Example

Main issue:
Set a long search string, then call textModel.findMatches, it will throw the error.

Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `function hello() {
	alert('Hello world!');
}`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "javascript",
	automaticLayout: true,
});

const searchStr = "sdfasefa"; // long string
const textModel = myEditor.getModel();
textModel.findMatches(searchStr, false, false, false, null, true, 100);

Reproduction Steps

const value = /* set from `myEditor.getModel()`: */ `function hello() {
	alert('Hello world!');
}`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "javascript",
	automaticLayout: true,
});

const searchStr = "sdfasefa"; // long string
const textModel = myEditor.getModel();
textModel.findMatches(searchStr, false, false, false, null, true, 100);

Actual (Problematic) Behavior

Throw error due to the search string too long

Expected Behavior

1. What is the size limitation of search string?
2. Is it possible to return matches result 0 with more info instead of throwing an exception directly?

Additional Context

No response

Use the linked Monaco Editor Playground example to reproduce the failure, then inspect the TextModel.findMatches entry point. Confirm that the long search string no longer throws a SyntaxError and verify the behavior against any existing coverage for this path.
