First, I want to apologize in advance if I don't ask the question in a way you would understand better, but I'm junior programmer and I have this heavy task (my head is gonna explode), so I don't know better even if I wanted to.
So, we have our software, project where we use Spring Boot 1.5 and the data from SQL server (we are using DAO, Mapper, Xml system). Because of the Spring Boot 1.5, I can't use ES 6 and my boss told me to use ES 2.4.0 and Transport Client.
I can't find a way (to do all in this java project) where I will index some sql tables (probably using their DAO ) and later create methods for searches as well.
Which material or guides I should use? If you need any more info, please let me know.
Thank you very, very much.
