 table.create_fts_index("text", use_tantivy=False, with_position=True)
 ```
 This will allow you to search for phrases, but it will also significantly increase the index size and indexing time.

+## Incremental indexing
+
+LanceDB supports incremental indexing, which means you can add new records to the table without reindexing the entire table.
+
+This can make the query more efficient, especially when the table is large and the new records are relatively small.
