 # 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. For more information about how RCF works, see [Random Cut Forests](https://pdfs.semanticscholar.org/8bba/52e9797f2e2cc9a823dbd12514d02f29c8b9.pdf?_ga=2.56302955.1913766445.1574109076-1059151610.1574109076).

 ## (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.

However, if you use the internal user database, you can use the REST API to [add them manually](../../security/access-control/api/#create-user).

 # Introduction to OpenSearch

 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.
+Unsurprisingly, people often use search engines like 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.

-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.

 # Asynchronous search security

 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/).

 * 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).

If the magnitude of the query vector doesn't change throughout the query, you can pass the magnitude of the query vector to improve performance, instead of calculating the magnitude every time for every filtered document:<br /> `float cosineSimilarity (float[] queryVector, doc['vector field'], float normQueryVector)` <br />In general, the range of cosine similarity is [-1, 1]. However, in the case of information retrieval, the cosine similarity of two documents ranges from 0 to 1 because the tf-idf statistic can't be negative. Therefore, the k-NN plugin adds 1.0 in order to always yield a positive cosine similarity score.

 ## Constraints
+
 1. If a document’s `knn_vector` field has different dimensions than the query, the function throws an `IllegalArgumentException`.
+
 2. If a vector field doesn't have a value, the function throws an <code>IllegalStateException</code>.
+
   You can avoid this situation by first checking if a document has a value in its field:
-```
-"source": "doc[params.field].size() == 0 ? 0 : 1 / (1 + l2Squared(params.query_value, doc[params.field]))",
-```
-Because scores can only be positive, this script ranks documents with vector fields higher than those without.

-   To improve search performance, you must keep the number of segments under control. Lucene's IndexSearcher searches over all of the segments in a shard to find the 'size' best results. However, because the complexity of search for the HNSW algorithm is logarithmic with respect to the number of vectors, searching over five graphs with 100 vectors each and then taking the top 'size' results from 5*k results will take longer than searching over one graph with 500 vectors and then taking the top size results from k results.

   Ideally, having one segment per shard provides the optimal performance with respect to search latency. You can configure an index to have multiple shards to avoid giant shards and achieve more parallelism.

@ -86,9 +87,9 @@ Take the following steps to improve search performance:

 Recall depends on multiple factors like number of vectors, number of dimensions, segments, and so on. Searching over a large number of small segments and aggregating the results leads to better recall than searching over a small number of large segments and aggregating results. The larger the graph, the more chances of losing recall if you're using smaller algorithm parameters. Choosing larger values for algorithm parameters should help solve this issue but sacrifices search latency and indexing time. That being said, it's important to understand your system's requirements for latency and accuracy, and then choose the number of segments you want your index to have based on experimentation.

-To configure recall, adjust the algorithm parameters of the HNSW algorithm exposed through index settings. Algorithm parameters that control recall are `m`, `ef_construction`, and `ef_search`. For more information about how algorithm parameters influence indexing and search recall, see [HNSW algorithm parameters](https://github.com/nmslib/hnswlib/blob/master/ALGO_PARAMS.md). Increasing these values can help recall and lead to better search results, but at the cost of higher memory utilization and increased indexing time.

 ## Approximate nearest neighbor versus score script

 The standard k-NN query and custom scoring option perform differently. Test with a representative set of documents to see if the search results and latencies match your expectations.

-Custom scoring works best if the initial filter reduces the number of documents to no more than 20,000. Increasing shard count can improve latency, but be sure to keep shard size within the [recommended guidelines](../../opensearch/#primary-and-replica-shards).
