Hi!
1. It’s because your theme is overriding the placeholder style. Try to increase the CSS compatibility level: Increasing CSS compatibility
Or, you can add a custom CSS rule, which fill force the placeholder size:
[code]
input.orig::-webkit-input-placeholder {
font-size: 14px !important;
}
[/code]
2. That option only affects the woocommerce built in search engine.
If you want to exclude posts/pages/products, then please rather use the Advanded Options -> xclude Posts by ID’s (comma separated post ID-s) option. It’s much safer and faster. Here is a screenshot on how to find your product IDs: https://i.imgur.com/6byLhQf.png
