PREPARE STATEMENT

The documentation on PREPARE STATEMENT page https://developer.couchbase.com/documentation/server/current/n1ql/n1ql-language-reference/prepare.html describes extensively how to use prepare statement using REST API   

I was using the Query workbench to test the PREPARE statement functionality as follow:

prepare mq1 as SELECT * from `travel-sample` limit 2;

I then not sure how I will invoke the named prepared statement mq1, so I tried

execute mq1;

that works.

It would be useful to reference the location where we document Using Prepared Statement in Workbench or cbq. 

More complicated scenario:

prepare mq2 as SELECT * from `travel-sample` where type = $t limit 2;

I then tried to figure out how to execute mq2 with bind variable value for $t, I could not guess the right syntax.
