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

PD: I have activated in Include > Taxonomy Terms, the taxonomies that I want available to search, making ON the option “OR – Search posts having any one of the above selected terms.” and these options “Search in taxonomy terms title.” “Search in taxonomy terms description.”

From your above description it seems you have configured the search form correctly to search posts by category name and it should work on your site.

Could you please share me screenshot of search form settings that you have configured and also share me your site URL where the search form displaying so that I can troubleshoot it?

Is the edit feature time limited? I cannot see the edit buttons. I would like to go back and remove my URL from my previous posts

Yes it is limited. I have removed your site URL from your reply.

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

PS: Wish this forum had an edit button!

Yes there is an edit button as shown in the attached screenshot to edit the reply but it is only available for limited perios of time after posting reply so that the feature won’t be misused by users.

1) How can I place a genericon above the “Search” text (like the search link on the far left), so it fits in with the rest of the nav bar.

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

.nav-secondary .genesis-nav-menu > .is-menu > a:before {
    content: "\f400";
}
.nav-secondary .is-menu a:before {
    display: block;
    vertical-align: top;
    text-align: center;
    -moz-transition: color .1s ease-in 0;
    -webkit-transition: color .1s ease-in 0;
    font-family: "Genericons";
    font-size: 36px;
    font-size: 3.6rem;
    font-style: normal;
    font-weight: normal;
    font-variant: normal;
    line-height: 1;
    margin-bottom: 8px;
    text-decoration: inherit;
    text-transform: none;
    -moz-osx-font-smoothing: grayscale;
    -webkit-font-smoothing: antialiased;
    width: 100%;
    speak: none;
}

2) How can I move this menu item to be on the far left, to replace the existing search link.

Please use below custom CSS code to display it to the left side of menu.

.nav-secondary li.is-menu {
    float: left;
}

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

For some reason I have a search box in the middle of my menu as well as a magnifying glass at the right side. I would like to get rid of the one in the middle if possible – how can I do this?

I visited your shared site but didn’t see any search form in the middle of me as shown in the attached screenshot.

Please advise.

I also want to get rid of the “Search” button that drops down below the actual white search box because I think it’s redundant. Is that possible to do as well?

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

.is-menu input.search-submit {
    display: none;
}
