62   -By default, Tire creates an index on 5 shards - even in development. With a low number of documents, you will get inconsistent relevance scores by default. You can [read more about it here](http://www.elasticsearch.org/blog/understanding-query-then-fetch-vs-dfs-query-then-fetch/). To fix this, set the search type to `dfs_query_and_fetch`. Alternatively, you can just use one shard `settings: {number_of_shards: 1}`.
  64 +Elasticsearch was built to be distributed. However, with a low number of documents, the default settings can give us incorrect results. You can [read more about it here](http://www.elasticsearch.org/blog/understanding-query-then-fetch-vs-dfs-query-then-fetch/). To fix this, set the search type to `dfs_query_and_fetch`. Alternatively, you can just use one shard with `settings: {number_of_shards: 1}`.
