Queries in LogScale are written and can be reused from the Search tab of the User Interface.
Writing a New Query
To write a new query in LogScale:
Go to Repositories and Views page and click on the Repository or View in which you want to search.
Type one or more search terms in the Search box and click or enter.
If needed, adjust the size of the box by dragging manually or clicking the arrows on the right to make it fit the query.
Here is an example of very simple search with just one value:
Figure 72. One-Value Search
The Search box contains a query, and the search results appear in the Event list below.
In the example, we are filtering by selecting only events that contain
example.com anywhere in their log
This is essentially the same as using grep on the Unix command-line, except with LogScale User Interface you can do it across all the logs, and from all servers and services at once.
Taking this example a little further, when we add a second search term
to display only results for
proxyRequest, the results are

For much more details on the possible operations you can perform with queries, see Common Queries.
You can save a query for future use — you save the query, not the resulting data.
Click on thepull-down menu at the top right above the main panel.
Specify in the Save Query window popping up whether this query is overwriting an existing one.
Give the query a name and click.
You can find again and reload saved queries anytime later from thepull-down menu at the top of the User Interface, just above the query input field. You can make a saved search load automatically when opening the repository.

Clickingon any saved query allows you to mark that query as favorite, export it as YAML, edit or delete it.
You can also save a query you use often by creating your own syntax function — see User Functions (Saved Searches) for more information.
You can recall recently run queries or saved queries from thepull-down menu of the User Interface:

Using Saved Queries in Interactions
You can use saved queries to save interactions on the Search page, thus avoiding recreation of the same interaction at every search. For more information on the interactions we support, see Event List Interactions and Managing Dashboard Interactions.
You can either:
Load a saved query with interaction from→ (or pick a saved query from a package):
Figure 76. Loading a Saved Query
Make an interaction from a query you've created and save it in a new saved query — or save your interaction in an existing saved query. From the Results tab click → and get the Save query dialog, where you save your query along with the interaction you have created.
