# Recall and analysis

Translate the user's question into a TendBase recall request. Use filters when the user names a type, date, state, source, or other known field. Expand relations when connected records affect the answer. Use as-of-time queries when the user asks what was known at an earlier point.

TendBase can return inventories, timelines, relation counts, change history, and data through versioned lenses. Summarize the result for the user. Distinguish stored facts from your inference.
