OpenSearch terms
This is how we use our terms, but we’re always open to hearing your suggestions.
A
ad hoc
Avoid. Use one-time instead.
affect
Affect as a noun refers to emotion as expressed in face or body language. Affect as a verb means to influence. Do not confuse with effect.
AI/ML
On first mention, use artificial intelligence and machine learning (AI/ML).
Alerting
A plugin that notifies you when data from one or more OpenSearch indexes meets certain conditions.
allow
Use allow when the user must have security permissions in order to complete the task.
Avoid using allow to refer to making something possible for the user. Instead, rewrite to focus on what’s important from the user’s point of view.
allow list
Use to describe a list of items that are allowed (not blocked). Do not use as a verb. Do not use whitelist.
Amazon OpenSearch Service
Amazon OpenSearch Service is a managed service that makes it easy to deploy, operate, and scale OpenSearch clusters in the AWS Cloud. Amazon OpenSearch Service is the successor to Amazon Elasticsearch Service (Amazon ES) and supports OpenSearch and legacy Elasticsearch OSS (up to 7.10, the final open-source version of the software).
Anomaly Detection
A plugin that automatically detects anomalies in your OpenSearch data in near real time.
API
application programming interface
API operation
Use instead of action, method, or function.
OpenSearch style:
- Use the CopySnapshot operation to...
- The following API operations…
Not OpenSearch style
- Use the CopySnapshot action to...
- Use the CopySnapshot method to...
- Use the CopySnapshot function to...
app or application
Use app for mobile software, application for all other uses.
appear, display, and open
Messages and pop-up boxes appear. Windows, pages, and applications open. The verb display requires a definite object. For example: The system displays the error message.
application server
Do not abbreviate as app server.
as well as
Avoid. Replace with in addition to or and as appropriate.
Asynchronous Search
A plugin that lets the user send search requests in the background so that the results can be used later.
auto scaling
Lower case scaling, auto scaling, and automatic scaling (but not autoscaling) are the preferred descriptive terms when generically describing auto scaling functionality.
Do not use hyphenated auto-scaling as a compound modifier. Instead, use scaling (for example, scaling policy), or scalable (for example, scalable target or scalable, load-balanced environment).
B
below
Use only for physical space or screen descriptions, such as “the outlet below the vent,” or “the button below the bar pane.”
For orientation within a document, use following or later.
big data
Boolean
Avoid using the name of a Boolean value at the beginning of a sentence or sentence fragment. In general, capitalize the word Boolean. For specific programming languages, follow the usage in that language.
OpenSearch style:
- You can use the Boolean functions with Boolean expressions or integer expressions.
- IsTruncated(): A Boolean value that specifies whether the resolved target list is truncated.
bottom
Use only as a general screen reference, such as “scroll to the bottom of the page.” Don’t use for window, page, or pane references to features or controls. Rather, use lower instead. For example, you can use the following wording: “Choose the button on the lower left.”
browse
Use when referring to scanning information or browsing the web. Don’t use when describing how to navigate to a particular item on our site or a computer. Instead, use see or navigate to.

console
A tool inside OpenSearch Dashboards used to interact with the OpenSearch REST API.
Cross-Cluster Replication
A plugin that replicates indexes, mappings, and metadata from one OpenSearch cluster to another. Follows an active-passive model where the follower index pulls data from a leader index.
cyber
Except when dictated by open standards, use as a prefix in a closed compound: don’t use spaces or hyphens between cyber and the rest of the word.
D
data
Use data is, not data are. Don’t use datas. Use pieces of data or equivalent to describe individual items within a set of data.
data center
dataset
data store, datastore
Two words when used generically, but one word when referring to the VMware product.
data type
dates
Use one of the following date formats:
- When a human-readable date format is preferred, spell out the date using the Month D, YYYY format (for example, October 1, 2022). Do not use an ordinal number for the day (use 1, not 1st). If the context is clear, you can omit the year on subsequent mention. If the specific day isn’t known, use the Month YYYY format (for example, October 2022).
- When a numeric, lexicographically sortable date is required, use the YYYY-MM-DD format (for example, 2022-10-01). Make sure to add a zero (0) in front of a single-digit month and day. This is the ISO 8601 standard date format. Make sure also that you use a hyphen (-) and avoid omitting the year. Doing so avoids the ambiguity that’s caused by the common, locally used formats of MM/DD and DD/MM.
deny list
Use to describe a list of items that aren’t allowed (blocked). Do not use blacklist.
double-click
Always hyphenated. Don’t use double click.
dropdown list

