### Explanation
Beyond the obvious global search bar, most platforms ship multiple search interfaces — advanced operators (Twitter/X's `from:`, `since:`, `near:`; Facebook Graph Search remnants; LinkedIn Boolean syntax), in-app filters (search within a group, within someone's posts, within messages), and "unobvious" search affordances that aren't exposed in the UI but reachable by direct URL manipulation. Many platforms also expose secondary search endpoints for adjacent data: hashtags, places, events, products, jobs, saved items.
Investigators use these surfaces to fan out a single seed — a phrase, a date range, a location, a hashtag — into the population that touched it. The advanced operators are especially valuable because they scope by time and proximity in ways the normal UI hides: finding everyone who posted about a specific event in a specific 6-hour window near a specific city, for example. Familiarity with each platform's exact operator syntax is the main skill.
