Boolean search strings for security guards: state license, armed or unarmed, post type and the cybersecurity trap

A security guard search works when the string names the state license the way guards write it (a California guard card, a Florida Class D with or without a Class G, a Texas non-commissioned or commissioned license, a New York security guard registration), whether the post is armed, and the post type: lobby access control, mobile patrol, hospital, event or port. "Security" alone returns cybersecurity analysts, securities brokers and Social Security staff as readily as guards, so every string needs a guard duty and a NOT block. As of November 2026, each state runs its own license and its own lookup, so the string finds candidates and the regulator's search confirms them.

Below are ten strings by state license and post type, and what LinkedIn, Indeed and Google support as of November 2026. For the operators themselves, see Boolean search strings for recruiters; for the first call, see the security guard screening questions.

State licenses, posts and credentials that change what a security guard search finds

• Armed or unarmed is the first block. Every state in the table licenses armed work separately, so an armed post needs the firearm credential in the string (exposed firearm permit, Class G, commissioned, armed guard) and an unarmed post should not require it. Other states differ again; check the job state's regulator. This is not legal advice.
• Post type is the second block. Corporate lobby officers write access control, badges, CCTV and visitor management; patrol officers write vehicle patrol, alarm response and lockups; hospital officers write emergency department, behavioral health and de-escalation; event staff write crowd management; port officers write TWIC.
• TWIC for ports. TSA's TWIC page says the Transportation Worker Identification Credential is for workers who need access to secure areas of the nation's maritime facilities and vessels, as of November 2026. Port and terminal guards list it, so it is a strong term for those posts and noise elsewhere.
• Supervisor and manager credentials. ASIS International's certification page lists four ANAB-accredited certifications: the Associate Protection Professional (APP), for people with at least a year of compensated security experience; the Certified Protection Professional (CPP) in security management; the Physical Security Professional (PSP); and the Professional Certified Investigator (PCI). The International Foundation for Protection Officers lists the Certified Protection Officer (CPO) and Certified in Security Supervision and Management (CSSM) programs. They belong in supervisor and manager searches; few guards hold them.

Ten Boolean strings by state license and post type

Swap in the state license, post type and city from your own intake; these are examples. Each searches on licenses and duties, and none should be edited to add a term that stands in for age, sex, race, religion, national origin, disability or veteran status.

By state license

1. California unarmed guard — Indeed Smart Sourcing
("security guard" OR "security officer" OR "unarmed security") AND skill: ("guard card" OR bsis OR "security guard registration") AND ("access control" OR patrol OR "incident reports") NOT (cybersecurity OR "information security")

2. Florida armed officer — Indeed Smart Sourcing
("armed security officer" OR "armed security guard" OR "security officer") AND ("class g" OR "g license") AND ("class d" OR "d license") NOT (cybersecurity OR "loss prevention")

3. Texas commissioned officer — Indeed Smart Sourcing
("commissioned security officer" OR "armed security officer") AND ("level iii" OR "level 3" OR commissioned) AND (houston OR dallas OR "san antonio" OR austin) NOT (cybersecurity OR "information security")

4. New York registered guard — Indeed Smart Sourcing
("security guard" OR "security officer") AND ("guard license" OR "guard registration" OR "8 hour" OR "16 hour") AND ("new york" OR nyc OR brooklyn OR queens) NOT (cybersecurity OR "loss prevention")

By post type

5. Corporate lobby and access control — LinkedIn general search
("security officer" OR "concierge security" OR "lobby security officer") AND ("access control" OR "badge access" OR cctv OR "visitor management") NOT (cybersecurity OR "information security" OR "security engineer")

6. Mobile patrol officer — Indeed Smart Sourcing
("patrol officer" OR "mobile patrol" OR "security officer") AND skill: ("vehicle patrol" OR "mobile patrol" OR "alarm response" OR lockups) NOT ("police officer" OR deputy OR "border patrol")

7. Hospital security officer — LinkedIn general search
("hospital security officer" OR "healthcare security officer" OR "security officer") AND (hospital OR "emergency department" OR "behavioral health") AND ("de-escalation" OR "crisis intervention" OR "workplace violence") NOT (nurse OR "information security")

8. Port or terminal security with TWIC — Indeed Smart Sourcing
("security officer" OR "security guard" OR "gate officer") AND (twic OR "transportation worker identification credential") AND (port OR terminal OR maritime OR vessel) NOT ("truck driver" OR longshoreman)

Supervisors and search-engine X-ray

9. Site supervisor or account manager — LinkedIn Recruiter, Job titles + Keywords filters
("security site supervisor" OR "security supervisor" OR "security account manager" OR "field supervisor") AND ("post orders" OR scheduling OR "client relations") AND ("security officers" OR "associate protection professional" OR "certified protection officer" OR psp) NOT (cybersecurity OR "information security")

10. Public profiles by license and city — Google X-ray
site:linkedin.com/in ("security officer" OR "security guard") "guard card" "los angeles" -jobs -recruiter -cybersecurity

Hourly guards keep resumes on job boards far more often than on public profiles, so the X-ray suits supervisors and specialized posts better than line officers. Treat what it returns as leads to check.

