Voyager Search can index records' geometries from databases,such as Oracle Spatial, MSSQL, SDE and PostgreSQL/PostGIS, that support spatial content and operations. However in some cases, notably PostGIS, geometries are not extracted as geometric objects from the database, but you can use the database's native spatial functions to convert them in to a Well-Known-Text (WKT) geometry which Voyager can use to interpret location and shape.
To index Records with Geometry from a Spatial Database (PostGIS):
ST_AsText()
to transform the geometric string into a WKT (Well-Known Text) representation of the geometry
