Using fields with docvalues (like `_doc`) for tie-breaking yields significantly better performance than using `_uid`, which lacks docvalues at the moment. The downside is that sorting by `_doc` by default is not stable under all conditions, but better than no tie-breaking at all. The new setting `context:tieBreakingFields` enables the user to customize the list of fields Kibana attempts to use for tie-breaking. The first field from that list, that is sortable in the current index pattern, will be used. It defaults to `_doc`, which should change to `_seq_no` from version 6.0 on. In addition to just showing a notification, errors that occur while loading documents from the database will be stored as part of the `loadingStatus` along with a reason code (if known). This is used to display more nuanced and helpful error messages to the user. The first such error message indicates a missing or invalid tiebreaker field required for sorting the context.

== Setting Advanced Options
|
|
|
|
The *Advanced Settings* page enables you to directly edit settings that control the behavior of the Kibana application.
|
|
For example, you can change the format used to display dates, specify the default index pattern, and set the precision
|
|
for displayed decimal values.
|
|
|
|
To set advanced options:
|
|
|
|
. Go to *Settings > Advanced*.
|
|
. Click the *Edit* button for the option you want to modify.
|
|
. Enter a new value for the option.
|
|
. Click the *Save* button.

WARNING: Modifying the following settings can significantly affect Kibana's performance and cause problems that are
|
|
difficult to diagnose. Setting a property's value to a blank field will revert to the default behavior, which may not be
|
|
compatible with other configuration settings. Deleting a custom setting removes it from Kibana permanently.

|
[horizontal]
|
|
`query:queryString:options`:: Options for the Lucene query string parser.
|
|
`sort:options`:: Options for the Elasticsearch {es-ref}search-request-sort.html[sort] parameter.
|
|
`dateFormat`:: The format to use for displaying pretty-formatted dates.
|
|
`dateFormat:tz`:: The timezone that Kibana uses. The default value of `Browser` uses the timezone detected by the browser.
|
|
`dateFormat:scaled`:: These values define the format used to render ordered time-based data. Formatted timestamps must
|
|
adapt to the interval between measurements. Keys are http://en.wikipedia.org/wiki/ISO_8601#Time_intervals[ISO8601 intervals].
|
|
`dateFormat:dow`:: This property defines what day weeks should start on.
|
|
`defaultIndex`:: Default is `null`. This property specifies the default index.
|
|
`defaultColumns`:: Default is `_source`. Defines the columns that appear by default on the Discover page.
|
|
`metaFields`:: An array of fields outside of `_source`. Kibana merges these fields into the document when displaying the
|
|
document.
|
|
`discover:sampleSize`:: The number of rows to show in the Discover table.
|
|
`discover:aggs:terms:size`:: Determines how many terms will be visualized when clicking the "visualize" button, in the field drop downs, in the discover sidebar. The default value is `20`.
|
|
`doc_table:highlight`:: Highlight results in Discover and Saved Searches Dashboard. Highlighting makes request slow when
|
|
working on big documents. Set this property to `false` to disable highlighting.
|
|
`doc_table:highlight:all_fields`:: Improves highlighting by using a separate `highlight_query` that uses `all_fields` mode on
|
|
`query_string` queries. Set to `false` if you are using a `default_field` in your index.
|
|
`courier:maxSegmentCount`:: Kibana splits requests in the Discover app into segments to limit the size of requests sent to
|
|
the Elasticsearch cluster. This setting constrains the length of the segment list. Long segment lists can significantly
|
|
increase request processing time.
|
|
`courier:ignoreFilterIfFieldNotInIndex`:: Set this property to `true` to skip filters that apply to fields that don't exist in a visualization's index. Useful when dashboards consist of visualizations from multiple index patterns.
|
|
`fields:popularLimit`:: This setting governs how many of the top most popular fields are shown.
|
|
`histogram:barTarget`:: When date histograms use the `auto` interval, Kibana attempts to generate this number of bars.
|
|
`histogram:maxBars`:: Date histograms are not generated with more bars than the value of this property, scaling values
|
|
when necessary.
|
|
`visualization:tileMap:maxPrecision`:: The maximum geoHash precision displayed on tile maps: 7 is high, 10 is very high,
|
|
12 is the maximum. {es-ref}search-aggregations-bucket-geohashgrid-aggregation.html#_cell_dimensions_at_the_equator[Explanation of cell dimensions].
|
|
`visualization:tileMap:WMSdefaults`:: Default properties for the WMS map server support in the coordinate map.
|
|
`visualization:colorMapping`:: Maps values to specified colors within visualizations.
|
|
`visualization:loadingDelay`:: Time to wait before dimming visualizations during query.
|
|
`visualization:dimmingOpacity`:: When part of a visualization is highlighted, by hovering over it for example, ths is the opacity applied to the other elements. A higher number means other elements will be less opaque.
|
|
`csv:separator`:: A string that serves as the separator for exported values.
|
|
`csv:quoteValues`:: Set this property to `true` to quote exported values.
|
|
`history:limit`:: In fields that have history, such as query inputs, the value of this property limits how many recent
|
|
values are shown.
|
|
`shortDots:enable`:: Set this property to `true` to shorten long field names in visualizations. For example, instead of `foo.bar.baz`, show `f.b.baz`.
|
|
`truncate:maxHeight`:: This property specifies the maximum height that a cell occupies in a table. A value of 0 disables
|
|
truncation.
|
|
`indexPattern:fieldMapping:lookBack`:: The value of this property sets the number of recent matching patterns to query the
|
|
field mapping for index patterns with names that contain timestamps.
|
|
`indexPattern:placeholder`:: The default placeholder value used when adding a new index pattern to Kibana.
