# Selecting products When a feed of products has been defined the Products panel will show all products of your feed. Something similar to: ![](/files/An2pOgEYje1m1dXV4HTK) By default, all products will be used in your pickzen. If you only want to use a reduced set of products, you can select them one by one, or define a rule to select them automatically. ### Selecting products one by one In order to select your products one by one, simply mark those you want to be used in your pickzen: ![](/files/uy1p5A9NiBKTTDt2bwSC) In this example, only 4 products were selected and will be used for recommendation. ### Selecting products by rules If the feed contains hundreds or thousands of products, selecting them one by one can be a heavy task. In these cases, selecting products by rules can be of help. Click on the *by rules* link: ![](/files/JhBSHA1zHqm0FmtxxjFf) The products panel will change to a rules panel: ![](/files/WsCjTt2J2uhIT7ghxJ12) Clicking on Siple Rule we can define de rule to select the products. For example, all products with tag *flat:* ![](/files/M0nGEhMdBtLu7wlZGHLS) In our Plus and Pro plans, more complex rules can be defined, combining AND / OR expressions. For example, all shoes with tags *heel* and *fashion*: ![](/files/VijElrtnkiH2WR95G2PL) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
