# Tips & Notes

- **Category Keywords:** AI-assigned thematic categories grouping related documents (e.g.,
  "Environmental Policy", "Securities Regulations").
- **Suggested Searches:** Topics curated by the Federal Register itself. Use these to track specific
  regulatory areas the Federal Register considers noteworthy.
- **Date Ranges:** Activity tools default to the last 30 days; document tools default to today. Any
  date range can be customized.
- **Multi-Select Filters:** Select multiple values from any dropdown, or choose "All" to include
  everything.
- **Charts:** Horizontal bar charts show up to the top 15 items by total count. Hover over segments
  for a detailed tooltip with totals.
- **No Weekend Data:** The Federal Register is not published on weekends or federal holidays, so
  selecting those dates will return no results.
