Author: Filip Sergeys Email: [EMAIL PROTECTED] Message: Here are some more details about result error in php (see mail 7 feb: "small error in php script?") Search on : winter returns : 152 results Search on : timber returns : 2 results Search on : tracks returns : 10 results Search on : timber AND tracks returns : 1 result Search on : timber OR tracks returns : 11 results Search on winter NOT timber returns : 150 results => as expected 152 - 2 Search on (timber OR tracks) AND winter returns : 6 results This means that: if you search on all sites that contain the word winter but not the words timber or tracks you must receive: 152 links with winter minus 6 links because there are 6 links that contain the words winter and the word tracks or timber HOWEVER : Search on winter NOT (timber OR tracks) returns : 6 results => not as expected 152 - 6 = 146 ! this is the same result as for (timber OR tracks) AND winter. I also redid the query with: winter & ~(timber | tracks) result : An error occured at '&&' DETAILS: Platform Windows 95 and 98 and linux Redhat 6.2 Indexer: 3.1.8 Php version 3.2.1.4 Mysql on windows:3.20.25 Beta Mysql on Linux: 3.20.30 Same problem occured on all platforms. Could this be a bug? Has anybody else run similar test on accuracy and noticed the same problem?
