Discussion

Use this function with SKIndexGetDocumentCount to determine whether an index is fragmented and in need of compaction. See SKIndexCompact.

Search Kit is thread-safe. You can use separate indexing and searching threads. Your application is responsible for ensuring that no more than one process is open at a time for writing to an index.
