Boolean search strings for administrative assistants: setting, software skills and the system administrator collision

An administrative assistant search fails in two predictable ways. Unquoted, "administrative" and "admin" pull in system, network and database administrators, and "assistant" pulls in medical, dental, teaching and physician assistants. Quoted but bare, the title returns tens of thousands of similar profiles, because what separates a good fit is the setting (corporate, medical, legal, school, construction) and the software and tasks of that setting. As of November 2026, LinkedIn's Boolean search supports capitalized AND, OR and NOT with quotes and parentheses and no wildcards, so "administrative," "administration" and "admin" each have to be written out.

Below are ten strings by setting, and what LinkedIn, Indeed and Google support as of November 2026. For assistants who support a C-suite executive, see Boolean search strings for executive assistants; for the person who runs the whole office, see Boolean search strings for office managers.

Titles, settings and credentials that change what an administrative assistant search finds

• The official title list. O*NET's profile for Secretaries and Administrative Assistants, Except Legal, Medical, and Executive (43-6014.00) lists, as of November 2026, Administrative Assistant, Administrative Clerk, Administrative Secretary, Administrative Specialist, Administrative Support Assistant, Administrative Technician, Department Secretary, Office Assistant, Secretary and Staff Assistant among its reported titles. That is a ready-made OR block.
• The four groups BLS uses. The Bureau of Labor Statistics' Occupational Outlook Handbook splits the job into executive, legal, medical and all other secretaries and administrative assistants, the last being the largest group and including schools. The same split works for strings: decide which one the client means before you search.
• CAP. IAAP's Certified Administrative Professional requires an exam plus paid administrative experience that falls as education rises, from four years with no degree to two with a bachelor's, according to IAAP's page as of November 2026. It is a positive signal, rarely a requirement.
• Microsoft Office Specialist. Certiport's Microsoft 365 Apps exams include Excel Associate and Expert, Word Associate and Expert, and PowerPoint Associate as of November 2026; Outlook appears only as an Office 2019 exam. Candidates write "MOS," "Microsoft Office Specialist" or "Excel Expert."
• Medical administrative credential. NHA's Certified Medical Administrative Assistant (CMAA) requires a training program or supervised work experience and is renewed every two years with 10 continuing education credits, as of November 2026. NHA's separate Certified Clinical Medical Assistant (CCMA) is the clinical credential, which is useful when you need to tell the two apart.
• Notary public is state-specific. Some offices want an assistant who can notarize. Each state commissions its own notaries; California's Secretary of State, for example, grants four-year commissions, as of November 2026. Search "notary public" with the state, and confirm the commission with that state.

Ten Boolean strings by setting

Swap in the software, setting and metro from your own intake; these are examples. Each one searches on setting, tasks and tools, and none should be edited to add a term that stands in for age, sex, race, religion, national origin, disability or veteran status.

Corporate and department support

1. Corporate administrative assistant — LinkedIn general search
("administrative assistant" OR "admin assistant" OR "administrative coordinator" OR "office assistant") AND ("calendar management" OR scheduling OR "meeting coordination") AND (excel OR "microsoft office" OR "google workspace") NOT ("system administrator" OR "network administrator" OR "medical assistant")

2. Department or team assistant — Indeed Smart Sourcing
("administrative assistant" OR "department secretary" OR "staff assistant") AND skill: ("expense reports" OR "travel arrangements" OR "purchase orders") AND (excel OR "data entry")

3. Assistant with real spreadsheet depth — LinkedIn Recruiter, Keywords filter
("administrative assistant" OR "administrative specialist" OR "administrative coordinator") AND ("pivot tables" OR vlookup OR xlookup OR "excel expert" OR "microsoft office specialist") NOT ("data analyst" OR "financial analyst" OR "database administrator")

Medical, legal, school and construction

4. Medical administrative assistant — Indeed Smart Sourcing
("medical administrative assistant" OR "medical secretary" OR "medical office assistant") AND skill: ("medical terminology" OR "insurance verification" OR ehr) NOT ("clinical medical assistant" OR phlebotomy OR vitals)

5. Legal administrative assistant — LinkedIn general search
("legal administrative assistant" OR "legal secretary" OR "legal assistant") AND ("law firm" OR attorneys) AND ("court filings" OR "e-filing" OR "document management") NOT ("senior paralegal" OR "associate attorney" OR student)

