LinkedIn supports a reduced set of boolean operators. They work in the content search box, which is the one that matters for finding buying signals.
The operators
- Quotes — "month end close" matches the exact phrase.
- AND — both terms must appear. Often implicit.
- OR — either term. Useful for synonyms buyers use interchangeably.
- NOT — excludes. The fastest way to remove vendors from your results.
- Parentheses — group clauses: ("fractional CFO" OR "part time CFO") NOT hiring.
Searches worth keeping
The best searches describe a symptom in the buyer's own words and exclude the vocabulary vendors use. Start from sentences real customers said to you.
There is a term limit, and it fails silently
A content search carrying too many operators returns nothing at all rather than an error, which is indistinguishable from a topic nobody posts about. Roughly six terms is the practical ceiling — three phrases joined by OR plus three exclusions works reliably. If a search you expect to match comes back empty, drop one exclusion before rewriting anything.
Filtering by date
Content older than a week is rarely worth acting on — the moment has passed. Sort by recent and treat anything beyond that as reference rather than a lead.

Install it, run one search, and save five people. That is the whole first session.
