How do you add nested fields to a text index in MongoDB?

Question

I'm having trouble adding nested fields to a text index in MongoDB.

The code below adds string fields at the top level to the text index correctly. The two nested fields "contentright" and "contentfooterhead" that I am trying to add are added but do not index correctly.

enter image description here

var keys = {"name", "subject", "contentright", "contentfooterhead"};

var indexKeys = new IndexKeysBuilder();
indexKeys.Text(keys);

var options = new IndexOptionsBuilder();
options.SetName("testIndex");
options.SetBackground(true);

collection.CreateIndex(indexKeys, options);

This is what my text index looks like after the code is run:

enter image description here

If I run

indexKeys.TextAll();

which is equivalent to an index of

"$**": "text"

all the fields are indexed fine, but I don't want to add them all.

Use dot notation. The paths to your nested fields are Con.contentright and Con.contentfooterhead.