6. School secretary or front office assistant — LinkedIn general search
("school secretary" OR "school administrative assistant" OR "front office assistant") AND (attendance OR enrollment OR "student records") AND (school OR district) NOT (teacher OR "teaching assistant")

7. Construction project administrator — Indeed Smart Sourcing
("project administrator" OR "construction administrative assistant" OR "project coordinator") AND skill: (submittals OR rfis OR "certified payroll") AND (construction OR contractor)

Credentials and X-ray

8. Assistant with a credential — LinkedIn Recruiter, Keywords filter
("administrative assistant" OR "administrative professional" OR "office assistant") AND ("certified administrative professional" OR iaap OR "microsoft office specialist" OR cmaa OR "notary public")

9. Public profiles by setting and metro — Google X-ray
site:linkedin.com/in "administrative assistant" "calendar management" "excel" "phoenix" -jobs -recruiter -"system administrator"

10. Public resumes — Google X-ray, filetype search
filetype:pdf "administrative assistant" resume "expense reports" "travel" -template -sample -"system administrator"

Both X-rays use only operators Google documents and reach only what is public and indexed. Resume PDFs in particular can be years old, so treat the results as leads, not a shortlist.

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, matches quoted phrases before any other logic, does not support wildcards, and does not officially support the + and - symbols. LinkedIn Recruiter's Boolean page lists Job titles, Companies, Skills and Assessments, Schools, Industries and Spoken languages among the filters with Must have, Can have and Doesn't have options, and says stop words such as "to," "for" and "with" are ignored in Keywords. A phrase like "assistant to the director" therefore runs looser in Keywords than it reads; put it in Job titles instead.

Indeed's Smart Sourcing guide for administrative and business operations roles documents AND, OR, NOT, quotes, parentheses, a skill: field for the skills section of a resume and a fieldofstudy: field, and gives administrative assistant examples that pair the title with a skill: block of Excel or organization skills, as strings 2, 4 and 7 do. Google's search operators page documents quotes, site:, the minus sign and filetype:, but not OR, so the two X-rays here use none.

Narrowing by setting, software and seniority

Ask the client three things before writing the string: whom the assistant supports (one manager, a team, a department, the public), which systems they will use on day one, and how much of the day is phones and visitors versus documents and data. A role that is mostly phones and visitors is closer to a receptionist search, and the receptionist screening questions fit it better. A role that is mostly spreadsheets and reports needs string 3's skill block, not more title variants.

Seniority shows in scope words: "supported a department of," "trained new staff," "managed the calendar for," "coordinated events for," "office procedures." Language skills belong in the string only when the job requires them; LinkedIn Recruiter's Spoken languages filter is the place for that, and it should never be used as a stand-in for national origin. LinkedIn's premium search filters page lists Years of Experience and Seniority Level as Recruiter and Sales Navigator filters, as of November 2026.

False positives worth excluding with NOT

• IT administrators. "System administrator," "network administrator," "database administrator" and "Salesforce admin" collide with any unquoted administrative or admin. Exclude them by full title.
• Clinical assistants. "Medical assistant," "dental assistant," "physician assistant," "pharmacy assistant" and "teaching assistant" share the word assistant. For medical administrative roles, exclude clinical terms rather than "medical," which the right candidates also write.
• Paralegals, for legal support roles. Legal secretaries and paralegals share firms and software but do different work; see Boolean search strings for paralegals when the client actually wants paralegal work.
• Executive assistants, for entry-level roles. Senior EAs often list "administrative assistant" as an early job. Exclude "executive assistant" when the role is junior and the budget is too.
• Virtual assistant freelancers, when the role is employed. Keep them only if the client is open to that background.
• Staffing recruiters. Administrative staffing recruiters list every title above. Exclude "recruiter" and "staffing."

A worked example: three passes on a legal administrative assistant search

An invented search, shown as it actually gets narrowed.

The setting block found law firm assistants; the litigation block found the ones who have done this version of the job. For support roles, the setting is often the real requirement.

What a search cannot verify

A string can find someone whose profile names the right setting, tasks and software. It cannot show how accurately they work, how they handle three people's competing requests, or whether "advanced Excel" means pivot tables or formatting. Confirm any credential with its issuer and test software skills after the call when the job depends on them. Then use the administrative assistant screening questions for the screen, the interview guide for administrative roles for later rounds, and the administrative assistant job description template and 30-60-90 day plan for administrative assistants to agree on scope with the client before you start.
