To create a segment go to the Segments tab and click on the floating icon on the bottom right.
Then,
1. Give the segment any name that you want. (ex: Batman).
2. You can select a specific website or All Websites to get data from all the available websites.
3. Keywords are optional but very useful, for example, if you want any LEGO set that includes Batman no matter if it’s in the DC theme, or Technic theme, or any other theme, you can achieve that by simply using the word batman in the keywords field.
4. You can choose a specific theme or leave it empty.
5. You can choose a specific availability like In Stock only or show everything excluding the retired LEGO Sets.
6. You can put a min price and max price if you have a specific budget or simply want to see LEGO sets within a specific range of price.
7. You can choose to see all LEGO sets or on sale only LEGO sets.
As explained above, the possibilites are limitless and you can get very specific and highly advanced results very quickly.
