* Add query enhancements opt-in switch to query bar (#17232) Makes our language updates more visible to users and removes mentions of Kuery as a separate language. Users still get the old lucene experience by default, but have the option to opt-in to "experimental query features" directly in the query bar. Goal is to get more feedback by making these new features more prominent and less of a jump from lucene. * fix test

== Searching Your Data
|
|
You can search the indices that match the current index pattern by entering
|
|
your search criteria in the Query bar. You can use Kibana's standard query language
|
|
(based on Lucene https://lucene.apache.org/core/2_9_4/queryparsersyntax.html[query syntax])
|
|
or the full JSON-based {ref}/query-dsl.html[Elasticsearch Query DSL]. Autocomplete
|
|
and a simplified query syntax are available for the Kibana query language as experimental
|
|
features which you can opt-in to under the options menu in the Query Bar.
|
|
|
|
When you submit a search request, the histogram, Documents table, and Fields
|
|
list are updated to reflect the search results. The total number of hits
|
|
(matching documents) is shown in the toolbar. The Documents table shows the
|
|
first five hundred hits. By default, the hits are listed in reverse
|
|
chronological order, with the newest documents shown first. You can reverse
|
|
the sort order by clicking the Time column header. You can also sort the table
|
|
by the values in any indexed field. For more information, see <<sorting,
|
|
Sorting the Documents Table>>.
|
|
|
|
To search your data, enter your search criteria in the Query bar and
|
|
press *Enter* or click *Search* image:images/search-button.jpg[] to submit
|
|
the request to Elasticsearch.
|
|
|
|
[NOTE]
|
|
===========
|
|
You can opt-in to our experimental query features by default by changing `search:queryLanguage`
|
|
to `kuery` under Advanced Settings.

=== Lucene Query Syntax
|
|
Kibana's query language has historically been based on the Lucene query syntax. The following
|
|
are some tips that can help get you started.
|
|
|
|
* To perform a free text search, simply enter a text string. For example, if
|
|
you're searching web server logs, you could enter `safari` to search all
|
|
fields for the term `safari`.
|
|
|
|
* To search for a value in a specific field, prefix the value with the name
|
|
of the field. For example, you could enter `status:200` to find all of
|
|
the entries that contain the value `200` in the `status` field.
|
|
|
|
* To search for a range of values, you can use the bracketed range syntax,
|
|
`[START_VALUE TO END_VALUE]`. For example, to find entries that have 4xx
|
|
status codes, you could enter `status:[400 TO 499]`.
|
|
|
|
* To specify more complex search criteria, you can use the Boolean operators
|
|
`AND`, `OR`, and `NOT`. For example, to find entries that have 4xx status
|
|
codes and have an extension of `php` or `html`, you could enter `status:[400 TO
|
|
499] AND (extension:php OR extension:html)`.
|
|
|
|
For more detailed information about the Lucene query syntax, see the
|
|
{ref}/query-dsl-query-string-query.html#query-string-syntax[Query String Query]
|
|
docs.
|
|
|
|
NOTE: These examples use the Lucene query syntax. When lucene is selected as your
|
|
query language you can also submit queries using the {ref}/query-dsl.html[Elasticsearch Query DSL].

|
|
=== Saving and Opening Searches
|
|
Saving searches enables you to reload them into Discover and use them as the basis
|
|
for <<visualize, visualizations>>. Saving a search saves both the search query string
|
|
and the currently selected index pattern.
|
|
|
|
==== Saving a Search
|
|
To save the current search:
|
|
|
|
. Click *Save* in the Kibana toolbar.
|
|
. Enter a name for the search and click *Save*.
|
|
|
|
You can import, export and delete saved searches from *Management/Kibana/Saved Objects*.
|
|
|
|
==== Opening a Saved Search
|
|
To load a saved search into Discover:
|
|
|
|
. Click *Open* in the Kibana toolbar.
|
|
. Select the search you want to open.
|
|
|
|
If the saved search is associated with a different index pattern than is currently
|
|
selected, opening the saved search changes the selected index pattern. The query language
|
|
used for the saved search will also be automatically selected.
|
|
|
|
|
|
[[select-pattern]]
|
|
=== Changing Which Indices You're Searching
|
|
When you submit a search request, the indices that match the currently-selected
|
|
index pattern are searched. The current index pattern is shown below the toolbar.
|
|
To change which indices you are searching, click the index pattern and select a
|
|
different index pattern.
|
|
|
|
For more information about index patterns, see <<settings-create-pattern,
|
|
Creating an Index Pattern>>.

|
[[autorefresh]]
|
|
=== Refreshing the Search Results
|
|
As more documents are added to the indices you're searching, the search results
|
|
shown in Discover and used to display visualizations get stale. You can
|
|
configure a refresh interval to periodically resubmit your searches to
|
|
retrieve the latest results.
|
|
|
|
To enable auto refresh:
|
|
|
|
. Click the *Time Picker* image:images/time-picker.jpg[Time Picker] in the
|
|
Kibana toolbar.
|
|
. Click *Auto refresh*.
|
|
. Choose a refresh interval from the list.
|
|
+
|
|
image::images/autorefresh-intervals.png[]
|
|
|
|
When auto refresh is enabled, the refresh interval is displayed next to the
|
|
Time Picker, along with a Pause button. To temporarily disable auto refresh,
|
|
click *Pause*.
|
|
|
|
NOTE: If auto refresh is not enabled, you can manually refresh visualizations
|
|
by clicking *Refresh*.
