How to Say "search" in Spanish
The most common Spanish word for “search” is “búsqueda” — use this for the general action or process of looking for something or someone, like finding lost items or information online..
búsqueda
Examples
La policía organizó una búsqueda del niño desaparecido.
The police organized a search for the missing child.
busque
/BOO-skeh//ˈbuske/

Examples
Espero que yo busque mi llave en el bolso.
I hope that I look for my key in the bag.
Señor López, ¡busque la información en internet!
Mr. Lopez, look for the information on the internet! (Uses 'usted busque'—Formal Command)
Ella necesita que su hermano busque el recibo.
She needs her brother to look for the receipt. (Uses 'él/ella busque'—Present Subjunctive)
The C-to-QU Rule
The verb 'buscar' ends in -car. To keep the hard 'k' sound when followed by 'e' (as in 'busque'), the 'c' changes to 'qu'. This happens in the special forms used for commands, wishes, and doubts.
Using 'Busque' as a Command
'Busque' is the polite, formal command form for 'usted' (you). Use it when addressing someone formally, like a boss or a stranger.
Forgetting the Spelling Change
Mistake: “Busce (instead of busque)”
Correction: The spelling must change to 'qu' before 'e' (busque) to make sure the 'c' doesn't sound like an 's' or 'th' sound.
busca
/BOOS-kah//ˈbuska/

Examples
La policía organizó una busca para encontrar al niño perdido.
