PrestaShop's native search
is not enough

PrestaShop includes a basic search, but its limitations become quickly visible as your catalog grows.

No typo tolerance

Native search can't find products when the user makes a typo. "trousers" vs "trousrs": empty result.

No semantic understanding

Exact keyword matching ignores synonyms and variations. "sports shoes" won't find "running trainers".

No merchandising control

The Stats section lists top searches, but you can't promote a product on a given query, nor act on failed searches beyond rewriting product titles.

How PrestaShop store search
actually works

Knowing what the built-in engine does, and where it stops, tells you whether tuning it is enough or whether you need to replace it.

PrestaShop does not query your product tables directly when a visitor searches. It maintains its own index in the ps_search_word and ps_search_index tables, built by splitting product fields into words. That index is rebuilt from Shop Parameters > Search, either fully or by adding only the missing products, and it needs to be refreshed after a catalog import.

Three settings drive the results your customers see:

  • Field weights. Product name, reference, short description, description, tags, category and brand each carry a weight. Raising the weight of the product name is usually the single most effective adjustment.
  • Fuzzy search. An approximation setting that lets a query match a word that is close but not identical. It helps with typos, and it costs query time, which is why it is often turned off on large catalogs.
  • Aliases. A manual mapping from one typed word to one indexed word. This is the built-in answer to vocabulary gaps, maintained by hand, one entry at a time.

The Stats section also includes a best searches report listing the terms visitors typed and how many results each returned. It is enough to spot the worst offenders, not to act on them at scale.

Where it stops

The engine matches words. It has no notion of what a product is, so "waterproof jacket" and "rain coat" remain unrelated unless someone writes the alias. It never learns: the ranking on day one is the ranking a year later, whatever your customers clicked or bought in between. And it runs on the same MySQL database as the rest of the store, so a traffic spike degrades browsing and search at the same time.

Three ways to improve PrestaShop search

1. Tune the native engine

Adjust field weights, add aliases, enable fuzzy search, rebuild the index. Free, done in an afternoon, and worth doing before anything else. The ceiling is low: still no semantics, no learning, no merchandising.

2. Install a search module

A module replaces the native search from inside PrestaShop. It ties you to your PrestaShop version, has to be revalidated at every upgrade, and most modules still query the same database as your store.

3. Plug in an external engine

A script tag connects the store to a search engine hosted elsewhere. Nothing depends on your PrestaShop version or theme internals, and the search load leaves your server entirely. This is how Vectail works.

No module to install, no updates to manage. A simple script tag in your PrestaShop theme is all it takes.

1

Create your account and connect your catalog

Sign up at app.vectail.com, connect your Google Merchant Center account. Vectail automatically imports your product catalog.

2

Option A - Via your PrestaShop theme

Add the following tag to the header.tpl file of your theme, before the </head> tag:

header.tpl - your PrestaShop theme
<script
  src="https://cdn.vectail.com/vectail.js"
  data-client-id="YOUR_CLIENT_ID"></script>
3

Google Tag Manager Option B - Via Google Tag Manager (GTM)

If you already use GTM on your store, this is the fastest method - no source code access required. Create a Custom HTML tag, paste the script below, set the trigger to All Pages and publish.

GTM - Custom HTML tag
<script>
  (function() {
    var s = document.createElement('script');
    s.src = 'https://cdn.vectail.com/vectail.js';
    s.setAttribute('data-client-id', 'YOUR_CLIENT_ID');
    document.head.appendChild(s);
  })();
</script>

PrestaShop search, answered

Does Vectail require a PrestaShop module?

No. Vectail is loaded through a script tag, either in your theme's header.tpl or as a Custom HTML tag in Google Tag Manager. There is no module to install, no override to maintain, and nothing to revalidate when you upgrade PrestaShop.

Which PrestaShop versions does it work with?

Any version whose theme can include a script tag, which covers 1.6, 1.7 and the 8.x branch. Nothing in Vectail depends on PrestaShop internals, so a major upgrade of your store does not affect the search.

Do I still need to rebuild the PrestaShop search index?

No. Vectail builds its own index from your Google Merchant Center feed, not from the ps_search_index tables. The native search stays in place untouched, but visitors no longer go through it once the widget is bound to your search bar.

Will it work with my custom theme?

Yes. The widget attaches to the search input already present in your theme through CSS selectors you configure, so the search bar keeps its position and styling. If your theme uses an unusual markup, you set the selector yourself in the dashboard.

What does it cost, and what do I need to get started?

Plans start at €29/month, with a 14-day free trial and no credit card required. The one prerequisite is a Google Merchant Center feed for your catalog, which most PrestaShop stores already maintain for Google Shopping.
