Hi all, To support Encryption at Rest, We have written a custom analyzer, that encrypts every token in the Input string and proceeds to the default indexing chain
We are using AES/CTR/NoPadding with unique Key Per User. This helps that the input string with common prefix, the encrypted strings will also get common prefix So that we can perform Prefix Query also. For example, run x5X7 runs x5X7tg== running x5X7q/nE5g== During searching, we will preprocess the query for encrypted Field before searching we can't do WildCard & Fuzzy Query Did anyone try this approach? Please post your suggestions and your tried approaches Thanks Aravinth
