 Search across the layers in your map to focus on just the data you want. Combine free text search with field-based search using the [{{kib}} Query Language](../../explore-analyze/query-filter/languages/kql.md). Set the time filter to restrict layers by time. Draw a polygon on the map or use the shape from features to create spatial filters. Filter individual layers to compares facets.

+When [{{cps}}](/explore-analyze/cross-project-search.md) is enabled and you have [linked projects](/explore-analyze/cross-project-search/cross-project-search-link-projects.md), use the [{{cps-init}} scope selector](/explore-analyze/cross-project-search/cross-project-search-manage-scope.md#cps-in-kibana) to control which projects your map queries. All {{es}}-backed layers, including [vector layers](/explore-analyze/visualize/maps/vector-layer.md), joins, and [heat map layers](/explore-analyze/visualize/maps/heatmap-layer.md), pull data from linked projects based on the current {{cps}} scope. When you change the scope, these layers update to reflect the new set of projects.
+
+ES|QL layers additionally support query-level overrides using [`SET project_routing`](/explore-analyze/query-filter/languages/esql-kibana.md#esql-kibana-cps). When you embed a map in a dashboard and a layer uses a [project routing](/explore-analyze/cross-project-search/cross-project-search-project-routing.md) override, the map panel displays a **Custom CPS scope** badge. Refer to [View data from multiple projects](/explore-analyze/dashboards/using.md#dashboard-cps-scope) for details.
