# Fetch user suggestions
> Search for users by a query string
export const SpaceReputationParams = ({variant = "context", field = "path"}) => {
const isUser = variant === "user";
return <>
Opt-in. Adds a spaceReputation number to each returned user,
scoped to a single space. Requires the reputation bundle.
The reputation total is always present regardless;{" "}
spaceReputation is purely additive and only appears when you
pass this object. This object is the primary form — it
replaces the deprecated flat props below. See the{" "}
Reputation data model for the
full contract.
{isUser ?
Which bucket to read. A space <uuid> reads that
space's bucket; "none" reads the
project-general (space-less) bucket.{" "}
"context" is rejected (400) on this
endpoint — there is no space context to derive. The empty string
and the legacy general / null aliases are
also rejected. Missing buckets read as 0.
:
Which bucket to read. One of: a space <uuid>{" "}
(that space's bucket), "none" (the
project-general, space-less bucket), or{" "}
"context" (the space derived from the
request context — resolved per-row on lists, or the single space on
member/team/conversation surfaces). The empty string and the legacy{" "}
general / null aliases are rejected (400).
Missing buckets read as 0.
}
Only honored when spaceId is an explicit space <uuid>.
When true, spaceReputation is the{" "}
subtree sum — the named space plus all of its
descendant spaces (the root space's own bucket included). Ignored for{" "}
"none"; not allowed with "context".
{isUser ? Deprecated — use the spaceReputation{" "}
object instead. The flat form of spaceReputation.spaceId.
Still accepted (the object wins if both are passed); removal is a later
major version. Accepts a space <uuid> or "none" only —{" "}
"context" is rejected (400) on this endpoint.

## Overview
`useFetchUserSuggestions` returns a function that searches for users by a query string. This is the underlying hook used by [`useUserMentions`](/v8/hooks/users/use-user-mentions) for `@mention` autocomplete, but it can also be used for any user search or autocomplete UI.
This hook uses an authenticated request. The user must be signed in.
## Usage Example
```tsx theme={null}
import { useFetchUserSuggestions } from "@sublay/react-js";
import { useState } from "react";
function UserSearch() {
const fetchSuggestions = useFetchUserSuggestions();
const [results, setResults] = useState([]);
const handleSearch = async (query: string) => {
const users = await fetchSuggestions({ query });
setResults(users);
};
return (
handleSearch(e.target.value)}
placeholder="Search users..."
/>
);
}
```
## Parameters
The hook returns a function. That function accepts:
The search string. Matched against usernames and names.
## Returns
An array of matching users' public profiles. When `spaceReputation` is requested, each carries an added `spaceReputation` number. See [User data model](/v8/data-models/user) and [Reputation](/v8/data-models/reputation).
