`query:allowLeadingWildcards`:: When set, * is allowed as the first character in a query clause. Currently only applies when experimental query features are enabled in the query bar. To disallow leading wildcards in basic lucene queries, use query:queryString:options.
`search:queryLanguage`:: Default is `lucene`. Query language used by the query bar. Choose between the lucene query syntax and kuery, an experimental new language built specifically for Kibana.
`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`.
`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.
`courier:maxConcurrentShardRequests`:: Controls the {ref}/search-multi-search.html[max_concurrent_shard_requests] setting used for _msearch requests sent by Kibana. Set to 0 to disable this config and use the Elasticsearch default.
`visualize:enableLabs`:: Enables experimental visualizations. Default is `true`. If this is turned off, users will not be able to create visualizations that are considered experimental. They will also not be able to add or view these visualizations on a dashboard.
`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.
`timepicker:quickRanges`:: The list of ranges to show in the Quick section of the time picker. This should be an array of objects, with each object containing `from`, `to` (see {ref}/common-options.html#date-math[accepted formats]), `display` (the title to be displayed), and `section` (which column to put the option in).
`notifications:lifetime:banner`:: Specifies the duration in milliseconds for banner notification displays. The default value is 3000000. Set this field to `Infinity` to disable banner notifications.
`notifications:lifetime:error`:: Specifies the duration in milliseconds for error notification displays. The default value is 300000. Set this field to `Infinity` to disable error notifications.
`notifications:lifetime:warning`:: Specifies the duration in milliseconds for warning notification displays. The default value is 10000. Set this field to `Infinity` to disable warning notifications.
`notifications:lifetime:info`:: Specifies the duration in milliseconds for information notification displays. The default value is 5000. Set this field to `Infinity` to disable information notifications.
`metrics:max_buckets`:: The maximum numbers of buckets that cannot be exceeded. For example, this can arise when the user selects a short interval like (e.g. 1s) for a long time period (e.g. 1 year)
`state:storeInSessionStorage`:: [experimental] Kibana tracks UI state in the URL, which can lead to problems when there is a lot of information there and the URL gets very long. Enabling this will store parts of the state in your browser session instead, to keep the URL shorter.
`context:defaultSize`:: Specifies the initial number of surrounding entries to display in the context view. The default value is 5.
`context:step`:: Specifies the number to increment or decrement the context size by when using the buttons in the context view. The default value is 5.
`context:tieBreakerFields`:: A comma-separated list of fields to use for tiebreaking between documents that have the same timestamp value. From this list the first field that is present and sortable in the current index pattern is used.
