Thanks for your response – I can replicate your test, but the secondary result is second last out of all the other pages on my site. There are other far less relevant responses appearing above.

Ordering the search results is a different thing that you can configure as described below.

Removing the synonym from the backend does not change the return of the desired page, indicating that synonyms still aren’t working… I’m confused because a couple of weeks ago it was functioning so well! I don’t want to be a pain, but is there anything else to try?

This can be due to the cache.

Could you please give me one single example of the words from your website where the synonym is not working?

I tested it on your shared website and got search results for both keywords as shown in the attached screenshots.

Please advise.

You are always welcome, I’m glad I was able to help you with this matter. There is no obligation but by your kind words I wonder if I could trouble you to leave a review based on this experience here:

I’d really appreciate that. 🙂

And if I can be of any further assistance please don’t hesitate to ask.

Please remove the CSS code that you have put and use the below CSS code.

@media (min-width: 1240px){
    #header li.is-menu {
        float: right;
        margin-top: 28px;
    }
    #header .header div.header-left {
        display: block;
    }
    #header div.header {
        display: block;
    }
}

It appears there on your website as shown in the attached screenshot.

Please advise.
