Methods and systems for starting a node without a default password are provided. Exemplary methods include: creating a node responsive to indicia received from a user; checking for an existing keystore in the node; when no existing keystore is in the node: generating a seed password for a predefined user of the node; non-persistently providing the seed password to the user; creating an encrypted keystore in the node; and storing the seed password in the encrypted keystore; and allowing access to the node using the built-in user and seed password.

Default password removal

Methods and systems for searching a frozen index are provided. Exemplary methods include: a method may comprise: receiving an initial search and a subsequent search; loading the initial search and the subsequent search into a throttled thread pool, the throttled thread pool including; getting the initial search from the throttled thread pool; storing a first shard from a mass storage in a memory in response to the initial search; performing the initial search on the first shard; providing first top search result scores from the initial search; and removing the first shard from the memory when the initial search is completed.

Frozen indices

Methods and systems for shard splitting are provided. Exemplary methods include: marking a source index as read only, the source index comprising a source shard, the source shard comprising a source reference; creating a target index, the target index comprising target shards, each target shard of the target shards comprising a target reference of target references; copying the source reference, the copying producing the target references; hashing identifiers in the source reference, each identifier being associated with a document of a plurality of documents of the source shard, the hashing assigning each document of the plurality of documents to a target shard of the target shards, the plurality of documents being stored in a file associated with the source reference; hard linking the file into the target references; marking the target index as read-write; and deleting the source index.

Shard splitting

Asynchronous search of electronic assets via a distributed search engine is disclosed herein. An example method includes receiving a request from a user, the request including a query and a query time parameter, the query time parameter defining a time that the user will wait for results to be completed synchronously, determining that the query is incomplete and that the time has been exceeded, issuing the query a unique query identifier, and asynchronously adding results to an index based on the unique query identifier.
