+=== Vector Search Queries
+
+Projections are the foundation for querying data returned in a different form than the entity.
+While Cassandra's primary use-case follows a key-value model – storing what you retrieve – Vector search is different.
+Running Vector search queries typically results in an aggregation or report-like result set.
+A typical query would return some form of content (such as a `text` column) along with its score (or distance) to the actual vector.
+
+Consider the following domain model:
+
+.Vector Search model
+====
+[source,java]
+----
+include::example$VectorSearchExample.java[tags=class]
+----
+====
+
+`Comments` is the domain type defining a vector column and the `comment` column.
+
+Running a Vector Search requires usage of `ANN` sorting and would typically define a similarity function to determine its distance from the given vector.

+Make sure to declare an alias to map the result onto `CommentSearch.similarity` as result mapping uses column names.
+<3> Use the `VectorSort.ann(…)` to define the sort order in comparison to the given vector.
