What's the proper way for me to define tsvector field in my schema file?

model DrawingSession {
  id          String                   @id @default(cuid())
  name        String
  description String?
  userId      String
  user        User                     @relation(fields: [userId], references: [id], onDelete: Cascade)
  data        Json
  isPublished Boolean                  @default(false)
  data_search Unsupported("tsvector")?

  createdAt DateTime @default(now())
  updatedAt DateTime @default(now()) @updatedAt
}

  const drawingsResult = await prisma.$queryRaw`
    SELECT "id", "name", "description", "data"
    FROM public."DrawingSession"
    WHERE "isPublished" = true
    AND "data_search" @@ to_tsquery('english', ${searchTerm})
    ORDER BY "id" ASC
    LIMIT ${take} OFFSET ${skip}
  `;
