As discussed in the live chat that you can increase its width by adding the below CSS code in the Custom CSS option of Ivory Search plugin settings on the path Ivory Search -> Settings -> Settings

.k2t-menu li form.is-search-form {
 width: 1000px;
 max-width: 100%;
}

.k2t-menu li form.is-search-form label {
 width: 68%;
 display: inline-block;
 vertical-align: sub;
}

.k2t-menu li form.is-search-form label input.is-search-input {
 width: 100%;
}
