# Output compression When a large number of results are produced, along with many filter options, the amount of data returned by FactFinder rises quickly. This can cause the network data transmission time to form a significant component of the overall search response time. If supported by the web server, the server response can be sent after having been compressed using the GZIP algorithm, to heavily reduce the data volume. Depending on the programming language used, however, it may be necessary to use client-side code to support this compression method as well. The client must explicitly request compressed output using the value “gzip” in the request header “Accept-Encoding”. --- # 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://docs.fact-finder.com/integration/factfinder-search-integration/output-compression.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.
