Index Information API

The simplest form of INFO gets information about an index:

INFO /twitter/tweet/

INFO /twitter/tweet/1 is not the same as INFO /twitter/tweet/1/, the former will retrieve information about document 1 inside index /twitter/tweet/ and the later will retrieve information about thewhole index /twitter/tweet/1/. Trailing slashes are important.

The response will include the following information about the index:

• uuid - UUID of the xapian database.
• revision - Internal document ID (shown only for shard databases).
• doc_count - Documents count.
• last_id - Last used ID.
• doc_del - Documents deleted.
• av_length - Average length of the documents.
• doc_len_lower - Statistics about documents length.
• doc_len_upper - Statistics about documents length.
• has_positions - Boolean indicating if the database has positions stored.
• shards - List of shard databases.
