# Advanced filtering "And/Or"

Advanced filtering lets you narrow the dataset using **AND** and **OR** logic, so you can build precise filtering.

#### How filtering logic works

Tembi uses two levels of logic:

**1) Filters within a group use AND**\
If you add multiple filters inside the same group, a webshop must match **all** of them to be included.

Example (one group):

* Webshop platform = Shopify, WooCommerce
* Growth prediction = high, very high
* Municipality = Stockholm, Göteborg

Result: webshops that match all three.

**2) Multiple filter groups use OR**\
If you create an additional filter group, the results will include webshops that match **either** group.

Example (two groups):

* **Group 1**: Platform + growth + municipality\
  **OR**
* **Group 2**: Municipality + delivery method (for example excluding a method)

Result: webshops that match group 1 **or** group 2.

#### Build a filter group (AND)

1. Open **Filters**.
2. Click **Add another filter** to add criteria within the same group.
3. Keep adding filters until the group represents one clear segment.

Tip: use the search field in the filter list (for example, type “delivery”) to find relevant filters faster.

#### Add a second filter group (OR)

Use a second group when you have two valid routes into the same shortlist.

1. Click **Add new filter group**.
2. Add the filters for the second segment.
3. The dataset will now include webshops that match **group 1 or group 2**.

This is useful when your ICP has more than one pattern (for example, “fast-growing Shopify stores in big cities” **or** “any store in those cities using a specific delivery setup”).

#### Save filters as favourites

When you’ve built a useful setup, save it so you can reuse it.

* Open **Saved filters**
* Save the current filter setup with a clear name (for example “Nordics - high growth Shopify”)
* Reopen it any time to return to the same scope without rebuilding it

Good practice: create separate saved filters for **prospecting**, **key accounts**, and **market views** to avoid constant edits.

#### Practical guidance

* Use **AND** to define one precise segment.
* Use **OR** when you want multiple segments in one view.
* If results get noisy, split into separate saved filters rather than adding more OR groups.
* If results get too small, remove one filter at a time (often geography or technology are the biggest limiters).
