Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention will be further described:
[0022] Such as figure 1 , a p2p-based distributed real-time search engine, its cluster contains several nodes, each node contains more than one index, and each index is divided into more than one index fragments, the index fragments only contain the main shards or both a primary shard and more than one replica; as in figure 1 A cluster containing three nodes is shown, which contains node 1, node 2, and node 3, and node 1, node 2, and node 3 all contain two indexes, index 1 and index 2, where index 1 is divided into three Fragmentation: Fragment 1, Fragment 2, Fragment 3. At the same time, the number of copies of each fragment of Index 1 is 1, and Index 2 is divided into three fragments: Fragment 1', Fragment 2', Shard 3', and the number of copies of each shard of index 2 is 1; index 1 in node 1 contains shard 1 (copy), shard 3, and index 1 in node 2 contains shard 2, sha...