What LinkedIn, Indeed and Google actually support

As of November 2026, LinkedIn's Boolean help page requires AND, OR and NOT in capitals, supports quotes and parentheses, and evaluates quoted phrases first, then parentheses, NOT, AND and OR. It does not support wildcards, so "security guard" and "security officer," "class d" and "d license," and "level iii" and "level 3" all have to be written out. LinkedIn Recruiter's Boolean page lists Job titles, Location, Companies and Keywords among the fields that take Boolean, which helps string 9 split titles from duties, and warns that too many facets in one query can cause a search result issue.

Indeed's Smart Sourcing guide for administrative and business operations roles documents AND, OR, NOT, quotes, parentheses and the skill: field, and notes that a city name also matches people who used to live or work there unless you add "lives in." Line officers are more likely to have an Indeed resume than a LinkedIn profile, which is why most strings here are written for Indeed. Google's search operators page documents quotes, site:, the minus sign and filetype:, but not OR, so test the OR block in string 10.

Narrowing by state, shift and seniority

The license is tied to the state, so location matters twice: the post's commute, and the state whose license the guard holds. A guard who just moved may hold a license from the old state that will not appear in the new state's lookup; ask which state's license they hold and check the job state's rule before you submit them. Many contract posts are nights, weekends or rotating shifts, and words such as "overnight" or "graveyard" only find people who wrote them, so confirm availability on the call instead of filtering on it.

Seniority shows in words such as "site supervisor," "shift lead," "field supervisor," "trained new officers," "wrote post orders" and "client walkthroughs," over "standing post" alone. LinkedIn's page on premium search filters lists Years of Experience as a filter only in Recruiter and Sales Navigator; on Indeed or a basic account, the supervisor phrases carry that signal.

False positives worth excluding with NOT

• Cybersecurity and information security. "Security analyst," "SOC analyst," "security engineer" and "information security" profiles flood any string built on the word security. Exclude them every time, and use Boolean search strings for cybersecurity roles for that work.
• Securities, Social Security and clearances. Brokers write "securities," benefits staff write "Social Security," and defense and IT staff write "security clearance." Exclude each when it shows up in your results.
• Alarm and security systems technicians. Installers write access control and CCTV because they install it. Exclude technician, installer and "low voltage."
• Retail loss prevention. Loss prevention and asset protection staff work for retailers on theft, not posts. Exclude them unless the client is hiring for that.
• Sworn officers, only when the client says so. Police, deputies and corrections officers share patrol and report-writing words. Florida's Class D page lists training exemptions for certain current or former law enforcement and corrections officers, so they can be a real pool; exclude them only at the client's request.
• Acronym collisions. CPP is also the Certified Payroll Professional, APP matches every mobile app and CPO is also a chief privacy or product officer. Spell the security credentials out, as string 9 does.
• Recruiters. Security staffing recruiters repeat every license and post term. Exclude recruiter.

Two lines to keep out of every string: veteran or military terms, which target veteran status, and anything meant to screen criminal history. Licensing checks are run by the state (California's registration requires a Live Scan check), and your own checks follow the FCRA process and any fair chance law, covered in ban-the-box interview questions. The EEOC rescinded its 2012 arrest and conviction records guidance on October 28, 2026, but Title VII and state and city fair chance laws still apply.

A worked example: three passes on a hospital security search

An invented search, shown as it actually gets narrowed.

The license block made the list placeable; the post block made it fit. On most guard searches, the post block is what the client will judge the submittal on.

What a search cannot verify

A string can find someone whose profile names the right license, post and duties. It cannot confirm the license or firearm permit is active, show how they write an incident report, or tell you how they handle a confrontation at 3 a.m. Check every license in the state's lookup, then use the security guard screening questions on the call, the security guard job description template to fix armed status, post and shift before you search, the interview guide for security officer roles for later rounds, and the security officer supervisor screening questions when string 9 finds a supervisor.
