It seems I didn’t explain it clearly to you, therefore, you didn’t understand it.

Let me explain to you again, the AND condition is only considered for one tag and not on multiple tags that you are considering.

There are 2 tags on the post, one ‘ivory’ and one ‘search’.
If you search ‘ivory search’ or ‘search ivory’ it doesn’t find it.

In this case, there isn’t any tag containing both the words ‘ivory search’ or ‘search ivory’ on your website therefore it doesn’t return anything. As said above it doesn’t consider multiple tags.

You can achieve this by adding the below CSS code in the Custom CSS option of Ivory Search plugin settings on the path Ivory Search -> Settings -> Settings

form.is-search-form {
    width: 100%;
    display: table;
    margin: 0 auto;
}

form.is-search-form label {
    width: calc( 100% - 100px );
}

form.is-search-form label input.is-search-input {
    width: 100%;
}

Please change the above-shared CSS code according to your requirement.

I hope you are well today and thank you for your question.

Could you please share the page URL from your site where it is displaying so that I can help you to achieve it?

Best regards,
