5. Search & Filtering
Quick Text Search
Type in the search field to instantly filter products. The search checks across:
- Product name
- Reference (SKU)
- EAN-13
- MPN, UPC, ISBN
- Combination reference, EAN, MPN, UPC, ISBN
- Manufacturer name
- Supplier name
The search is accent-insensitive - typing "cerveny" will match "červený".
Client-side mode (<3,000 rows): Filtering is instant - no server requests. Server-side mode (3,000+ rows): The search is debounced (300 ms delay after you stop typing) to minimize server requests.

Category Tree Filter
Click the category dropdown to open a hierarchical category tree. Select one or more categories to filter products. Selecting a parent category automatically includes all child categories.
Your selection is saved in the browser - it will be restored when you return to the page.

Predefined Filter Pills
Three quick-filter buttons appear above the grid (if enabled in configuration):
| Filter | What it shows |
|---|---|
| New | Products added within the last X days (configured in PrestaShop's "Number of days for which the product is considered new"). |
| Best sellers | Products with at least one recorded sale. |
| On sale | Products with an active specific price or the "on sale" flag enabled. |
Click a pill to activate it (it highlights). Click again to deactivate. Multiple pills can be active simultaneously. If a filter would return zero results, its pill is hidden.
Click the X button to clear all active filters at once.

Column Filters
Click the filter icon in a column header (for numeric columns like Stock, Price) to open the column filter. Supported operators:
- Equals
- Not equal
- Less than
- Greater than
- In range (between two values)
