# `AshNeo4j.Functions.StContains`
[🔗](https://github.com/diffo-dev/ash_neo4j/blob/v0.7.0/lib/functions/st_contains.ex#L5)

Spatial containment — true if the first geometry contains the second.

v1 supports box-contains-point and box-contains-box:

    Place
    |> Ash.Query.filter(st_contains(bounds, ^test_point))
    |> Ash.read!()

    Place
    |> Ash.Query.filter(st_contains(bounds, ^test_box))
    |> Ash.read!()

Both forms push down to Neo4j's native `point.withinBBox`:
box-contains-point as a single call, box-contains-box as two ANDed calls
on the inner box's SW and NE corners (which is sufficient for axis-aligned
boxes — the other two corners are implied). `evaluate/1` covers the same
cases for in-memory fallback when pushdown isn't taken (e.g. expressions
the data layer can't recognise).

Named after the OGC / PostGIS convention (`ST_Contains`) for consistency
with ash_geo so consumer code reads the same across data layers.
