First, set the format of the SELECT statement's output so it is easily readable. Set the width of the text column to 40 characters:
COLUMN text FORMAT a40;
Now query the table with the SELECT statement with CONTAINS. This retrieves the document IDs that satisfy the query. The following query looks for all documents that contain the word France:
SELECT SCORE(1), id, text FROM docs WHERE CONTAINS(text, 'France', 1) > 0;
SCORE(1) ID TEXT
