== Search geographic data
|
|
|
|
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 <<kuery-query,{kib} Query Language>>. Set the time filter to restrict layers by time.
|
|
|
|
This image shows an example of global search and global time narrowing results.

|
|
|
Only layers requesting data from {es} are narrowed by global search and global time.
|
|
To add a layer that requests data from {es} to your map, click *Add layer*, then select one of the following:
|
|
|
|
* Documents
|
|
|
|
* Choropleth
|
|
|
|
* Clusters and grid
|
|
|
|

|
|
==== Narrow layers by global search
|
|
|
|
Layers that request data from {es} are narrowed when you submit a <<kibana-concepts-searching-your-data, search>>.
|
|
Layers narrowed by semi-structured search and filters contain the filter icon image:maps/images/filter_icon.png[] next to the layer name in the legend.
|
|
|
|
To prevent the global search from applying to a layer, configure the following:
|
|
|
|
* In *Filtering*, clear the *Apply global search to layer data* checkbox to turn off global search for the layer source.
|
|
|
|
* In *Term joins*, clear the *Apply global search to join* checkbox to turn off global search for the <<terms-join, term join>>.
|
|
|

[[maps-narrow-layer-by-global-time]]
|
|
==== Narrow layers by global time
|
|
|
|
Layers that request data from {es} using a <<data-views, data view>> with a configured time field are narrowed by the <<set-time-filter, global time>>.
|
|
These layers contain the clock icon image:maps/images/clock_icon.png[clock icon] next to the layer name in the legend.
|
|
|
|
Use the time slider to quickly select time slices within the global time range:
|
|
|
|
. Click image:maps/images/timeslider_toggle_icon.png[timeslider icon] to open the time slider.
|
|
. Click previous and next buttons to advance the time slice backward or forward.
|
|
. Click play to animate your spatial temporal data.
|
|
|
|
To prevent the global time filter from applying to a layer, configure the following:
|
|
|
|
* In *Filtering*, clear the *Apply global time to layer data* checkbox to turn off the global time for the layer source.
|
|
|
|
* In *Term joins*, clear the *Apply global time to join* checkbox to turn off the global time for the <<terms-join, term join>>.

[[maps-refresh-layer]]
|
|
==== Refresh layer data
|
|
|
|
Layers that request data from {es} re-fetch data when <<set-time-filter, automatic refresh>> fires and when you click *Refresh*.
|
|
|
|
To prevent refreshing layer data, configure the following:
|
|
|
|
* In *Filtering*, clear the *Apply global refresh to layer data* checkbox to turn off refresh for the layer source.

[[maps-create-filter-from-map]]
|
|
=== Create filters from a map
|
|
|
|
Create filters from your map to focus in on just the data you want. *Maps* provides three ways to create filters:
|
|
|
|
* <<maps-map-extent-filter>>
|
|
* <<maps-spatial-filters>>
|
|
* <<maps-phrase-filter>>
|
|
|

|
[[maps-map-extent-filter]]
|
|
==== Filter dashboard by map extent
|
|
|
|
A map extent shows uniform data across all panels.
|
|
As you pan and zoom your map, all panels will update to only include data that is visible in your map.
|
|
|
|
To enable filtering your dashboard by map extent:
|
|
|
|
* Open the main menu, and then click *Dashboard*.
|
|
* Select your dashboard from the list or click *Create dashboard*.
|
|
* If your dashboard does not have a map, add a map panel.
|
|
* Click the gear icon image:maps/images/gear_icon.png[gear icon] to open the map panel menu.
|
|
* Select *More* to view all panel options.
|
|
* Select *Enable filter by map extent*.

[[maps-spatial-filters]]
|
|
==== Spatial filters
|
|
|
|
A spatial filter narrows search results to documents that either intersect with, are within, or do not intersect with the specified geometry.
|
|
|
|
You can create spatial filters in two ways:
|
|
|
|
* Click the tool icon image:maps/images/tools_icon.png[], and then draw a shape, bounding box, or distance on the map to define the spatial filter.
|
|
* Click *Filter by geometry* in a <<maps-vector-tooltip-locking, locked tooltip>>, and then use the feature's geometry for the spatial filter.
|
|
|
|
Spatial filters have the following properties:
|
|
|
|
* *Geometry label* enables you to provide a meaningful name for your spatial filter.
|
|
* *Spatial relation* determines the {ref}/query-dsl-geo-shape-query.html#_spatial_relations[spatial relation operator] to use at search time.
|
|
* *Action* specifies whether to apply the filter to the current view or to a drilldown action. Only available when the map is a panel in a {kibana-ref}/dashboard.html[dashboard] with {kibana-ref}/drilldowns.html[drilldowns].

[[maps-phrase-filter]]
|
|
==== Phrase filters
|
|
|
|
A phrase filter narrows search results to documents that contain the specified text.
|
|
You can create a phrase filter by clicking the plus icon image:maps/images/gs_plus_icon.png[] in a <<maps-vector-tooltip-locking, locked tooltip>>.
|
|
If the map is a dashboard panel with drilldowns, you can apply a phrase filter to a drilldown by selecting the drilldown action.

[[maps-layer-based-filtering]]
|
|
=== Filter a single layer
|
|
|
|
You can apply a search request to individual layers by setting `Filters` in the layer details panel.
|
|
Click the *Add filter* button to add a filter to a layer.
|
|
|
|
NOTE: Layer filters are not applied to *term joins*. You can apply a search request to *term joins* by setting the *where* clause in the join definition.

[[maps-search-across-multiple-indices]]
|
|
=== Search across multiple indices
|
|
|
|
Your map might contain multiple {es} indices.
|
|
This can occur when your map contains two or more layers with {es} sources from different indices.
|
|
This can also occur with a single layer with an {es} source and a <<terms-join>>.
|
|
|
|
Searching across multiple indices might sometimes result in empty layers.
|
|
The most common cause for empty layers are searches for a field that exists in one index, but does not exist in other indices.
|
|
|
|

[[maps-disable-search-for-layer]]
|
|
==== Disable global search for a layer
|
|
|
|
One strategy for eliminating unintentional empty layers from a cross index search is to <<maps-narrow-layer-by-global-search, disable global search for a layer>>.
|
|
|
|
[float]
|
|
[[maps-add-index-search]]
|
|
==== Use _index in a search
|
|
|
|
Add {ref}/mapping-index-field.html[_index] to your search to include documents from indices that do not contain a search field.
|
|
|
|
For example, suppose you have a vector layer showing the `kibana_sample_data_logs` documents
|
|
and another vector layer with `kibana_sample_data_flights` documents.
|
|
(See <<add-sample-data, adding sample data>>
|
|
to install the `kibana_sample_data_logs` and `kibana_sample_data_flights` indices.)
|
|
|
|
If you query for
|
|
--------------------------------------------------
|
|
machine.os.keyword : "osx"
|
|
--------------------------------------------------
|
|
the `kibana_sample_data_flights` layer is empty because the index
|
|
`kibana_sample_data_flights` does not contain the field `machine.os.keyword` and no documents match the query.
|
|
|
|
[role="screenshot"]
|
|
image::maps/images/global_search_multiple_indices_query1.png[]
|
|
|
|
If you instead query for
|
|
--------------------------------------------------
|
|
machine.os.keyword : "osx" or _index : "kibana_sample_data_flights"
|
|
--------------------------------------------------
|
|
the `kibana_sample_data_flights` layer includes data.
