The Top 9 E-commerce Search Solutions for Optimized Discovery

Your customers can’t buy what they can’t find.

The right e-commerce search solution helps them discover products faster, improving the search experience and boosting conversions across your store.

But many site search solutions still rely on outdated technology. They struggle with natural language, ignore user intent, and surface irrelevant results – especially for mobile users. Even worse, some still show out-of-stock products, leading to dead ends and frustration when shoppers are ready to buy but simply can’t.

In this guide, we’ll break down what to look for in the best e-commerce site search solutions, what to avoid, and which platforms actually deliver.

TL;DR

• The best e-commerce search solutions drive product discovery, improve the search experience, and increase customer satisfaction
• Prioritize platforms with AI-powered search, natural language processing, autocomplete suggestions, and multilingual e-commerce search capabilities
• Voyado offers real-time personalization, predictive search, and search analytics built in, no integrations or developer setup needed
• This guide compares top options to help you choose the right AI e-commerce search solution for retailers and growing brands.

Let’s start with why search matters more than ever and what’s holding many brands back.

Why optimized e-commerce search is essential for modern brands

Search is often the first thing your customers interact with. It’s where user intent meets action, and it needs to deliver. If the search function isn’t fast, relevant, and easy to scan, shoppers will bounce.

Modern shoppers expect more than basic keyword matching. They want:

• Smart suggestions
• Typo tolerance
• Fast, mobile-friendly results
• Search that feels tailored to their intent

But many e-commerce search engines still fall short. They miss context, struggle with complex search queries, and show irrelevant search results. That leads to frustrated users, fewer conversions, and lost revenue.

Your team may also be stuck with tools that lack:

• Faceted search
• Search analytics
• Multilingual capabilities
• AI-powered personalization

Without these features, improving your e-commerce site search solution becomes a constant uphill battle.

But what does a strong solution actually look like? Let’s break down the key features that make the biggest difference.

5 key features of advanced e-commerce search solutions

Not all e-commerce site search solutions are created equal. If you want to drive more conversions, support your team, and deliver a smoother site search experience, these are the features to look for.

1. AI-powered relevance and personalization

Modern e-commerce search solutions use machine learning to surface the most relevant products for each shopper. Results adapt in real time based on clicks, purchase history, and user behavior.

2. Multilingual and typo-tolerant capabilities

Your customers do not all search the same way. The best e-commerce search solutions support multiple languages, regional differences, and even misspelled search terms. This increases the chances of showing accurate results to more people, faster.

3. Natural language processing (NLP)

Natural language processing helps your internal search engine understand meaning, not just keywords. It improves how your site handles long-tail search queries and conversational inputs, leading to more relevant results.

4. Intelligent filtering and faceted search

Faceted search enables users to filter results by size, color, price, and other criteria. Combined with intelligent filters, it simplifies complex search experiences and helps shoppers find what they want quickly.

5. Visual and voice search options

Shoppers now expect more than just a search bar. Visual search lets them upload images to find similar products, while voice search gives mobile users and accessibility-focused shoppers a faster way to interact.

These advanced features do more than improve UX. They increase customer satisfaction, support better product discovery, and help your team deliver more personalized journeys.

Next, let’s look at how brands are putting these capabilities into practice with smarter search strategies.

6 strategic approaches to e-commerce search solutions

Strong features are just the start. To truly stand out, your team needs a search strategy that supports product discovery, increases conversions, and keeps customers coming back.

Here’s how we approach advanced e-commerce search solutions with AI that are built to scale:

1. AI-powered personalization

Search should adapt to each shopper in real time. That means learning from clicks, search terms, and behavior to show the right products at the right moment.

Voyado’s site search for retailers delivers dynamic, personalized results without extra configuration.

It is built to:

• Understand behavior
• Improve over time
• Guide shoppers toward conversion using advanced machine learning and a real-time search algorithm

2. NLP and conversational search

Customers do not always type perfect keywords. They ask full questions, use different terms, or include filters right in their query.

