Another problem.
Using the PerFieldAnalyzerWrapper solves the case where I have a
simple query, such as the following:
Query query = parser.parse("X");
or
Query query = parser.parse("X OR Y");
but if I use a more complex query like the following:
Query query = parser.parse("[A TO Z]");
then, again, the parser transforms the query to lowercase, as shown in
the code below.
Output is:
Query: B:[a TO z]
0 total matching documents
while I would have expected to get
Query: B:[A TO Z]
...
This means that even the KeywordAnalyzer converts A and Z to lowercase
in the range query?
Should I report this as a bug?