e.g.
Avoid. Use for example or such as instead.
Elastic IP address
Use as a singular noun or adjective to refer to the collective concept, and use message or mail for individual items. Use send email as the verb form. Don’t use the plural form because it’s a collective noun.
enable
Use turn on or activate instead of enable to support bias-free documentation, when possible. Otherwise, use enable to describe making a feature or command available.
enter
In general, use in preference to type when a user adds text or other input (such as numbers or symbols).
etc., et cetera
Do not use.
Generally speaking, etc. and its equivalents (such as and more or and so on) aren’t necessary.
F
fail over (v.), failover (n.)

frontend (n., adj.)
Use frontend as an adjective and a noun. Do not use front end or front-end. Do not make frontend possessive except as part of a compound noun, such as frontend system.
H

hard disk drive (HDD)
high availability (HA)
high performance computing (HPC)
hostname
I
i.e.
Do not use. Use that is or specifically instead.
in, on

leverage
Replace with use.
lifecycle
One word in reference to software.
like (prep.)
OK to use to call out something for comparison.
As a general rule, if you can replace like with similar to, it’s OK to use like. But, if you can replace like with such as, use such as.
locate in, on
Located in (a folder, directory, path), located on a disk drive or instance.
log in (v.), login (adj., n.)
Use with technologies with interfaces that use this verb. Also note that you log in to an instance, not log into. Also use log out and logout.

OpenSearch
OpenSearch is a community-driven, open-source search and analytics suite derived from Apache 2.0 licensed Elasticsearch 7.10.2 and Kibana 7.10.2. It consists of a search engine daemon, OpenSearch, and a visualization and user interface, OpenSearch Dashboards.
OpenSearch Dashboards
The default visualization tool for data in OpenSearch. On first appearance, use the full name. “Dashboards” may be used on subsequent appearances as long as it is defined on first appearance: “OpenSearch Dashboards (Dashboards).”
open source (n.), open-source (adj.)
Use open source as a noun (for example, “The code used throughout this tutorial is open source and can be freely modified”). Use open-source as an adjective (open-source software).
operating system
When referencing operating systems in documentation, follow these guidelines:
- In general, if your docs or procedures apply to both Linux and macOS, you can also include Unix.
- Unix and UNIX aren’t the same. UNIX is a trademarked name that’s owned by The Open Group. In most cases, you should use Unix.
- When referring to the Mac operating system, use macOS. Don’t say Mac, Mac OS, or OS X.
- When referring to Windows, it’s not necessary to prefix with Microsoft.
- If you need to reference multiple Unix-like operating systems, you should separate by commas and use the following order: Linux, macOS, or Unix.

per
- Do not use to mean according to (for example, per the agreement).
- OK to use in meaning of to, in, for, or by each (one per account) where space is limited and in set terms and phrases, such as any of the following:
- queries per second (QPS)
- bits per second (bps)
- megabytes per second (MBps)
- Consider writing around per elsewhere. Per can sound stuffy and confusing to some global users.
percent

R
real time (n.) real-time (adj.)
Use with caution; this term can imply a degree of responsiveness or speed that may not be true. When needed, use real time as a noun (for example “The request is sent in real time”). Use real-time as an adjective (“A real-time feed is displayed...”).
replica shard
Copy of a primary shard. Helps improve performance when using indexes across multiple nodes.
repo

solid state drive (SSD)
standalone
start, launch
You start an application but launch an instance, environment, or cluster.

while, although, whereas
Only use while to mean “during an interval of time.” Don’t use it to mean although because it is often ambiguous. Whereas is a better alternative to although in many cases, but it can sound overly formal.
wish, want, desire, need
Wish and desire are indirect and nuanced versions of want. Don’t use them. Be direct.
