# Dynamic filters INTELIE Live supports that the Pipes filters react to dynamic parameters of a query. This is useful to support interfaces that allow the user to change the filters without the need of changing the query expression. The dynamic values are passed in the `lookupValues` argument of the Query object. This argument is a `map>`, where the key is the name of a Lookup Table and the value is a list of the desired keys in that Lookup Table. INTELIE Live will apply to the query the values corresponding to each of those keys. ### Lookup Tables Lookup Tables are structures that associate multiple values with keys. They can be created programmatically through the API or through the web interface. A Lookup Table created programmatically will not be editable through the web interface. ![Web interface to manage lookup tables](https://3214244039-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lov7jZs3pzHFyAcuuli%2F-Lp3WebmWrIzuJ3zH-C2%2F-Lp3_XDjPTTyyPXAjapO%2Fimage.png?alt=media\&token=b567757a-01d0-41d9-9a24-454d646d76e3) ### The @@lookup macros The `@@lookup` macro allows the lookup values to be used on the query. For every Lookup Table created, a `@@lookup.name_of_the_table` macro will be available. ![Example of the @@lookup macros](https://3214244039-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lov7jZs3pzHFyAcuuli%2F-Lp3WebmWrIzuJ3zH-C2%2F-Lp3b8qJiWxaDK6zs4IN%2Fimage.png?alt=media\&token=0906cf7e-e1dc-4783-9f81-d23c28e763bb) When this macro is used on a query, it will be dynamically replaced by the values corresponding to the Lookup Table keys in the `lookupValues` query argument. ### The lookup functions Some functions are also created to facilitate the use of the Lookup Tables keys and values on any Pipes query. ![Example of auxiliar Pipes functions](https://3214244039-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lov7jZs3pzHFyAcuuli%2F-Lp3WebmWrIzuJ3zH-C2%2F-Lp3bGLlRMhDNWWzETSP%2Fimage.png?alt=media\&token=512b3134-662c-4033-a236-b1e136fa1fbb) --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://platform.intelie.com/pipes-queries/dynamic-filters.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
