Price: Now, Searchanise has 6 subscription plans: Free, four subtypes of a PRO plan ($9, $18, $27, and $54), and an Advanced plan, starting from $189.
Pros: A really versatile search solution, that offers much for a reasonable price. It has a full-text relevant search, all-time analytics, built-in synonym dictionaries, autocorrections, and suggestions. In terms of navigation, it has a Smart Navigation system, allowing to show filters in catalogs, customizable filters, a Search Results Widget, and recommendation blocs. Not to mention that it allows it's PRO users to order customizations from the app's dev team. But the best feature, in our opinion, is a big number of integrations, from review apps to multicurrency and multilanguage support. All in all, it allows its users a good amount of versatility, while not being too hard on their wallet.
Cons: Searchanise not always manages to mesh with the color scheme of the store, though it became better at this lately. Search Results Page replaces the default one from the store's theme. It works on simple designs but may cause problems on storefronts with a complex design, so make sure that you can adapt it to your store.
