on phpBB, they offer stuff like, show all online users which though a nice feature, is heavy on the DB. There are hundreds of these mods, people just copy and paste and install them, before they know it the database is taking 30 selects on every single page load, just so you can say happy birthday to: someuser on every page. -- - Scott HanedaTel: 415.898.2602 http://www.newgeo.com Fax: 313.557.5052 [EMAIL PROTECTED]Novato, CA U.S.A. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: Please help me!
As this is really a PHP specific question, you may get a better response on the PHP
general mailing list at http://www.php.net/mailing-lists.php
Anyway, if my limited experience in PHP serves correctly, you may need to call
echo(mysql_error()); near the potentially troublesome code.

RE: please help me
Although this is not a php list...
mysql_connect() returns TRUE on success and FALSE on
failuer, so testing $link like if($link) means it
did connect.
your script should read:
$link=mysql_connect(localhost)
// the !(bang as it is called) means NOT
// so !TRUE == FALSE
if(!$link) {
printf(Could not connect to mysql server: %s,mysql_error());
} else {
//connection is good
}
or, better yet:
if(!$link=mysql_connect(localhost)) {
printf(Could not connect:\n%s :
%s\n,mysql_errno(),mysql_error());
} else {
//connection is good
}
hope it helps.

This is my php script: $link=mysql_connect(localhost); if($link) die(Couldn't connect to mysql.mysql_error() ); Perhaps you meant if(!$link) ... Notice the not ! operand. If a link is established then the $link PHP variable will no longer hold the empty string. In PHP all varaibles are automatically initialized to hold an empty string which can also be used interchangeably with the boolean false value. The standard way of connecting is: $link = mysql_connect($db_host, $db_user, $db_pass) OR die(Could not connect to database server.); Here the stuff after OR is executed only if mysql_connect returns false which is the way the C || operator works.

Re: Please help me finding a sql-statement
HI, If I understand your question, you need two queries: select count(*) as count, ip, value from log group by ip select count(*) as count, ip, value from log group by ip,value that leads to the right direction! thanks! It shows me a the ips with their values and how many times they are in the table. That brings me somehow nearer to the solution but I am still getting mad about not finding exactly what I need (you know that feeling? its like having jam in the head!) I want to get the number of rows which have the same ip and same/different value. The questions are: 1. How many rows have same values for field x and y? 2. How many ips have different values for field x (and same field y)? (more interesting) Lets have a test-table: id value timestamp 1 a 1 a 2 a 2 b 3 a 3 a 3 b The queries should return in this case: 1. 4 rows (have same id/value) 2. 2 (ids have different values for for field 'value') As I am seeking differences here, after this it will be interesting to see a list of this 2 ids and their values: id val 2 a 2 b 3 a 3 b So I could make it to: There are 2 different values for id "2" : a,b There are 2 different values for id "3" : a,b Maybe you got an idea? Many thanks for your attention! A small table for testing: CREATE TABLE test ( id tinyint(1) DEFAULT '0' NOT NULL, value char(1) NOT NULL ); # # Dumping data for table 'test' # INSERT INTO test VALUES ( '1', 'a'); INSERT INTO test VALUES ( '1', 'a'); INSERT INTO test VALUES ( '2', 'a'); INSERT INTO test VALUES ( '2', 'b'); INSERT INTO test VALUES ( '3', 'a'); INSERT INTO test VALUES ( '3', 'a'); INSERT INTO test VALUES ( '3', 'b'); - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
