Question about Case Sensitive?!

[Gong Li <ee...@gmail.com>]

Hi,

I use standardAnalyzer, queryParser, highlighter in my program, but they
lowercase the keywords. Now i need to search the keywords CASE SENSITIVE. Is
there any methods to achieve this and also use standardAnalyzer and
queryParser? Or some other ways? HOW???

Thx.

Hi Gong Li,

You can create your own Analyzer that does not add LowerCaseFilter to the
FilterChain. To achieve this, use the source code from Lucene source, rename
the class (e.g. org.yourpackage.NoLowercasingStandardAnalyzer) and remove
LowerCaseFilter from the tokenStream() and reuseableTokenStream() factory
methods.
