Search becomes awkward when the only safe option is to decrypt everything locally and scroll. A stronger model lets teams search captured records while keeping the query and searchable text behind the workspace key boundary.
Most products treat search as a server privilege. The service indexes the text, stores the index, and answers the query in plain operational terms. That model is convenient. It is not especially disciplined when the records being searched are sensitive.
For evidence work, the better question is narrower: can a team retrieve relevant records quickly without turning the service into a plain-text search operator. That is the problem encrypted search is meant to solve.
