public bool validateFilters;

Description

Boolean indicating if filters should be validated. Default is false.

If true and skipUnknownFilters is false, unknown filters will generate errors if no default handler is provided with QueryEngine.SetDefaultFilter.

using UnityEditor.Search;

    [MenuItem("Examples/QueryValidationOptions/validateFilters")]

        // Set up the query validation options with no filter validation
        var validationOptions = new QueryValidationOptions { validateFilters = false };

        // Set up the query engine
        var queryEngine = new QueryEngine<MyObjectType>(validationOptions);
        queryEngine.AddFilter("id", myObj => myObj.id);
        queryEngine.SetSearchDataCallback(myObj => new[] { myObj.id.ToString(), myObj.name });

        // Parse a query with the filter "id". There shouldn't be any errors
        var query = queryEngine.Parse("id>10");
        Debug.Assert(query.valid, $"Query \"{query.text}\" should be valid.");

        // Because the QueryEngine doesn't validate filters, no other filters will generate an error when parsed.
        query = queryEngine.Parse("name:MyName");
        Debug.Assert(query.valid, $"Query \"{query.text}\" should be valid.");
