如何连接到服务器并使用Elastic Search索引pdf文件？

Question

So I have a basic User interface I created with vaadin and the goal is to eventually have an web application that I will deploy. This application will allow users to Search, update , delete/create, add, files to folders containing pdfs that that will be indexed and categorized. In other words I'm dealing with pdfs that need to be found and open after the user's query no matter what category is present or later added dynamically by the user. There isn't much information on using Spring boot ,elastic search, and vaadin .(plus I'm still a noob ) so I'm kind of stuck.

Answer 1

ElasticSearch provide a plugin based on Apache Tika to help you to index PDF named Mapper plugin (former mapper-attachment) If you want to use Spring (not especially Spring boot), you can use Spring Data ElasticSearch but not sure that it's available for 5.X version. From my side, I prefere build my own Client API (Java) based on ElasticSearch Java API to fit my needs. I don't know vaadin....
