It can occur in these cases:
- The default sorting of the Search Results Widget differs from Relevance. You can check out that in the Searchanise control panel > Search results widget section > Content tab > Default sorting option.
- You’ve set up merchandising rules, so the promoted products are displayed at first. You can check out that in the Searchanise control panel > Merchandising section > Products or Categories tabs.
- Products that match the search query are out-of-stock, and you’ve hidden such products from search in the Magento settings (Magento admin panel > Stores > Configuration > Catalog > Inventory > Stock options > Display Out of Stock Products option), or you’ve adjusted to show them at the end (the Searchanise control panel > Preferences section > Products tab > option).
- Some of the product fields are disabled and the app doesn’t search through them. You can check out that in the Searchanise control panel > Preferences section > Products Fields tab.
