For me, the following only finds one match when run with "To be, or
not to be" (a file from Fink)... not the thousands you're getting. And
if I create only one file on my system with "Briggel and Braggel", I
get no hits for "Briggel Braggel" (and only one for the correct
phrase).
I'm not sure what's different about your code, but I suspect the
problem isn't the NSPredicate.
#include <CoreServices/CoreServices.h>
#import <Foundation/Foundation.h>
int main( int argc, const char * argv[] )
{
if (argc != 2)
{
NSLog( @"usage: %s <query>", argv[ 0 ] );
return 1;
}
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSString *value = [NSString stringWithCString:argv[ 1 ]];
NSPredicate *predicate = [NSPredicate predicateWithFormat:
@"%K LIKE[cd] %@",
kMDItemTextContent,
value];
NSMetadataQuery *query = [[NSMetadataQuery alloc] init];
[query setPredicate:predicate];
[query startQuery];
while ([query isGathering])
[[NSRunLoop currentRunLoop]
runMode:NSDefaultRunLoopMode
beforeDate:[NSDate distantFuture]];
NSUInteger count = 0;
for (NSMetadataItem *item in [query results])
{
++count;
NSLog( @"%d:", count );
for (NSString *attribute in [item attributes])
{
NSLog(
@"\t%@: %@",
attribute,
[item valueForAttribute:attribute]
);
}
NSLog(
@"\t%@: %@",
kMDItemPath,
[item valueForAttribute:(NSString*)kMDItemPath]
);
}
[pool drain];
return 0;
}
