How numeric groups A/B/C work:

Each numeric filter belongs to one of the groups A, B, or C.

  • All filters inside the same group are combined using AND.
  • The groups themselves are combined using OR.
  • This produces a structure like:
    (A1 AND A2) OR (B1 AND B2) OR (C1)
  • Global filters (text search, minimum observations, “only orbits”) apply before the groups.
Examples:
  • If Filter 1 and Filter 2 are in group A, and Filter 3 is in group B, the query is: (Filter1 AND Filter2) OR (Filter3)
  • If Filter 1, Filter 2, Filter 3 and Filter 4 are in the same group A, the query is: Filter1 AND Filter2 AND Filter3 AND Filter4
