exclude item without presentation details from search result

Pro Cloud edition of Coveo for Sitecore does not have the filtering/booting rule editor feature. You should instead add the filtering rule programmatically.

With Coveo for Sitecore Hive UI framework: https://docs.coveo.com/en/991/coveo-for-sitecore-v4/filtering-and-ranking-rules-using-javascript

With Coveo for Sitecore Legacy UI framework: https://docs.coveo.com/en/752/coveo-for-sitecore-v4/using-boosting-or-filtering-rules-on-the-search-component-programmatically-using-the-coveo-for-sitecore-legacy-search-ui-framework

To only include indexed items that have a layout (presentation details) in the search results, you have to add a filter like this: `@haslayout=="1"`.

The field is `haslayout`. It might be translated to a Coveo field name like `fhaslayoutYYYYY`. For that, you need to use the `ToCoveoFieldName` server-side method (Legacy UI) or `CoveoForSitecore.Context.fields.toCoveo` JavaScript function (Hive framework).

The field expression operator is `==` for exact match.

The value of the field expression is `"1"` as a string. This is the indexed value for a boolean `true`.

var layout = CoveoForSitecore.Context.fields.toCoveo('@haslayout');

        var contentPathValues = [homePageID, searchPageID];
        expressionBuilder.addFieldNotEqualExpression(fieldName, contentPathValues);
expressionBuilder.addFieldExpression(layout, '==', '1');
        document.getElementById('JSFilterExpression').dataset.scAdvancedFilter = expressionBuilder.build();
    });