That is where natural language processing comes in. It helps your search engine interpret what people actually mean.

Voyado uses advanced NLP to:

• Handle complex and conversational search queries
• Return more relevant results
• Improve customer satisfaction with every interaction

3. Multilingual search optimization

If your e-commerce website serves multiple markets, your search engine needs to speak their language. And not just translate, but optimize for local behavior and search intent.

Voyado’s multilingual e-commerce search solution supports:

• Accurate search results across multiple languages
• Local nuance based on region-specific behavior
• Seamless scaling for international catalogs

It’s one of the most flexible multilingual e-commerce search solutions available.

It also supports both B2C and B2B e-commerce site search solutions for international growth.

4. Predictive and contextual search

Great search does not just respond.

It predicts by analyzing:

• Past behavior
• Purchase history
• Real-time browsing signals

Voyado’s predictive search capabilities are built in, allowing your team to serve personalized, intent-driven results that improve the overall e-commerce site search experience.

5. Visual and interactive search experiences

Search is no longer limited to a bar. Today’s tools offer visual search, voice search, and other rich experiences that make discovery easier and more engaging.

Voyado supports interactive options that let users:

• Search with images
• Filter results more intuitively
• Navigate discovery journeys that feel fully personalized

These features are especially useful for mobile users and improve accessibility across your e-commerce site.

6. Analytics and continuous optimization

To improve search, you need to understand it.

Look for search solutions with built-in analytics that help you:

• Track what shoppers are searching for
• Understand how they interact with search results
• Spot drop-off points in the journey

This kind of search data is essential for improving performance over time.

How Dustin increased conversions by 10%

Dustin, a leading B2B reseller of IT products in the Nordics, had invested heavily in digital infrastructure, but relevance in their e-commerce site search still wasn’t where it needed to be.

Their team used manual rules to emphasize things like stock levels and campaigns, but those same rules were starting to suppress new products and deliver inconsistent results.

As Jens Malmqvist, Store Optimisation Manager at Dustin, put it:

“We started out by guessing what is important for our customers, which clearly didn’t work.”

What changed with Voyado:

• Ran an A/B test comparing manual rules vs. AI-powered search
• Let Voyado’s e-commerce search solution fully control relevance
• Saw a conversion lift of over 10%
• Delivered faster, more relevant results based on real-time customer behavior

How NetOnNet doubled conversion rates

NetOnNet, one of Sweden’s largest electronics retailers, knew something was missing from their e-commerce strategy.

When the CEO asked, “Who are our customers?” and no one had an answer, they realized it was time to rethink their approach to data, personalization, and on-site engagement.

Disconnected systems and general promotions meant they were sending the same messages to everyone, with little insight into what individual shoppers actually wanted.

What changed with Voyado:

• Integrated customer data across e-commerce and POS systems
• Created customer profiles and lifestyle segments using Bisnode enrichment
• Built personalized journeys and product recommendations with automation
• Improved click-through rate by 100%, doubled conversions, and increased average order value by 44%

“Voyado gives us the ability to quickly act on customer insights and successfully create great customer experiences.” –  Pär Gancarz, CRM Manager at NetOnNet

How NELLY scaled real-time personalization

As a fast-growing Nordic fashion brand, NELLY knew that disconnected systems were holding them back. Their customer data, communications, and product recommendations were spread across three separate platforms.

This made it difficult to respond to customer behavior in real time- and even harder to scale.

So when NELLY migrated to a new e-commerce platform in 2024, they saw a chance to rethink everything. Personalized journeys, real-time automation, and better efficiency were no longer just goals; they were requirements.

What changed with Voyado:

• Consolidated CRM, automation, and product discovery in a single solution
• Streamlined workflows like abandoned cart and browse journeys
• Delivered real-time product recommendations tailored to customer behavior
• Improved efficiency and engagement across the entire customer journey

“Implementing Voyado has simplified the process for NELLY to create even more relevant customer journeys.” – Therese Leike Kärvestedt, Product Owner CRM at Omniarch/NELLY
