Rename index to products

In some old videos, you still using the index named as product instead of products. As the video that shows the creation of the index uses the name products, I think it make sense to use this same name in all examples.

logstash

I am sorry, I am getting little off the topic.
I was trying to parse input using csv filter in logstash.
I am getting output from logstash something like this:

hostname => "hostname=test_machine"
event_id => "event_id=1145"

How do I exclude the hostname= or Is there a better way to use hostname inside quotation as a field. Please help

I used
csv {
autogenerate_column_names => "false"
columns => ["hostname","event_id"]
}
mutate {
gsub => ["message", "hostname=", " "]
} But, this will mess every words 'h' 'o' 's' and so on with other parsed messages and I don't think its the better way. Please suggest me the way.

The output I want is:
hostname => "test_machine"
event_id => "1145"

default type "default" to "_doc"

Can I update the default type from default to _doc in this Github repo as told in the lecture while I am doing the course?

The address is invalid error for orders-bulk.json

I encountered an 'Invalid address' error while attempting to access the resources file in the 111. Introduction to Aggregations lecture. Upon further investigation, I noticed that the file is not located within the Aggregations folder, which could be the root cause of the issue.

Wrong Link to importing-data-with-curl.md

Hello,
in querying-nested-objects.md, the "Follow Instruction" link is wrong and gives a 404 page.

An Advice for you :)

See I am giving you advice for your benefit as a teacher..
I watched your course on ElasticSearch.

You say you will update the application and then you express your inability that of not doing it.It gives a bad impression on me as a student.
What you should do instead.
You should say in beginning of the course that you will be using this version and ask be to use that version via docker so i do not experience any incompatibility.

This is a pattern which popular teacher like Mosh Hamedani does when he taught his course on docker (https://codewithmosh.com/p/the-ultimate-docker-course). He knew things can change so he explicity asks me to use the same version.

Action Step you should take is:
Say explicitly I am will be using v7 of elastic search and make me install it via docker compose.
