Hi.

At first I was trying to find a similar problem via ez-search - but I think, it's too special. :o)

Here is the problem:
An actual content-management-system of one customer of us is realised with EZ Version 3.5.1.
Since half a year the search shows problems to find different articles.

E.g.:

1. Entries like "acs" could not be found. (There are more then 50 entries with this phrase in the cms.)
2. Entries like "spannung" or "spannung*" (this is one of the most used words in the cms) could not be found, too.

3. However phrases like "-XHV", "SRM-3000" or "high-" with special characters get a lot of hits.

The searchindex does not show any errors. It seems ok...
I don't know where I have to search?! To me, this makes no sense.

Any help greatly appreciated!

Thanks!

Steffi

Hi Stefanie

There is actually some code in the search that will exclude frequent words.

From 3.5.2

// Loop every word and insert result in temporary table

            include_once( 'kernel/classes/ezcontentobjecttreenode.php' );
            $showInvisibleNodesCond =& eZContentObjectTreeNode::createShowInvisibleSQLString( true );

            foreach ( $searchPartsArray as $searchPart )
            {
                $stopWordThresholdValue = 100;
                if ( $ini->hasVariable( 'SearchSettings', 'StopWordThresholdValue' ) )
                    $stopWordThresholdValue = $ini->variable( 'SearchSettings', 'StopWordThresholdValue' );

                $stopWordThresholdPercent = 60;
                if ( $ini->hasVariable( 'SearchSettings', 'StopWordThresholdPercent' ) )
                    $stopWordThresholdPercent = $ini->variable( 'SearchSettings', 'StopWordThresholdPercent' );

                $searchThresholdValue = $totalObjectCount;
                if ( $totalObjectCount > $stopWordThresholdValue )
                {
                    $searchThresholdValue = (int)( $totalObjectCount * ( $stopWordThresholdPercent / 100 ) );
                }

                // do not search words that are too frequent
                if ( $searchPart['object_count'] < $searchThresholdValue )

You need to tweak the StopWord settings in site.ini
See: http://ez.no/doc/ez_publish/technical_manual/3_9/reference/configuration_files/site_ini/searchsettings

Hi Bruce!

I modified it (site.ini), but the problem still exists. :o(

Hi Stefanie

Did you clear the cache?

What values have you got 'StopWordThresholdValue' & 'StopWordThresholdPercent' set to?

I believe that if you set 'StopWordThresholdValue' to a large value (say 1000000) or 'StopWordThresholdPercent' = 100 that the exclusion will not happen.

Cheers
Bruce

Hello Bruce,

thanks for your reply.

Yes, I cleared the cache. And here are the SearchSettings:

StopWordThresholdPercent = 80
StopWordThresholdValue = 100

Cheers,
Steffi
