The LogReduce® algorithm uses fuzzy logic to cluster messages together based on string and pattern similarity. Use the LogReduce button and operator to quickly assess activity patterns for things like a range of devices or traffic on a website.

:::important
The `summarize` operator has been renamed to `logreduce` to match the **LogReduce** button on the **Messages** tab. Both operators will continue to work in search queries as synonyms for a limited time. We recommend that you rewrite saved queries replacing summarize with LogReduce.
