I have never done this, but you should be able to set this up in
EOModeler. Add a new Attribute named simpleSearch, make it Derived
instead of Column. Define it as
COALESCE( author, '') || COALESCE( title, '')
and mark it as read only. You can get rid of the method below and
your existing search should work.

I am using DisplayGroups which make queries on individual

I would like to provide a simple search where one text field
returns a search on a concatenation of several attributes of the
entity. I just tried putting the following code in my EO to try
this concept out (title and author are attributes in the entity):
public String simpleSearch() {
String author = author();
String title = title();
String simpleSearch;
if ((author != null) && (!author.equals(""))) {
simpleSearch = author + " " + title;
}
else {
simpleSearch = title;
}
return simpleSearch;
}
When I try and do a queryMatch on the simpleSearch field I get an
error:
java.lang.IllegalStateException: sqlStringForKeyValueQualifier:
attempt to generate SQL for
com.webobjects.eocontrol.EOKeyValueQualifier (simpleSearch
caseinsensitivelike '*test*') failed because attribute identified
by key 'simpleSearch' was not reachable from from entity 'Document'
I assume this is because the attribute "simpleSearch" is not
actually in the database. Is there a better strategy for searching
concatenated fields using DisplayGroups?
Thanks,
David
