ES 2.2 Allocated memory Elasticsearch

[nanto]

Elasticsearch version 5.6

Hello, where do I set the allocated memory for Elasticsearch.
In the control panel I get 1.9 MB.

This is entered in elasticsearch/config/jvm.options:

# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space

-Xms2g
-Xmx2g

I guess that's wrong then ...
Would be grateful for a hint where I have to specify that.

I may get this wrong too.
The problem is that the search results are bad at the moment.
Not all posts are found.

But I also recently had a server failure.
I'll have the search index rebuilt.
Perhaps the problem will then be resolved.
