                 To enable full-text search for a table called  items  that works against the  name  and  description  columns, you would run this SQL to create a new  items_fts  FTS virtual table: 
                 CREATE VIRTUAL TABLE ""items_fts"" USING FTS4 (
    name,
    description,
    content=""items""
); 
                 This creates a set of tables to power full-text search against  items . The new  items_fts  table will be detected by Datasette as the  fts_table  for the  items  table. 
                 Creating the table is not enough: you also need to populate it with a copy of the data that you wish to make searchable. You can do that using the following SQL: 
                 INSERT INTO ""items_fts"" (rowid, name, description)
    SELECT rowid, name, description FROM items; 
                 If your table has columns that are foreign key references to other tables you can include that data in your full-text search index using a join. Imagine the  items  table has a foreign key column called  category_id  which refers to a  categories  table - you could create a full-text search table like this: 
                 CREATE VIRTUAL TABLE ""items_fts"" USING FTS4 (
    name,
    description,
    category_name,
    content=""items""
); 
                 And then populate it like this: 
                 INSERT INTO ""items_fts"" (rowid, name, description, category_name)
    SELECT items.rowid,
    items.name,
    items.description,
    categories.name
    FROM items JOIN categories ON items.category_id=categories.id; 
                 You can use this technique to populate the full-text search index from any combination of tables and joins that makes sense for your project.","[""Full-text search"", ""Enabling full-text search for a SQLite table""]","[{""href"": ""https://sqlite-utils.datasette.io/"", ""label"": ""sqlite-utils""}]"
