[feature]: API for searching issues

[henriquelatorre]

Is there an existing issue for this?

• I have searched the existing issues

Summary

To implement bot like behavior using API it is usually necessary to perform content searching (and filtering), but the current endpoints only allows to get all issues. This gets extremely inefficient for large issue bases and it would be very neat to expose the current search functionality through the public API.

Why should this be worked on?

Implementing an API endpoint for efficient search in large issue bases in Plane would significantly enhance both automation and scalability, allowing bots and external applications to interact seamlessly with project data.
