Perform a semantic search in a script

If a table has been vectorization enabled, you can query it using semantic similarity directly in a script.

Prerequisites

You have created a script or have an existing one open in edit mode.
The target table has vectorization enabled. See Enable vectorization for a table definition.
You have added the table to the script.

Procedure

Use the findSimilar method on the table entity, providing a natural-language search string and any standard TypeORM query options:

const data = await entities.testtable.findSimilar({
    search: "My query",
    select: ["id"], // select any fields you need
    where: { id: Not("test") }, // standard TypeORM where clause
    // additional TypeORM arguments
});

Result

The method returns the rows whose vector representation is most similar to the search string, ranked by semantic similarity.
