"Pencarian ini perlu diadakan."

Translation: This search needs to be held.

"This search needs to be CONDUCTED", hence the Indonesian sentence should read "Pencarian ini perlu DILAKSANAKAN".

"to conduct a search" is more natural than "to hold a search".

Guys I'm asking to the English natives, why can't we use "research" instead of search?

[S9N1t]

According to Google Translate, "pencarian" is search rather than "research", and the Indonesian word for "research" is penelitian. Btw, you're asking us, not asking to us.
