Hi...

I have a keyword field that for example has the word 'dog' in it as
one, of say, 20 words.
I want to fetch records that contain the separate word 'dog' in this
keyword field. At the same time,
records that contain words where the string 'dog' is anywhere
embedded in the word, yet do not
contain dog as a separate word, should not be returned.
I tried the following, but got records back where 'dog' was embedded
in other words:
args.addObject("dog *"); //if dog is the first word in a set of
words
args.addObject("* dog *"); //if dog is a separate word, but not
first or last
args.addObject("* dog"); //if dog is the last word
This is ok I think.... I use the wildcard the same way and it works
fine.
EOQualifier qual = EOQualifier.qualifierWithQualifierFormat
("resourceKeywords caseInsensitiveLike %@
OR resourceKeywords caseInsensitiveLike %@
OR resourceKeywords caseInsensitiveLike %@",args);
I don't think you need all those qualifications. I think you can pass
an array of a couple arguments and make it work like
EOQual.qualWithQualFormat("ResourceKeywords caseInsensitiveLike %@",
args);
and that eof will create a qualification including all the arguments in
args. I saw this in one part of the documentation, but couldn't point
you anymore... Not in the JavaDocs. I found that part (argument
handling) not so in-depth explained. Try it out!
Question 1: Am I using the wildcard * correctly? If no, what is the
correct syntax?
Yup. Think so.
Question 2: Am I using an efficient approach for this type of search?
If no, what is
a better approach, assuming that I don't want to use
qualifyDataSource in DisplayGroups?
Thanks,
Mike W.
