Improved instructions for getting search indices
Improved instructions for getting search indices

I had no indices at all, which meant that the index data was inserted
correctly, but there were no index settings. This meant that a search from
Rummager would fail because the expected ``query_default`` query analyzer
didn't exist.

Secondly, it appeared to create new indices, but they were unaliased, so they
were in a state inconsistent with everything else.
