The most useful Twitter user search by keyword checks two places at once: the bio where people describe themselves and the tweet history where they show what they care about. It then filters the matching accounts by activity, location and account age.
X's own search finds a name in seconds. Ask it for every recruiter who posts about hiring engineers, with dormant accounts removed and the result in a file, and it has neither the filter nor the export.
X's people results: type a keyword, open matching profiles individually, and copy handles by hand, with no account filters and no export. Circleboom: one keyword compared with bios and older posts on X, up to 5,000 accounts in a filterable table, all pulled via X's approved Enterprise API.

The sections below explain what each route finds and when to switch.
What is a Twitter user search by keyword?
A Twitter user search by keyword finds X accounts, not posts, whose bio or tweet history contains a word you choose. What comes back is people, ready to review, follow, sort into a List or export.
People run this kind of search to build something: a marketer's outreach list, a recruiter's shortlist, a founder's map of a new market, or a researcher's sample of accounts that discuss a topic. Each of them needs the list to be current, filtered and portable, not just found.
X covers part of this. Its search shows people results for a word, and X's help page on searching for people on X walks through that people search.
Where X's own search stops
What X leaves out is everything after the match. X's people results cannot be narrowed by how active an account is, how many followers it has, when it joined or where it lives, and there is no export.
It works for one name. It stalls on a list.
The gap hurts most once the list needs to go somewhere outside X. A recruiter cannot hand a hiring manager a screen of profile cards, and a marketer cannot import one into a CRM.
For a wider view of the account-search options, see search Twitter accounts. When you need many people rather than a single profile, a Twitter user search on X that reads bios and tweets removes the copying step.
Circleboom also runs tweet-level search. Its Twitter advanced search page covers finding posts rather than accounts, which is the right tool when you need the conversation itself.
How Circleboom's Deep X Account Search reads bios and past tweets
Deep X Account Search is Circleboom's account search for depth: it compares your keyword with X bios and with older tweets, and it can list up to 5,000 public profiles over 50 pages.
A bio hit finds people who call themselves by your term. A tweet hit finds people who wrote about it, whatever their bio says.
Data source matters for a people list. X's Enterprise customer directory includes Circleboom, so the profile data comes from X itself instead of a scraper that sees only what loads on a public page.
What each result row shows
Each account arrives with the signals you need to judge it:
| Column | What it tells you |
|---|---|
| Name | Display name, handle and stated location |
| Tweets and Joined | Total posts and account age in days |
| Following and Followers | Both counts, side by side |
| Follow Ratio | Follower count over following count, or N/A at zero following |
| Active & Inactive | Active, Moderate Active or Inactive, from current posting |
The activity label is computed from current posting, while the match may come from a years-old tweet. Read the two together before you decide.
Limits to know before you trust the list
A deep result is large, and its size can feel like completeness. It is not, for a few documented reasons:
- The search covers public profiles and public posts only, so protected profiles never appear.
- Deleted or edited tweets may be missing from the historical index.
- Bios, locations and follower counts are captured at search time, not on the day the matching post went out.
- The display tops out at 5,000 accounts per keyword.
A broad keyword can also take a while to process, since the scan covers far more history than a live search does.
None of these limits make the list wrong. They make it a starting point that needs a human read before anyone acts on it.
Search engines built for posts work differently, a contrast drawn in Twitter search engine. To test it on a niche you know, find X accounts by bio and tweets with a keyword the people would use about themselves.

