I have to learn in context of lucene, but firstly, I want to learn the example indexing in general.
Sth like this-:
And I am not getting any google books and pdfs to learn about these topics. I basically need to learn basics of indexing and searching,indexing with lucene full process in detail, elastic search etc. I haven't googled elastic search yet, but I am not finding much information for the first twos. I believe I am not hitting the right google query. Any feedback would be really helpful as we don't have official textbook here and this topic I haven't seen in many general big data books as well.
