define the number of shards you want. Each shard itself has the full functionality of the index and can be stored in any node in the cluster. Sharding is important for two main reasons: It allows you to split/scale your content horizontally It allows you to distribute operations in parallel to shards on multiple nodes, which can improve performance or throughput. The mechanism for fragmentation distribution, and how its documentation is

The blogs and tags above are a good example: the left is the raw data, and a blog can have multiple tags. Right by inverted index makes each tag point to the blog that owns it. This way, when searching for tags, the left side can only iterate through the lookup, and the right side can directly find all the corresponding blogs. ensure the relevance of the r
