How to set required false for property in Stored Search in DocClass

We have some properties defined in Stored Search Class which are required in Stored Search CLass level

In ICN, it is not allowing us to save the search template, as few properties are required.

How can we make these properties required = false and it should allow to save the search template.

How can we achive this using ICN plugin?

What are using as a repository, I am assuming FileNet from what you have written. In which case you would need to go into ACCE (the administration tool for Content Platform Engine) and remove the required flag from the various properties. Note that it seems a little odd that there are required properties at the Stored Search Class level.
