Retrieve the list of posts for a particular forum From this question, I know how to retrieve a list of forum posts (forum topics?) from drupal.  

curl -i -X GET  \
 -H Cookie:SESSe6a353351df0bcafe98787beef=B0YAHD3-reWwwW-kzhqw6A-SgeShSYUAAQQjh \
 'http://myserver/rest/node?parameters\[type\]=forum'


Now, I'd like to limit the list of forum posts to those belonging to a particular forum.  How do I filter the result by forum? I know the forum tid. I just don't know how to format the query. 

This doesn't cut it: 

curl -i -X GET  \
 -H Cookie:SESSe6a353351df0bcafe98787beef=B0YAHD3-reWwwW-kzhqw6A-SgeShSYUAAQQjh \
 'http://myserver/rest/node?parameters\[type\]=forum&amp;tid=4'


The above returns all forum posts. This also does not work: 

curl -i -X GET  \
 -H Cookie:SESSe6a353351df0bcafe98787beef=B0YAHD3-reWwwW-kzhqw6A-SgeShSYUAAQQjh \
 'http://myserver/rest/node?parameters\[type\]=forum&amp;parameters\[tid\]=4'


It gives me: 


  "Invalid query provided, double check that the fields and parameters you defined are correct and exist. SQLSTATE[42S22]: Column not found: 1054 Unknown column 'tid' in 'where clause'"


I get the same error if I try to reference parameters\[taxonomy_forums\]

Any help?
To get all posts (forum topics) for a particular forum with id=4: 

curl -i -X POST \
  -H Cookie:SESSe6a3baadbeef=ovQpO6aYeehaw_3W4onya22i9bonusQW \
  -H X-CSRF-Token:v6j7r9RactujA872hSHSKW-mYYWAA \
  -H Accept:application/json \
  -H Content-Type:application/json \
  http://myserver/rest/taxonomy_term/selectNodes \
  -d '{"tid":4}'


To find the mapping between forums and tids, refer to this answer. 

I don't know how to do a parameterized query (GET) to retrieve forum topics. As far as I can tell you need to use POST, as described here.
