 Table views that support full-text search can be queried using the ``?_search=TERMS`` query string parameter. This will run the search against content from all of the columns that have been included in the index.

 You can include full-text search results in custom SQL queries. The general pattern with SQLite search is to run the search as a sub-select that returns rowid values, then include those rowids in another part of the query.
