Updating Index Schema

Depending on how your index is defined (JSON or Hash) you can use the AlterHashSchema(Async) or AlterJsonSchema(Async) methods to expand the index's schema definition.

Previously we had the method AlterSchema(Async but I decided to deprecate that in favor of the more specific methods. The reason for separate methods is each type of index uses a different kind of field builder.

Let's take a look at an example where I'm adding a TEXT field and a GEO field to an existing hash based index.

await _db.AlterHashSchemaAsync("existing_index", 
    fb => fb.Text("NewTextField", noindex: true), 
    fb => fb.Numeric("NewNumericField", sortable: true)
);

The following is an example of using AlterJsonSchemaAsync...

await _db.AlterJsonSchemaAsync("existing_json_index",
  fb => fb.Text("$.newTextField, "NewTextField", noindex: true),
  fb => fb.Numeric("$.newNumericField", sortable: true)
);