Deep search or live search: which finds the X users you need?
Pick Deep X Account Search for coverage and Live X Account Search for timing. The deep search looks back through bios and older tweets.
The live search looks at what accounts are doing lately, so it returns a much shorter list, in the dozens where a deep run can reach thousands.
| Your situation | Search to run | What changes |
|---|---|---|
| Building an outreach or research list for a niche | Deep X Account Search | Larger list, includes long-standing voices and some quiet ones |
| Reaching people during a launch, event or trend | Live X Account Search | Smaller list of accounts posting on the topic now |
| Separating current voices from past ones | Both, then compare | Accounts in both results are active and on topic |
| Looking for high-reach accounts in a niche | Find Influencers | Results scoped by reach and engagement signals |
When reach matters more than fit, the page to find Twitter influencers is the narrower starting point.
What a deep result includes that a live one misses
The extra rows in a deep result come from time. They include accounts that were central to a topic during an earlier cycle and still carry weight in it, and specialists who post rarely but always on the subject.
Those rare posters are often the accounts worth contacting first, and a live search, anchored on this week's activity, cannot see them.
The same depth brings in accounts that moved on. Someone who tweeted about your keyword years ago may work in another field today, and the match alone cannot tell you that.
Use the comparison row when a campaign depends on replies. A large deep result can feel complete, but a match on old tweets says nothing about who is paying attention this month.
A match proves someone talked about the topic. It does not prove they still do.
Running the same keyword through both searches and keeping the overlap gives you a list that is on topic and awake.
How to run a Twitter user search by bio and tweets
A Twitter user search by bio and tweets takes four moves. Search wide with a people-shaped keyword, read the first page to judge it, filter before reviewing, and act only on the accounts you checked.
All four happen in Advanced X Search, Circleboom's search area for X.
- Launch Deep X Account Search with a keyword that describes the people, such as a job title or a tool name, rather than a broad topic.
- Read the result count and the first page before touching a filter, and rewrite the keyword if the rows look off target.
- Apply Filter Options, with Fake/Spam and Inactive on to drop spam-like and dormant profiles, then add location, join date or follower range if the brief calls for them.
- Check the boxes of accounts you have vetted, then follow them selectively, put them in a Twitter List, or download a CSV.
The order puts judgment where it is cheapest. Fixing a keyword on page one costs seconds, while fixing it after an export means rebuilding the file.
Save every keyword and filter set that produced a good list, so the next refresh starts from a proven query instead of a blank box.
Conditions combine, so each added filter narrows the same table. Following from the results stays gradual: follow actions are capped at 400 a day by Circleboom's pacing, and unfollows go out in blocks of 50 per 15 minutes, close to 800 daily.
How do you find one specific person on X?
To find one specific person on X, search their full name on X and look through the matching profiles. If you already know the username, a direct lookup is faster than any search.
Circleboom's Twitter account lookup page covers that direct check of a known profile.
Names fail in two common cases:
- You know what the person does but not what they are called.
- Their display name is a nickname or a brand, so a name search returns strangers.
In both cases, turn the person's role into the search term. Put the job or company term into Deep X Account Search, layer a second term into Find in Bio & Name, then type a city into Location.
That can leave a result small enough to check profile by profile.
Two more filters help with people who work for organizations. The Verification Status filter keeps verified or unverified accounts, and a minimum follower count sets aside tiny profiles that happen to share a common name.
If a name search keeps failing, read finding someone on Twitter.
If you do not use X at all and only need to look someone up, Twitter search without an account explains what you can still see while logged out.
Can you pull one account's followers instead of searching a keyword?
Yes. Circleboom's Followers / Following Search starts from a public X username and loads that account's follower list or following list as a filterable table ready to export.
It is the better route when your audience already gathers around one known account, such as a competitor, a community organizer or a publication.
The two searches answer different questions:
- A keyword search asks who talks about a topic anywhere on X.
- A followers search asks who chose to follow one specific account.
The followers route uses the same kind of account signals and filters, so the review habits carry over. Search, filter out spam and dormant accounts, then list, follow or export what remains.
When a followers search beats a keyword search
The followers route is the stronger choice in a few recurring situations:
- Studying a competitor's audience before you plan content or outreach.
- Finding the people who follow an influencer or publication in your niche.
- Seeing who a key account follows, which can reveal the sources it trusts.
- Building a prospect list from an audience that already exists, rather than from scratch.
A practical pairing is to run the keyword search first, find two or three accounts that clearly lead the conversation, and then search their followers. That second list begins with people who chose to follow the topic's leading voices.
Summing up Twitter user search on X
X's own search finds people by name, and that is the right tool for one person. A Twitter user search by keyword is a different job: it needs bios and tweet history read together, filters for activity, location and account age, and a way to export or list the result.
Circleboom's Deep X Account Search does that job through X's own data, with room for 5,000 public profiles per keyword and filters that stack. Live search, followers search and influencer search fill the gaps when timing, an existing audience or reach matters more than coverage.
Trust the count only after the first page has earned it.

Searching X users: frequently asked questions
Can I search Twitter bios only, without tweet matches?
Yes. Run the keyword search, then type the same word into Find in Bio & Name; accounts without it in their display name or bio drop out.
The case for bio-first searching is laid out in searching keywords in profiles, not tweets.
Can I export the X users I find?
Yes. Mark the accounts you want and hit Export for a CSV file.
Exports spend search tokens, so filter first. If you would rather read the accounts' posts on X without a file, Add to List can put them in a Twitter List.
