Our Search Syntax is based on a funnel or "pipeline" concept. The wide mouth of the funnel begins with all your current Sumo Logic data, and you narrow the funnel by entering keywords and operators separated by pipes ("|"). Each operator acts on the results from the previous operator so that you can progressively filter and pinpoint your search until you find exactly what you’re looking for.
In the Search tab, a search query is typically formatted something like this:
keyword search | parse | where | group-by | sort | limit
Let's start with a basic search:
- Click + in the tab bar and select Log Search.
- Enter a simple key term like "error" in the search field, or type an asterisk wildcard (*) to find all messages.
- Hit Enter or click Start.
- Sumo Logic returns all the log entries containing the search term in the Messages tab below the histogram.
Now let's take a look at a slightly more complex search query to see how queries are formed.
All queries begin with a keyword or string search. Wildcards are allowed including an asterisk (*) for zero or more characters and a question mark (?) for a single character. Strings can be parsed based on start and stop anchor points in messages, and then aliased as user-created fields. All operators are separated by the pipe symbol (|).
Here's an example:
_sourcecategory=apache | parse "* --" as src_ip | count by src_ip | sort _count
Broken up, this means:
As queries get longer and more complex, it is a best practice to format your queries by using a soft return before the pipes, such as:
| parse "* --" as src_ip
| count by src_ip
| sort _count
This method lines up the pipes and makes your query much easier to read.

- Save a search to re-use later or to run as regularly scheduled searches that can be delivered to your email address.
- Share a link to the results of a search query, depending on each user's permissions. To share a link to a search, after your query has run, click Share beneath the search query box. This link will be available for three years after it is created.
