Boolean search strings for home health aides: the 42 CFR 484.80 pathways, title variants and the HHA collision

Home health aide searches start with an abbreviation that points at the employer. "HHA" is how aides sometimes describe themselves, but it is also the standard abbreviation for a home health agency, so it returns agency owners, administrators, intake coordinators and billing staff. "Aide" on its own returns legislative aides and teacher's aides. And a clean list still mixes three groups the client may not treat the same way: aides qualified for a Medicare-certified agency, CNAs who could qualify through the nurse aide registry, and caregivers from non-medical home care.

The agency type and the training pathway separate them. Below are ten strings built around both, and what Indeed, LinkedIn and Google support as of October 2026. For the screen that follows, see the home health aide screening questions.

The federal pathways that change what an aide search finds

For Medicare-certified home health agencies, 42 CFR 484.80 sets who counts as a qualified home health aide. As of October 2026, paragraph (a)(1) allows four routes:

• Training and competency evaluation. A program meeting paragraphs (b) and (c): at least 75 hours of classroom and supervised practical training, with at least 16 hours of classroom training before at least 16 hours of supervised practical training, followed by a competency evaluation performed by a registered nurse.
• Competency evaluation only. Someone who passes a competency evaluation that meets paragraph (c).
• The nurse aide route. Someone who completed a state-approved nurse aide training and competency evaluation program and is currently listed in good standing on the state nurse aide registry. This is why CNAs belong in many HHA searches.
• A state licensure program that meets paragraphs (b) and (c).

Two more rules matter for sourcing. Under paragraph (a)(2), an aide who has gone 24 consecutive months without providing covered services for pay since completing the program must complete another program before providing services. Under paragraph (d), aides need at least 12 hours of in-service training in each 12-month period. Non-medical home care agencies follow state rules instead, and states can require more than the federal minimum. This is not legal advice.

Ten Boolean strings by agency type and skill

Swap in the agency type, area and schedule from your own intake; these are examples.

Medicare-certified home health

1. Qualified home health aide — Indeed Smart Sourcing
("home health aide" OR "certified home health aide" OR "home health aid") AND skill: ("personal care" OR "activities of daily living" OR adls OR "vital signs") NOT ("home health agency administrator" OR "intake coordinator" OR biller)

2. CNA on the registry for an HHA role — Indeed Smart Sourcing
("certified nursing assistant" OR cna OR "nurse aide") AND skill: ("home health" OR "home care" OR "in-home care") AND (registry OR "active certification" OR "in good standing")

3. Recent paid experience — LinkedIn general search
("home health aide" OR "certified nursing assistant" OR cna) AND ("home health" OR "home care") AND (2025 OR 2026 OR present) NOT (recruiter OR administrator OR "office manager")

Skills and populations

4. Transfers and mobility — Indeed Smart Sourcing
("home health aide" OR "personal care aide" OR caregiver) AND skill: ("hoyer lift" OR "mechanical lift" OR "safe transfers" OR "gait belt")

5. Dementia care — Indeed Smart Sourcing
("home health aide" OR caregiver OR "personal care aide") AND skill: (dementia OR alzheimer's OR "memory care") AND ("home care" OR "in-home")

6. Hospice aide — LinkedIn general search
("hospice aide" OR "home health aide" OR "hospice cna") AND (hospice OR "end of life" OR "palliative care") NOT (chaplain OR "social worker" OR "hospice nurse")

7. Pediatric home care — Indeed Smart Sourcing
("home health aide" OR "pediatric home health aide" OR cna) AND skill: (pediatrics OR "pediatric home care" OR "trach care" OR "g-tube")

Non-medical home care, schedule and X-ray

8. Personal care aide for a non-medical agency — Indeed Smart Sourcing
("personal care aide" OR "personal care assistant" OR caregiver OR "home care aide") AND skill: ("meal preparation" OR "light housekeeping" OR companionship OR "medication reminders") NOT ("principal component analysis" OR "family caregiver")

9. Live-in or weekend coverage — Indeed Smart Sourcing
("home health aide" OR caregiver OR "home care aide") AND ("live-in" OR weekends OR "overnight shifts" OR "24-hour care") AND skill: ("personal care" OR adls)

10. Public profiles by county — Google X-ray
site:linkedin.com/in "home health aide" "certified" "cook county" -jobs -recruiter -agency

Most of these strings are written for Indeed because they lean on its skills field. To run one on LinkedIn, drop skill: and keep the same terms in the Keywords box; to run it as a Google X-ray, cut it down to one title and one skill per query.

What Indeed, LinkedIn and Google actually support

Indeed's healthcare Boolean guide shows AND, OR, NOT, quotes and parentheses, a skill: field for the skills section, and fieldofstudy: and school: for education, as of October 2026. Putting ADLs, lifts and dementia care behind skill: matches aides who list them as skills rather than every profile that mentions them in passing, which is why most strings here use it.

LinkedIn's Boolean help page requires capital AND, OR and NOT, supports quotes and parentheses, and does not support wildcards. Aides write "home health aide," "home health aid," "HHA" and "home care aide," and the misspelling is common enough to keep in the OR block. LinkedIn Recruiter's Boolean page warns that too many facets in one query can cause problems.

Google's search operators page documents quotes, site:, the minus sign and filetype:, but not OR. Exclude "agency" in an X-ray, as string 10 does, to cut agency pages and owners.

Narrowing by agency type, territory and schedule

Ask first whether the client is a Medicare-certified home health agency, a hospice, or a non-medical home care agency. That answer decides whether the federal pathways above apply, whether CNAs on the registry count, and whether caregivers with no formal training are in scope at all. Then ask which state rules apply on top.

Territory comes next. Home health is visit-based, so drive time and transport matter more than in facility work. Use the platform's location radius around the client's service area rather than a city name, and ask on the call whether the aide has reliable transport.

Schedule decides many placements. Some aides want a fixed set of clients and hours; others take live-in, overnight or weekend cases. Put schedule words in the string only when the case requires them, as in string 9, and record availability on every call.

False positives worth excluding with NOT

• The HHA collision. Home health agency owners, administrators and directors match HHA. Search the full title, and exclude "administrator," "director of operations" and "owner."
• Other kinds of aide. Legislative aides, teacher's aides and pharmacy aides match "aide." Always pair the word with "home health," "home care" or "personal care."
• Family caregivers. People caring for a relative write "caregiver" without being employable as an aide. Exclude "family caregiver" and ask about paid experience.
• Home health clinicians. Home health RNs, PTs and OTs list the same agencies. Exclude "registered nurse," "physical therapist" and "occupational therapist."
• Office staff and recruiters. Schedulers, intake coordinators and recruiters at agencies list aide terms all day. Exclude them by title.

A worked example: three passes on a certified agency search

An invented search, shown as it actually gets narrowed.

Spelling out the title removed the agency noise, and the pathway question on the call did what no string can: establish whether the aide is qualified.

What a search cannot verify

A string can find someone whose profile names the right skills and setting. It cannot confirm the training pathway, a registry listing, recent paid work or how the aide handles a client who refuses care. The home health aide screening questions cover those, the home health aide job description template helps the client state its requirements, the caregiver screening questions cover non-medical roles, and the Boolean strings for CNAs cover the registry pool in depth.
