+Options to create an `FTS` index

+## Properties
+
+### withPosition?
+
+> `optional` **withPosition**: `boolean`
+
+Whether to store the positions of the term in the document.
+
+If this is true then the index will store the positions of the term in the document.
+This allows phrase queries to be run. But it also increases the size of the index,
+and the time to build the index.
+
+The default value is true.
