Hi Team,
Kindly help me out with this problem. Thanks, Satyan ---- On Wed, 23 May 2018 15:01:39 +0530 Chellasamy G <chellasam...@zohocorp.com> wrote ---- Hi, Thanks for the reply. Actually I need to implement it for StringField which is non-analyzed. So, if I am not wrong I can't add the analyzer for StringField. My scenario is something similar to the one discussed in the below thread, https://discuss.elastic.co/t/es-5-0-case-insensitive-search-for-keyword-fields/64111/10 Could you please let me know how to do the same the thing in lucene.

The way to do it depends on how you are building your analyzer today (pre-built analyzer, extending Analyzer or using CustomAnalyzer). This will preserve the original case in field values because lowercasing will only be applied to the content of the inverted index, not stored fields where hits are fetched from.
