+      # resultset which is already filtered by other conditions (< 10_000 records).
+      #
+      # ==== Parameters
+      # * +search+ - [String] the user provided search string
+      # * +rules+ - [{ column: COLUMN, multiplier: 1 }, { column: COLUMN_2, multiplier: 0.5 }] rules for the scoring.
+      #   * +column+ - Arel column expression, example: Project.arel_table["name"]
+      #   * +multiplier+ - Integer or Float to increase or decrease the score (optional, defaults to 1)
+      #
+      # ==== Use case
+      #
+      # We'd like to search for projects by path, name and description. We want to rank higher the path and name matches, since
+      # it's more likely that the user was remembering the path or the name of the project.
+      #
+      # Rules:
+      #   [
+      #     { column: Project.arel_table['path'], multiplier: 1 },
+      #     { column: Project.arel_table['name'], multiplier: 1 },
+      #     { column: Project.arel_table['description'], multiplier: 0.5 }
+      #   ]
+      #
+      # ==== Examples
+      #
+      #  Similarity calculation based on one column:
+      #
+      #  Gitlab::Database::SimilarityScore.build_expession(search: 'my input', rules: [{ column: Project.arel_table['name'] }])

+      #  Similarity calculation based on two column, where the second column has lower priority:
+      #
+      #  Gitlab::Database::SimilarityScore.build_expession(search: 'my input', rules: [
+      #    { column: Project.arel_table['name'], multiplier: 1 },
+      #    { column: Project.arel_table['description'], multiplier: 0.5 }
+      #  ])
