Does aliasing require reindexing?

Elastic Stack Elasticsearch
1

hi,
i just wanted to confirm something.. if i already have a bunch of data for
different users in an index with 5 shards and now i want to create an alias
for each user with a filter and routing parameter associated with it, then
i have to reindex the data for that user using either the new index name or
routing parameter, right? otherwise, data that is not in the routed shard
will never come up in searches against that alias index.

thanks
