Logs Search Query Syntax

When searching for logs, you can create queries using a subset of Lucene query syntax to refine your search.

The query string is parsed into a series of terms and operators:

  • A term can be a single word such as jane or smith.
  • A term can be a phrase surrounded by double quotes ("customer log"), which will match all words in the phrase in the same order.
  • A term without a field name will only match these selected fields fields.
  • Multiple terms can be grouped together with parentheses to form sub-queries.
  • All search fields are case sensitive.
  • Operators (AND, OR, NOT) work on all searchable fields.

Searchable fields

The following list of fields are searchable and case sensitive:

  • log_id: the id of the log event
  • date: The moment when the event occured.
  • connection: The connection name related to the event.
  • connection_id: The connection id related to the event.
  • client_id: The client id related to the event
  • client_name: The name of the client related to the event.
  • ip: The IP address from where the request that caused the log entry originated.
  • user_id: The user id related to the event.
  • user_name: The user name related to the event.
  • description: The description of the event.
  • user_agent: The user agent that is related to the event.
  • type: One of the possible event types.
  • strategy: The connection strategy related to the event.
  • strategy_type: The connection strategy type related to the event.
  • hostname: the hostname that is being used for the authentication flow.

Fields searchable against bare terms

If a search term is entered without a field name, it will only be searched against the following fields:

  • user_name
  • connection
  • client_name
  • type
  • ip
  • log_id
  • description

Exact matching

To find exact matches, use double quotes: description:"Username invalid".

For example, to find logs with the description Username invalid, use q=description:"Username invalid":

Wildcards

Wildcard searches can be run on terms using the asterisk character (*) to replace zero or more characters: user_name:john*. They can be used for prefix matching, for example user_name:j*. For other uses of wildcards (e.g. suffix matching), literals must have 3 characters or more. For example, name:*usa is allowed, but name:*sa is not.

The question mark character (?), is currently not supported.

For example, to find all logs for users whose usernames start with john, use q=user_name:john*:

Ranges

You can use ranges in your log search queries. For inclusive ranges use square brackets: [min TO max], and for exclusive ranges use curly brackets: {min TO max}.

Curly and square brackets can be combined in the same range expression. You can also use wildcards within ranges.

As an example, to find all logs from December 18, 2018 until the present, use q=date:[2018-12-18 TO *]. If you'd like to search logs from the beginning of your retention period until, but not including, December 19, 2018, use q=date:[* TO 2018-12-19}.

Example queries

Below are some examples to show the kinds of queries you can make with the Management API.

Use Case Query
Search all logs with connections that contains "Pass" connection:*pass*
Search all logs for users with a user name that contains "fred" user_name:*fred*
Search all logs with user id's matching exactly "123" user_id:"123"
Search for all logs with a type starting with "s" type:s*
Search for user names that start with "jane" and end with "smith" user_name:jane*smith
Search for all logs in December 2018 date:[2018-12 TO 2018-01-01}
Search for all logs from December 10, 2018 forward date:[2018-12-10 TO *]
Search for all logs from January 1, 2019 at 1AM, until, but not including January 1, 2019 at 12:23:45 date:[2019-01-01T01:00:00 TO 2019-01-01T12:23:45}

Limitations

When you query for logs with the list or search logs endpoint, you can retrieve a maximium of 100 logs per request. Additionally, you may only paginate through up to 1,000 search results. If would like to receive more logs, please retrieve your logs by checkpoint retrieval.

If you get the error 414 Request-URI Too Large this means that your query string is larger than the supported length. In this case, refine your search.

Search engine migration

We are currently migrating our logs search engine to provide customers with the most scalable, robust and fastest search experience. All tenants in the cloud US region were migrated to the latest engine (v3) starting November 15, 2018. Tenants in other cloud regions are still on the previous engine (v2) and will be migrated soon. Tenants whose search queries are incompatible with v3 will be notified.

Search engine v3 breaking changes

When calling the GET /api/v2/logs or GET /api/v2/users/{user_id}/logs endpoints using the include_totals parameter, the result is a JSON object containing a summary of the results and the requested logs. The JSON object looks something like:

When searching for logs using search engine v2, the totals field in your results tells you the number of logs that match the query you provided. However, in v3, the totals field tells you how many logs are returned in the page (similar to what the length field returns). If your application relies on the totals field for pagination purposes, please update your logic to handle this change appropriately.

Query Syntax

While the query syntax described in this article is compliant with both the old and new engines, there are some special queries that behave different in v2 and v3:

  • Log fields are not tokenized like in v2, so description:rule will not match a description with value Create a rule nor Update a rule like in v2. Instead, use description:*rule. See wildcards and exact matching.
  • The .raw field extension is no longer supported and must be removed. In v3, fields match the whole value that is provided and are not tokenized as they were in v2 without the .raw suffix.
  • To search for a specific value nested in the details field, use the path to the field (i.e., details.request.channel:"https://manage.auth0.com/"). Bare searches like details:"https://manage.auth0.com/" do not work.
