# Search HTTP API
|
|
|
|
## Prefix Searching
|
|
|
|
The `/search` endpoint returns matches for a given prefix and context, where a
|
|
context can be jobs, allocations, evaluations, nodes, deployments, plugins,
|
|
namespaces, or volumes. When using Nomad Enterprise, the allowed contexts
|
|
include quotas. Additionally, a prefix can be searched for within every
|
|
context.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | ------------ | ------------------ |
|
|
| `POST` | `/v1/search` | `application/json` |
|
|
|
|
The table below shows this endpoint's support for
|
|
[blocking queries](/nomad/api-docs#blocking-queries) and
|
|
[required ACLs](/nomad/api-docs#acls).
|
|
|
|
| Blocking Queries | ACL Required |
|
|
| ---------------- | -------------------------------- |
|
|
| `NO` | `node:read, namespace:read-jobs` |
|
|
|
|
When ACLs are enabled, requests must have a token valid for `node:read` or
|
|
`namespace:read-jobs` roles. If the token is only valid for `node:read`, then
|
|
job related results will not be returned. If the token is only valid for
|
|
`namespace:read-jobs`, then node results will not be returned.
|
|
|
|
### Parameters
|
|
|
|
- `Prefix` `(string: <required>)` - Specifies the identifier against which
|
|
matches will be found. For example, if the given prefix were "a", potential
|
|
matches might be "abcd", or "aabb".
|
|
- `Context` `(string: <required>)` - Defines the scope in which a search for a
|
|
prefix operates. Contexts can be: "jobs", "evals", "allocs", "nodes",
|
|
"deployment", "plugins", "volumes" or "all", where "all" means every
|
|
context will be searched.
|
|
|
|
### Sample Payload (for all contexts)
|
|
|
|
```json
|
|
{
|
|
"Prefix": "abc",
|
|
"Context": "all"
|
|
}
|
|
```
|
|
|
|
### Sample Request
|
|
|
|
```shell-session
|
|
$ curl \
|
|
--request POST \
|
|
--data @payload.json \
|
|
https://localhost:4646/v1/search
|
|
```
|
|
|
|
### Sample Response
|
|
|
|

|
|
"allocs": null,
|
|
"deployment": null,
|
|
"evals": ["abc2fdc0-e1fd-2536-67d8-43af8ca798ac"],
|
|
"jobs": ["abcde"],
|
|
"nodes": null,

|
"volumes": null
|
|
},

}
|
|
}
|
|
```
|
|
|
|
#### Field Reference
|
|
|
|
- `Matches` - A map of contexts to matching arrays of identifiers.
|
|
|
|
- `Truncations` - Search results are capped at 20; if more matches were found for a particular context, it will be `true`.
|
|
|
|
### Sample Payload (for a specific context)
|
|
|
|
```json
|
|
{
|
|
"Prefix": "abc",
|
|
"Context": "evals"
|
|
}
|
|
```
|
|
|
|
### Sample Request
|
|
|
|
```shell-session
|
|
$ curl \
|
|
--request POST \
|
|
--data @payload.json \
|
|
https://localhost:4646/v1/search
|
|
```
|
|
|
|
### Sample Response
|
|
|
|
```json
|
|
{
|
|
"Matches": {
|
|
"evals": ["abc2fdc0-e1fd-2536-67d8-43af8ca798ac"]
|
|
},
|
|
"Truncations": {
|
|
"evals": "false"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Fuzzy Searching
|
|
|
|
The `/search/fuzzy` endpoint returns partial substring matches for a given search
|
|
term and context, where a context can be jobs, allocations, nodes, plugins, or namespaces.
|
|
Additionally, fuzzy searching can be done across all contexts. For better control
|
|
over the performance implications of fuzzy searching on Nomad servers, aspects of
|
|
fuzzy searching can be tuned through the <code>[search]</code> block in Nomad agent config.
|
|
|
|
Fuzzy search results are ordered starting with closest matching terms. Items of
|
|
a name that exactly matches the search term are listed first.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | ------------------ | ------------------ |
|
|
| `POST` | `/v1/search/fuzzy` | `application/json` |
|
|
|
|
The table below shows this endpoint's support for
|
|
[blocking queries](/nomad/api-docs#blocking-queries) and
|
|
[required ACLs](/nomad/api-docs#acls).
|
|
|
|
| Blocking Queries | ACL Required |
|
|
| ---------------- | ----------------------------------------------------------- |
|
|
| `NO` | `node:read, namespace:read-jobs, namespace:csi-list-plugin` |
|
|
|
|
When ACLs are enabled, requests must have a token valid for `node:read`, `plugin:read` or
|
|
`namespace:read-jobs` roles. If the token is only valid for a portion of these
|
|
capabilities, then results will include results including only data readable with
|
|
the given token.
|
|
|
|
### Parameters
|
|
|
|
- `Text` `(string: <required>)` - Specifies the identifier against which
|
|
matches will be found. For example, if the given text were "py", potential
|
|
fuzzy matches might be "python", "spying", or "happy".
|
|
- `Context` `(string: <required>)` - Defines the scope in which a search for a
|
|
prefix operates. Contexts can be: "jobs", "allocs", "nodes", "plugins", or
|
|
"all", where "all" means every context will be searched. When "all" is selected,
|
|
additional prefix matches will be included for the "deployments", "evals", and
|
|
"volumes" types. When searching in the "jobs" context, results that fuzzy match
|
|
"groups", "services", "tasks", "images", "commands", and "classes" are also
|
|
included in the results.
|
|
|
|
### Scope
|
|
|
|
Fuzzy match results are accompanied with a `Scope` field which is used to uniquely
|
|
identify the matched object, in a way that the Nomad API can be queried again for
|
|
additional information. The data provided by scope varies depending on the type
|
|
of matched object, described below.
|
|
|
|
### Sample Payload (for jobs)
|
|
|
|
```json
|
|
{
|
|
"Text": "py",
|

"Context": "jobs"

|

|
```

```
|
|
|
|
### Prefix matching when fuzzy searching
|
|
|
|
If the search Context is `all` when fuzzy searching, the object types that are
|
|
identified only with UUIDs are also concurrently prefix-searched. Those types include
|
|
deployments, evals, volumes, and quotas (Enterprise).
|
|
|
|
### Sample Payload (prefix match)
|
|
|
|
```json
|
|
{
|
|
"Text":"cc",
|
|
"Context":"all"
|
|
}
