+Configuring FTS using sqlite-utils
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`sqlite-utils <https://sqlite-utils.readthedocs.io/>`__ is a CLI utility and Python library for manipulating SQLite databases. You can use `it from Python code <https://sqlite-utils.readthedocs.io/en/latest/python-api.html#enabling-full-text-search>`__ to configure FTS search, or you can achieve the same goal `using the accompanying command-line tool <https://sqlite-utils.readthedocs.io/en/latest/cli.html#configuring-full-text-search>`__.

+Configuring FTS using csvs-to-sqlite
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If your data starts out in CSV files, you can use Datasette's companion tool `csvs-to-sqlite <https://github.com/simonw/csvs-to-sqlite>`__ to convert that file into a SQLite database and enable full-text search on specific columns. For a file called ``items.csv`` where you want full-text search to operate against the ``name`` and ``description`` columns you would run the following::

+    $ csvs-to-sqlite items.csv items.db -f name -f description
