Hi there,
If I have:
searchString = '*' + input + '*';
new EOKeyValueQualifier( anAttribute,
EOQualifier.QualifierOperatorCaseInsensitiveLike, searchString );
And someone puts in some strange characters (e.g., "find[me"), I get
the following exception.
java.lang.IllegalArgumentException: Bad pattern *photogra[hy*for

I thought EOF would escape things automatically, but perhaps there's
a bug there(?). How else might I escape the chars (WO5.3.3)?
I think you have stumbled across an undocumented feature of
CaseInsensitiveLike. I don't know what [...] might get interpreted
as, but it seems to mean something. I don't know of any way to escape
these magic characters in the qualifier value.
