Managing a search index

摘要

Concepts and technologies are described herein for managing a search index. In accordance with the concepts and technologies disclosed herein, a search index can be hosted by a number of search nodes. The search engine can be configured to determine if a search node is unavailable, and if so, if data stored at the unavailable search node is to be replaced. If data stored at the unavailable search node is to be replaced, the search engine can identify sources for data to be used to replace the data at the unavailable search node. The search engine can issue instructions to the sources and/or the unavailable search node to copy the data from the sources to the unavailable node and/or to replace the data at the unavailable node with the data from the sources. Portions of the data can be copied from each of the sources to the unavailable node.

1. A computer-implemented method for managing a search index, the computer-implemented method comprising performing computer-implemented operations for:
identifying, at a computer executing a search engine, a plurality of search nodes configured to host the search index; determining that an unavailable search node of the plurality of search nodes has been unavailable; determining if data stored at the unavailable search node is to be replaced; and in response to determining that the data at the unavailable search node is to be replaced,
identifying at least one source for the data, the at least one source comprising at least one of the plurality of the search nodes, andreplacing the data stored at the unavailable search node with data from the at least one source.
