 # OpenSearch CLI

 The OpenSearch CLI command line interface (opensearch-cli) lets you manage your OpenSearch cluster from the command line and automate tasks.

-Currently, opensearch-cli supports the [Anomaly Detection](../ad/) and [k-NN](../knn/) plugins, along with arbitrary REST API paths. Among other things, you can use opensearch-cli to create and delete detectors, start and stop them, and check k-NN statistics.
+Currently, opensearch-cli supports the [Anomaly Detection]({{site.url}}{{site.baseurl}}/monitoring-plugins/ad/) and [k-NN]({{site.url}}{{site.baseurl}}/search-plugins/knn/) plugins, along with arbitrary REST API paths. Among other things, you can use opensearch-cli to create and delete detectors, start and stop them, and check k-NN statistics.

 Profiles let you easily access different clusters or sign requests with different credentials. opensearch-cli supports unauthenticated requests, HTTP basic signing, and IAM signing for Amazon Web Services.

 Anomaly detection  automatically detects anomalies in your OpenSearch data in near real-time using the Random Cut Forest (RCF) algorithm. RCF is an unsupervised machine learning algorithm that models a sketch of your incoming data stream to compute an `anomaly grade` and `confidence score` value for each incoming data point. These values are used to differentiate an anomaly from normal variations.

If you use an extraction query to define your monitor, use the **Run** button to ensure that the response includes the fields you need.


 ## (Advanced) Limit access by backend role

 Out of the box, the alerting plugin has no concept of ownership. For example, if you have the `cluster:admin/opensearch/alerting/monitor/write` permission, you can edit *all* monitors, regardless of whether you created them. If a small number of trusted users manage your monitors and destinations, this lack of ownership generally isn't a problem. A larger organization might need to segment access by backend role.

-First, make sure that your users have the appropriate [backend roles](../../security/access-control/). Backend roles usually come from an [LDAP server](../../security/configuration/ldap/) or [SAML provider](../../security/configuration/saml/). However, if you use the internal user database, you can use the REST API to [add them manually](../../security/access-control/api/#create-user).

 OpenSearch is a distributed search and analytics engine based on [Apache Lucene](https://lucene.apache.org/). After adding your data to OpenSearch, you can perform full-text searches on it with all of the features you might expect: search by field, search multiple indices, boost fields, rank results by score, sort results by field, and aggregate results.

-Unsurprisingly, people often use OpenSearch as the backend for a search application---think [Wikipedia](https://en.wikipedia.org/wiki/Wikipedia:FAQ/Technical#What_software_is_used_to_run_Wikipedia?) or an online store. It offers excellent performance and can scale up and down as the needs of the application grow or shrink.

It offers excellent performance and can scale up and down as the needs of the application grow or shrink.

-An equally popular, but less obvious use case is log analytics, in which you take the logs from an application, feed them into OpenSearch, and use the rich search and visualization functionality to identify issues. For example, a malfunctioning web server might throw a 500 error 0.5% of the time, which can be hard to notice unless you have a real-time graph of all HTTP status codes that the server has thrown in the past four hours. You can use [OpenSearch Dashboards](../opensearch-dashboards/) to build these sorts of visualizations from data in OpenSearch.

 You can run OpenSearch locally on a laptop---its system requirements are minimal---but you can also scale a single cluster to hundreds of powerful machines in a data center.

-In a single node cluster, such as a laptop, one machine has to do everything: manage the state of the cluster, index and search data, and perform any preprocessing of data prior to indexing it. As a cluster grows, however, you can subdivide responsibilities. Nodes with fast disks and plenty of RAM might be great at indexing and searching data, whereas a node with plenty of CPU power and a tiny disk could manage cluster state.

 You can use the security plugin with asynchronous searches to limit non-admin users to specific actions. For example, you might want some users to only be able to submit or delete asynchronous searches, while you might want others to only view the results.

-All asynchronous search indices are protected as system indices. Only a super admin user or an admin user with a Transport Layer Security (TLS) certificate can access system indices. For more information, see [System indices](../../security/configuration/system-indices/).

 If these roles don’t meet your needs, mix and match individual asynchronous search permissions to suit your use case. Each action corresponds to an operation in the REST API.

 ### Best practices
@ -148,6 +149,6 @@ For the warmup operation to function properly, follow these best practices:

 * Don't run merge operations on indices that you want to warm up. During merge, the k-NN plugin creates new segments, and old segments are sometimes deleted. For example, you could encounter a situation in which the warmup API operation loads graphs A and B into native memory, but segment C is created from segments A and B being merged. The graphs for A and B would no longer be in memory, and graph C would also not be in memory. In this case, the initial penalty for loading graph C is still present.

-* Confirm that all graphs you want to warm up can fit into native memory.

 # Approximate k-NN search

 The approximate k-NN method uses [nmslib's](https://github.com/nmslib/nmslib/) implementation of the Hierarchical Navigable Small World (HNSW) algorithm to power k-NN search. In this case, approximate means that for a given search, the neighbors returned are an estimate of the true k-nearest neighbors. Of the three methods, this method offers the best search scalability for large data sets. Generally speaking, once the data set gets into the hundreds of thousands of vectors, this approach is preferred.

-The k-NN plugin builds an HNSW graph of the vectors for each "knn-vector field"/ "Lucene segment" pair during indexing that can be used to efficiently find the k-nearest neighbors to a query vector during search. To learn more about Lucene segments, please refer to [Apache Lucene's documentation](https://lucene.apache.org/core/8_7_0/core/org/apache/lucene/codecs/lucene87/package-summary.html#package.description). These graphs are loaded into native memory during search and managed by a cache. To learn more about pre-loading graphs into memory, refer to the [warmup API](../api#warmup). Additionally, you can see what graphs are already loaded in memory, which you can learn more about in the [stats API section](../api#stats).

 # Exact k-NN with scoring script
+
 The k-NN plugin implements the OpenSearch score script plugin that you can use to find the exact k-nearest neighbors to a given query point. Using the k-NN score script, you can apply a filter on an index before executing the nearest neighbor search. This is useful for dynamic search cases where the index body may vary based on other conditions.

-Because the score script approach executes a brute force search, it doesn't scale as well as the [approximate approach](../approximate-knn). In some cases, it might be better to think about refactoring your workflow or index structure to use the approximate approach instead of the score script approach.
