Operator syntax is fragmented across platforms

Every search platform invented its own grammar. Google uses prefix operators. PubMed uses bracketed field tags. GitHub mixes both. Stack Overflow adds tag syntax. The result: time lost to documentation lookups instead of finding what matters.

Google · prefix operators

Operators sit before a value, separated by a colon.

site:example.com filetype:pdf intitle:"annual report"

PubMed · bracketed field tags

Field tags follow each term in square brackets, joined by Boolean operators.

Validated registry

Each operator is verified against vendor documentation and live SERPs before being added to the full operator reference.

Who SearchOperators is for

Five professional workflows, one toolkit. Each card opens a working query in the builder.

Frequently asked questions

Is SearchOperators free?
Yes. The query builder, operator reference, and all guides are free to use without registration or sign-up.
Which search platforms are supported?
Nine platforms in total: Google, Bing, DuckDuckGo, Yandex, PubMed, Google Scholar, GitHub Search, Stack Overflow, and LinkedIn X-Ray.
How is SearchOperators different from Google Advanced Search?
Google Advanced Search covers a single engine and a small subset of operators. SearchOperators surfaces 100+ operators across 9 platforms — including PubMed field tags, GitHub code search, and LinkedIn X-Ray — with platform-specific syntax handled automatically.
Does SearchOperators store my queries?
By default, no. The builder runs entirely in the browser, and IP addresses and usage logs are not stored on the server. You can optionally publish a query — for example, an OSINT lookup or an SEO backlink-prospecting search — to share it with the community; published queries can be upvoted by other users.

Start with a single operator

The visual builder turns plain inputs into expert-level queries — across web engines, academic databases, code repositories, and recruiting tools — with compatibility checks built in.
