Can you add some comments to explain the purpose of this class. And how you set it to make it CaseSensitive?

In the KeywordSearchOpDesc, the comment mentions about the balanced performance and wide range of supported tokens for the StandardAnalyzer. How is the CaseSensitiveAnalyzer compared to StandardAnalyzer in terms of those aspects?

This PR adds an option for case sensitivity to the keyword search operator. Users can now use a checkbox to specify whether their search should be case sensitive or case insensitive.
This functionality is enabled through the addition of a CaseSensitiveAnalyzer that extends the base Lucene Analyzer for case sensitive searches, while the original StandardAnalyzer is used for case insensitive searches.
