Searches are not case insensitive
Hello all,
I created the following analyzer so that clients could pose case
insensitive searches but queries are still case sensitive:
// do not tokenize any field
TokenStream t = new CharTokenizer(reader) {
protected boolean isTokenChar(char c) {
return true;
}
};
//case insensitive search
t = new LowerCaseFilter(t);
return t;
}
I use that index when I create a new instance of IndexWriter and when I use
QueryPaser, I am not sure why my searches are still case dependent.
Any help would be appreciated.
Thanks,
Rob

Ah, field NAME, not field VALUE. Normally when people refer to field
they tend to refer to field value.
Yes, field name does not get touched in an Analyzer.
I have not tested that, but apparently so (case sensitivity). Don't
worry about finding out, just use lower case field names everywhere.

Why not add print statements to your analyzer to ensure that what you
think is happening really is happening? Token has an attribute called
'text' that you could print, I believe.
