This confirms that MySQL FTS is working as expected. | 1043 | Richard Roe | 0.031008131802082062 |Īs you can see in the above example, All 3 students were returned when we run the query, however, the first record with student name ‘John Roe’ is given more weight because it exactly matched our search terms. | student_id | student_name | Relevance | Output mysql> Select student_id, student_name, match(student_name) AGAINST ('John Roe') as Relevance from students where match(student_name) AGAINST ('John Roe') We have included a new column ‘Relevance’ so that we can be able to see the weight given to each record that matches our search term ‘John Roe’. Mysql>Select student_id, student_name, match(student_name) AGAINST (‘John Roe’) as Relevance from students where match(student_name) AGAINST (‘John Roe’) To test if MySQL FTS is working, we are going to run the command below against our database table:
