LinkedIn search is the platform's tool for finding people, companies, jobs, posts, groups, and schools across its network. You use it by typing into the search bar at the top of any page, then narrowing results with the filter tabs (People, Jobs, Companies, Posts, and more) and the All filters panel. The most powerful version is people search, where you can filter by title, current and past company, location, industry, connection degree, and school — and combine terms with Boolean operators like AND, OR, NOT, and quotes for exact phrases. This complete guide covers every search type, the filters that matter, the Boolean syntax that makes results precise, saved searches and alerts, the free "commercial use limit" that quietly caps heavy searchers, a troubleshooting section for when search stops working, and how to search at scale without doing it by hand.
The search types, and when to use each
LinkedIn runs one search bar across several content types. After you search, use the tabs to switch between them:
- People — the workhorse for networking, recruiting, and sales. Rich filters, Boolean support. This is where most prospecting lives.
- Companies — find employers by industry, size, and location; a jumping-off point for employee search, and the fastest way to map an account before you reach in.
- Jobs — the job board, with filters for remote, salary, experience level, date posted, and easy-apply.
- Posts — search content by keyword to find live conversations, thought leaders, and warm outreach angles (someone posting about a problem you solve is a prospect raising their hand).
- Groups — find industry communities to join and, on some accounts, message members.
- Schools, Events, Services — narrower, but useful for alumni targeting, event-attendee outreach, and finding service providers.
Most prospecting and recruiting work lives in People and Companies, so that's where this guide spends its time — but knowing the Posts tab exists is a quiet edge, because content search finds people by what they care about right now, not just what their profile says.
People search filters that actually matter
Open All filters on a People search and you get a stack of options. The high-leverage ones:
- Connections (1st / 2nd / 3rd) — 2nd-degree is the sweet spot for outreach: reachable through a shared connection, but not already in your network.
- Connections of — everyone connected to a specific person; powerful for working a champion's network.
- Current company and Past company — isolate a target account, or find alumni of a company (great for warm angles).
- Title — the fastest way to find a role, especially paired with Boolean.
- Location — country, region, or metro.
- Industry and School — strong secondary filters for relevance and warm angles.
Free search vs. Sales Navigator: what each unlocks
The single biggest question people have is what they're missing on a free account. Here's the honest comparison:
| Capability | Free LinkedIn | Sales Navigator | |---|---|---| | Core filters (title, company, location, industry, school) | ✓ | ✓ | | Boolean search | ✓ | ✓ | | Connection-degree filter | ✓ | ✓ | | Seniority level filter | — | ✓ | | Company headcount / type filter | — | ✓ | | Years in role / at company filter | — | ✓ | | Recently changed jobs / posted / in news | — | ✓ | | Save searches + get new-match alerts | Jobs only | ✓ (people & accounts) | | Lead & account lists | — | ✓ | | Monthly search cap (commercial use limit) | Yes | No |
So free search handles most one-off and moderate prospecting; [Sales Navigator](/guides/linkedin-sales-navigator-cost) earns its price when you need the deeper filters (seniority, headcount, tenure) and saved-search alerts at volume. Our advanced search guide breaks down every filter individually.
Boolean search: the skill that separates good searchers from great ones
LinkedIn's search bar reads Boolean operators. Master five of them and your results transform. Note that the operators AND, OR, NOT must be typed in uppercase — lowercase is treated as a normal word.
- Quotes — exact phrase:
"vice president of sales" - AND — both terms required:
python AND django - OR — either term:
founder OR "co-founder" OR ceo - NOT — exclude a term:
recruiter NOT agency - Parentheses — group logic:
(cto OR "vp engineering") AND fintech
A few syntax rules worth knowing: there's no wildcard operator (use OR with variations instead, e.g. optimize OR optimise); search is not case-sensitive for the terms themselves; and you can put Boolean into the keyword field or the dedicated title/company fields under All filters, which is usually more accurate than the global bar.
