Coding Query Pipeline Language Rules

Coveo Cloud organization members with developer skills can use the Query Pipeline Language (QPL) syntax to create more flexible query pipeline rules.

To code query pipeline language rules

1. Ensure that you log in to the Coveo Platform as a member of a group with the required privileges to manage query pipeline components in the target Coveo Cloud organization, if not already done.

2. In the main menu on the left, under Search, select Query Pipelines.

3. On the Query Pipelines page, click the query pipeline for which you want to code rules, and then in the Action bar, click Edit Components.

4. On the selected pipeline page, select the tab for the type of rule that you want to code.

5. On the selected component subpage, click Add rule, and then select <QPL_COMPONENT> with code.

6. In the Add a Rule With Code dialog:

   

   1. Enter a rule respecting the query pipeline language syntax [see Query Pipeline Language (QPL)].

   2. Click Add Rule.

   If you try to use this interface to extend the Coveo Cloud query pipeline behavior (e.g., by entering JavaScript code), you’ll receive an error message:

   The definition of the statement is syntactically invalid.

7. You can perform other actions on your rule (see Adding and Managing Query Pipeline Rules and Rule Conditions From Tabs).

8. Validate that your new rule performs as desired (see Testing Query Pipeline Changes or Testing Coveo Machine Learning Models).
