Shopify Search & Discovery vs Searchanise vs Boost: Which Search App in 2026

Shopify's on-site search is a known weak spot, and three answers dominate the fix: the free native Search & Discovery app, Searchanise, and Boost. They solve the same surface problem (shoppers cannot find products) with very different pricing models and very different ceilings. Facts checked June 17, 2026, against each app's Shopify App Store listing and pricing page. We do not make a search app and have no referral relationship with any of these.

One thing to clear up first, because it is a common mix-up: a search app helps people who are already on your site find products. It does not affect whether an AI shopping agent recommends you, because agents read your Product structured data, not your search bar. Different job, different tool. This comparison is about on-site discovery for human shoppers.

The short version

• Shopify Search & Discovery (3.1 stars, 466 reviews) is free and built in: filters, synonym groups, product boosts, related and complementary recommendations, plus a search analytics dashboard. It is the right starting point for small catalogs, with the caveat that its relevance is basic and recent reviews cite real matching problems.
• Searchanise Search & Filter (4.8 stars, 1,213 reviews) is the value pick: a genuinely usable free plan, then $19 to $49 a month priced by catalog size, not revenue. AI personalization, advanced filters, and merchandising are included even on the free tier per its listing.
• Boost AI Search & Filter (4.7 stars, 1,582 reviews) is the enterprise pick: deep custom filter trees, AI-personalized search and recommendations, in-collection search, and heavy merchandising campaigns. Priced by store GMV, from $29 a month up into the hundreds.

The pricing models are the real decision

This is not a feature fight first. It is a pricing-model fight, because Searchanise and Boost charge on different axes:

Searchanise bills on catalog size. Your monthly cost is set by how many products you have, not how much you sell. A high-revenue store with a tight catalog pays little.

Boost bills on GMV. Each tier has a base price that scales with your monthly online revenue, so a high-traffic store on the Launch plan can climb from $29 toward $159 before it even reaches the next tier's features.

The native app bills on neither. It is free, and the trade is relevance and depth.

What each one actually does

• Relevance and matching. Boost and Searchanise both ship AI/semantic search that handles synonyms, typos, and natural phrasing. The native app advertises AI search and typo tolerance, but recent reviewers (June 2026) report it effectively matching only product titles and breaking on SKU, barcode, and vendor queries. That gap is the single biggest reason stores outgrow it.
• Filters. All three do faceted filtering. Boost's custom filter trees go deepest (5 on Launch, unlimited on Accelerate) and are its signature. Searchanise includes advanced filters across its tiers. The native app does multi-category filters and is fine for straightforward catalogs.
• Merchandising. Boost leads here with merchandising campaigns (10 on Launch, 40 on Convert) and visual rule-building. Searchanise includes merchandising in its plans. The native app offers product boosts, which is a lighter version of the same idea.
• Recommendations. Native ships related and complementary product blocks for free. Boost adds AI-personalized recommendations and predictive bundling on higher tiers; Searchanise includes AI personalization per its listing. If recommendations are your priority, also weigh dedicated upsell apps from the best Shopify upsell apps roundup, which go further than any search app.
• In-collection search. Boost adds search within a collection on Convert and up, useful for very large catalogs where a collection alone returns hundreds of items. Worth noting if you have struggled with filtering large collection pages.

The reported complaints

Phrased as reported, from each listing's recent critical reviews:

• Native Search & Discovery: the 3.1 rating is the headline. June 2026 reviews describe search "only searches product title" and broken results when searching by keyword, SKU, barcode, or vendor. For a store where search drives real revenue, those are not edge cases.
• Searchanise: complaints are structurally scarce against 1,213 reviews; the recurring critical note is occasional sync lag on very large catalogs and tier limits that can surprise stores near a product-count threshold.
• Boost: the main friction in critical reviews is cost climbing with GMV, and the jump from Launch to Convert ($29 to $299) being steep for stores that need one Convert-only feature.

Decision rules

1. Small catalog, testing whether search even matters: start with the free native app. If shoppers can find things and your search analytics look healthy, you are done. Spend nothing.
2. Real revenue, modest catalog, value-minded: Searchanise. Its catalog-size pricing means a high-revenue store with a focused product range pays $19 to $49 while getting AI search and merchandising.
3. Large catalog, search-and-merchandising as a growth lever: Boost. The custom filter trees, in-collection search, and merchandising campaigns are the deepest of the three, and GMV pricing is fair if search genuinely moves your numbers.
4. Shopify Plus with a tight catalog: Searchanise's $49 Plus tier is the value play; Boost is the choice only if you need its merchandising depth and can absorb the GMV-scaled cost.

Whichever you pick, remember the boundary: these apps win you the shopper who is already on your site. Getting found in the first place, by humans on Google and by AI shopping agents, is a separate problem that runs on your structured data.