Boolean recipes you can copy
- Senior marketing leaders, no juniors:
("head of marketing" OR "marketing director" OR CMO) NOT (assistant OR coordinator OR intern) - Founders and owners:
founder OR "co-founder" OR owner OR "managing director" - Technical decision-makers at startups:
(CTO OR "VP engineering" OR "head of engineering") NOT (junior OR intern) - HR/people leaders:
("head of people" OR "head of talent" OR CHRO OR "VP HR") - Exclude agencies/recruiters when prospecting: append
NOT (recruiter OR agency OR staffing)
Keep it to a handful of operators — overlong Boolean strings sometimes return fewer results, not more.
Saved searches and alerts
On a free account you can't save people searches, but you can save job searches and get alerts on new postings. On Sales Navigator, you can save both people and account searches and receive alerts whenever new profiles match your criteria — which turns prospecting from a manual re-run into a feed of fresh leads. If you find yourself running the same search every week, that alerting is one of the more concrete reasons to consider the paid tier.
The commercial use limit (why heavy search suddenly stops)
If you search a lot on a free account, you'll eventually see a message that you've hit your commercial use limit. LinkedIn caps how many searches a free account can run each month when the activity looks like recruiting or sales prospecting. The exact number isn't published, it varies by account, and it resets at the start of each calendar month.
To lift it, you upgrade: [LinkedIn Premium](/guides/linkedin-premium) raises the ceiling and adds visibility features, while Sales Navigator removes the standard cap and adds the advanced filters. If you keep bumping into the limit, that's the signal you've outgrown free search — see our Premium cost breakdown to decide which tier fits.
Searching by name, company, or email
When you're after one specific person rather than a type, the method depends on what you know: search the name and add a Current company filter to disambiguate; search the company and browse its People tab; or search by email (paste it, or import contacts) for the most precise match. The full playbook is in search by name, company, or email.
Searching without an account
You can see limited public profiles logged out, but real search — filters, Boolean, People results — requires an account. The reliable logged-out workaround is a search engine: "Full Name" site:linkedin.com. See how to search LinkedIn without an account for what's possible and where the limits bite.
Troubleshooting: why your LinkedIn search isn't working
A few common problems and fixes:
- "You've reached the commercial use limit." You've hit the free monthly search cap. Wait for the month to reset, or upgrade.
- Results seem incomplete or capped. Free search shows a limited number of results per query and hides some out-of-network profiles. Add filters to surface the ones that matter, or upgrade for fuller results.
- A person you know won't appear. Their privacy settings, a name change, or being outside your network can hide them. Try a former company, check spelling and nicknames, or search their email.
- Boolean isn't working. Make sure
AND/OR/NOTare uppercase and your quotes are straight quotes ("), not curly ones pasted from a document. - Results differ from a colleague's. Search is personalized by network, location, and connection degree — two people rarely see the identical list.
- Filters reset when you switch tabs. Filters are per result-type; re-apply them after moving between People, Jobs, and Companies.
Search for sales vs. recruiting vs. networking
The same tool, three different intents:
- Sales: filter by title + company + seniority to find decision-makers, then check the Posts tab for a current hook.
- Recruiting: lean on skills keywords, past companies, and schools; Recruiter Lite adds candidate-specific filters.
- Networking: 2nd-degree + industry + location finds reachable peers, and "Connections of" a mentor surfaces warm introductions.
Searching at scale, the practical way
Manual search is excellent for finding a few people. It's painful when you need to run the same search across dozens of companies, save everyone who qualifies, remember who you've already contacted, and follow up — that's hours of clicking and a spreadsheet that goes stale.
Conextly is built to close that gap for LinkedIn. It runs targeted searches, collects the matching people into an organized workspace, tracks every conversation so nothing slips, and drafts a personalized first message for each prospect — you approve every send. It turns "search, copy, paste, follow up" into a single reviewed workflow that stays under LinkedIn's limits and keeps every message yours. See Conextly's prospecting search.
