Returns typeahead information for a specified prefix. The maximum number of results returned is based on value you specify for the count argument. The typeahead command can be targeted to an index and restricted by time.


The required syntax is in bold.

| typeahead

Required arguments

Syntax: prefix=<string>
Description: The full search string to return typeahead information.
Syntax: count=<int>
Description: The maximum number of results to return.

Optional arguments

Syntax: collapse=<bool>
Description: Specify whether to collapse a term that is a prefix of another term when the event count is the same.
Default: true
Syntax: endtimeu=<int>
Description: Set the end time to N seconds, measured in UNIX time.
Default: now
Syntax: index=<string>
Description: Search the specified index instead of the default index.
Syntax: max_time=<int>
Description: The maximum time in seconds that the typeahead can run. If max_time=0, there is no limit.
Syntax: starttimeu=<int>
Description: Set the start time to N seconds, measured in UNIX time.
Default: 0
Syntax: use_cache = <boolean>
Description: Specifies whether the typeahead cache will be used if use_cache is not specified in the command line or endpoint. When use_cache is turned on, Splunk software uses cached search results when running typeahead searches, which may have outdated results for a few minutes after you make changes to .conf files. For more information, see Typeahead and .conf file updates.
Default: true or 1


The typeahead command is a generating command and should be the first command in the search. Generating commands use a leading pipe character.

Typeahead and .conf file updates

The typeahead command uses a cache to run fast searches at the expense of accurate results. As a result, sometimes what is in the cache and shows up in typeahead search results may not reflect recent changes to .conf files. This is because it takes 5 or 10 minutes for the cached data to clear, depending on the performance of the server. For example, if you rename a sourcetype in the props.conf file, it may take a few minutes for that change to display in typeahead search results. A typeahead search that is run while the cache is being cleared returns the cached data, which is expected behavior.

If you make a change to a .conf file, you can wait a few minutes for the cache to clear to get the most accurate and up-to-date results from your typeahead search. Alternatively, you can turn off the use_cache argument to clear the cache immediately, which fetches more accurate results, but is a little slower. After you manually clear the cache, you should see the changes to your .conf file reflected in your results when you rerun the typeahead search.

For more information, see Rename source types in the Splunk Cloud Platform Getting Data In manual.

Typeahead and tsidx bucket reduction

typeahead searches over indexes that have undergone tsidx bucket reduction will return incorrect results.

For more information see Reduce tsidx disk usage in Managing indexers and clusters of indexers.


Example 1:

Return typeahead information for sources in the "_internal" index.

| typeahead prefix=source count=10 index=_internal
