/api/v1/suggest

Auto-suggest / autocomplete. Given the user's current input, returns candidate completions either as token frequencies (tokens) or as per-field value matches (fields), plus optionally the full linked-object descriptors for picker UIs (linked_objects). Backed by the search index — the same language settings apply.

Read-only: the request runs in a read transaction; nothing is written. The handler enforces no specific right and no login — an anonymous request is accepted; results are scoped to whatever the session is allowed to see via the per-user best-mask filter.

GET /suggest — Auto-suggest with the request encoded in the URL.

Auto-suggest with the request encoded in the URL.

get

Identical semantics to POST /suggest; the JSON request is passed verbatim as the BODY query parameter. Useful for front ends that prefer not to send a GET body.

The query parameter name is BODY (uppercase) — the handler reads r.URL.Query().Get("BODY") case-sensitively, so a lowercase body=... is not picked up; an absent or empty BODY then fails JSON parsing and returns a 400.

JSON-encoded SuggestRequest. See the request schema on POST /suggest for the field set.

Responses

200

Suggestion envelope.

application/json

Auto-suggest response — returned by GET /api/v1/suggest and POST /api/v1/suggest. Carries diagnostic timing info plus a suggestions envelope with the three optional result sets the request opted into.

es_timeinteger · int64Optional

Time the search index spent on the request, in milliseconds. Excludes fylr-side serialisation overhead.

timed_outbooleanOptional

True if the request reached the per-request timeout. Partial results may still be present in suggestions.

400

Malformed request — invalid JSON in BODY, an objecttype in objecttypes or linked_objecttypes that does not exist, an unresolvable entry in fields, or an unknown tokens_mode (the latter only rejects when token suggestions run, i.e. unless tokens is false). All return ServerGeneric / 400; the handler emits no other status.

Authorizations

BearerAuthAccessTokenQueryFylrAuthHeader

AuthorizationstringRequired

Access token in the Authorization header: Authorization: Bearer <token>.

Body

application/json

Auto-suggest request — accepted as the JSON request body of POST /api/v1/suggest, and as the value of the BODY query parameter on GET /api/v1/suggest. Drives token and / or field completion through the search index.

Each result kind is opted into independently: token suggestions (tokens, on by default unless tokens is false), per-field value matches (fields_suggest: true, which also needs a non-empty fields), and linked-object descriptors (a non-null linked_objecttypes).

querystringOptional

The user's current input. Optional; defaults to the empty string. Tokenised (whitespace-split) unless tokens_dont_split_query is set. The last token is treated as the partial term to complete.

tokens_dont_split_querybooleanOptional

If true, the query is sent verbatim — the engine does not split it on whitespace. Useful when the input is a multi-word phrase that should match as a single token.

Default: false

tokensboolean · nullableOptional

If true, null, or omitted, return token completions in suggestions.tokens. Set to false to suppress them. Independent of fields_suggest.

fieldsstring[]Optional

Field paths whose values should be considered as completion candidates. Each entry is a fully-qualified field name (e.g. picture.title, _tags.tag.name). Must be non-empty to get any per-field suggestions: combining fields_suggest: true with an empty fields yields no suggestions.fields (it is a silent no-op, not an error).

fields_suggestbooleanOptional

If true, also return per-field completions in suggestions.fields — one entry per matching value, with the list of system-object ids that hold it.

Default: false

objecttypesstring[]Optional

Restrict suggestions to objects of these objecttypes. Empty / omitted means no restriction.

pool_idsinteger · int64[]Optional

Restrict suggestions to objects in exactly these pools — there is no automatic sub-pool inclusion. Empty / omitted means no restriction.

languagesstring[]Optional

Restrict token / field matching to these language-tagged sub-fields (e.g. de-DE, en-US). Empty means consider all languages enabled on the instance.

linked_objecttypesstring[] · nullableOptional

If set, the engine also returns linked_objects — full ObjectApi entries of the named objecttypes that match the query. Useful for autocomplete pickers that need to show the target object inline.

analyze_wildcardsbooleanOptional

If true, the query string is interpreted as a wildcard pattern (* and ?) rather than a prefix. Applies to token suggestions only; the field and linked-object searches ignore it.

Default: false

tokens_modestring · enumOptional

Token-matching mode. One of:

• `` (empty) / ngram — substring match (default).
• edgengram — prefix match.
• exact — exact-term match.

Any other value is rejected with a 400.

Possible values:

timeoutintegerOptional

Per-request timeout in milliseconds passed through to the search index. Zero / omitted uses the indexer's default.

limitintegerOptional

Maximum number of suggestions to return (per kind). Defaults to 10 when unset or zero.

Default: 10
