upload stopwords and synonyms to Elasticsearch cloud server - elasticsearch

Question

I have deployed my Elasticsearch server to the cloud: cloud.elastic.co
I have seen stopwords and synonyms documentation, which explain stopwords.txt/synonyms.txt files could be copied under config folder... but how can I do this on a cloud server?
I know I can pass the stopwords in an array, but using a file, it would be easier to update them:
Updating stopwords is easier if you specify them in a file with the
stopwords_path parameter. You can just update the file (on every node
in the cluster) and then force the analyzers to be re-created by
either of these actions

Answer 1

You have to use Custom Plugins section to manage any custom plugins, scripts or dictionaries (stopwords, synonymns, etc.)
Steps:
Create a zip file with the following directory structure:
.
|__ dictionaries
|__ stopwords.txt
Login to elastic cloud and go to Custom Plugins section
Click on Add Plugin
Fill in the relevant details and for the section Plugin Type select A bundle containing a dictionary or script
Click on Create Plugin
Go back to the Custom plugins page and click on the new plugin you just added.
Scroll to the bottom and upload the zip file created in first step.
Now you have to update your cluster so that its available to all the nodes. To do this follow the steps below:
Click on Deployment
Select your cluster/deployment form the page
On the menu in the left click on Edit.
Scroll to the section Elasticsearch plugins and settings on the
page. Click on Manage plugins and settings.
From the expanded list select your bundle (located under Custom
Plugins section in the expanded list).
On the bottom of the page click on Save Changes
Wait for the update activity to complete. Once completed you can now use stopwords.txt as below:
"stopwords_path": "stopwords.txt"
Here is the complete elastic cloud documentation.
Documentation page for adding plugin/script/dictionary is here.
