How to add a new column to the Lucene index?

[maylingge]

Hi experts,
It's just a question. Might be a silly one.
I am not sure how to update a Lucene index. It seems I need to drop the index and create it again when I need to add a new column to the index.

For example, if I have index define as following:
CREATE CUSTOM INDEX tweets_index ON tweets ()
USING 'com.stratio.cassandra.lucene.Index'
WITH OPTIONS = {
'refresh_seconds': '1',
'schema': '{
fields: {
id: {type: "integer"},
user: {type: "string"},

  }

}'
};

And now I have another column to add to the index as following:
body: {type: "text", analyzer: "english"}

Should I drop the old index and create a new one as folowing:
CREATE CUSTOM INDEX tweets_index ON tweets ()
USING 'com.stratio.cassandra.lucene.Index'
WITH OPTIONS = {
'refresh_seconds': '1',
'schema': '{
fields: {
id: {type: "integer"},
user: {type: "string"},
body: {type: "text", analyzer: "english"},
}
}'
};

Thanks!
