This one also works for me. Only it kind of works too well, finding
thousands of files.
Another example: <kMDItemTextContent LIKE "Briggel Braggel"> finds
".../Test.txt" which only contains the line: "Briggel and Braggel" .
But I really want only files which contain "Briggel Braggel" or
"the Briggel
Braggel of today".
Are you using Tiger?
Yes, I am.
Spotlight indexes on words in Tiger; phrase
indexing began in Leopard -- the phrase must be enclosed within
quotation marks, IIRC (i.e. @"%K LIKE \"%@\"")
string = <Briggel Braggel> (without the "<>")
predicateFormatContent = @"kMDItemTextContent like %@";
predicate = <kMDItemTextContent LIKE "Briggel Braggel">
finds "Briggel and Braggel". Bad
string = <"Briggel Braggel"> (Note: " part of string)
predicateFormatContent = @"kMDItemTextContent like %@";
predicate = <kMDItemTextContent LIKE "\"Briggel Braggel\"">
also finds "Briggel and Braggel". Bad
string = anything
predicateFormatContent = @"kMDItemTextContent like \"%@\""; or:
predicateFormatContent = @"kMDItemTextContent like \'%@\'"; or:
predicateFormatContent = @"kMDItemTextContent like '%@'";
predicate = <kMDItemTextContent LIKE "%@">
finds nothing. Also not good. (There are lots of files containing %@
though).
string = <'Briggel Braggel'> (Note: ' part of string)
predicateFormatContent = @"kMDItemTextContent like %@";
predicate = <kMDItemTextContent LIKE "'Briggel Braggel'">
finds nothing. Still bad.
Now I do not have any more ideas.
Anyone else? Finding a string containing blanks on Tiger?
Kind regards,
Gerriet.
