Description

This error indicates that a query attempting to perform a full-text search operation (using `MATCH...AGAINST`) is targeting a table or column that lacks a defined `FULLTEXT` index. MariaDB requires a specific `FULLTEXT` index to process these types of advanced searches efficiently.

💬

Error Message

The table does not have FULLTEXT index to support this query

🔍

Known Causes

3 known causes

⚠️

FULLTEXT Index Not Created

The necessary `FULLTEXT` index was never added to the table's columns intended for full-text searching during schema creation or alteration.

⚠️

Index Accidentally Dropped

A previously existing `FULLTEXT` index was inadvertently removed from the table, invalidating subsequent full-text queries.

⚠️

Incorrect Table or Column in Query

The `MATCH...AGAINST` clause in the query is referencing a table or specific column that does not have a `FULLTEXT` index, even if other parts of the database might.

Solutions

3 solutions available

1. Add FULLTEXT Index to Existing Table easy

Temporarily add a FULLTEXT index to resolve the error for immediate use.

1

Identify the table and columns that need to be searched with FULLTEXT. You can usually infer this from the query that triggered the error.

2

Connect to your MariaDB instance.

3

Execute the ALTER TABLE statement to add the FULLTEXT index. Replace `your_table_name` with the actual table name and `column1`, `column2` with the columns you want to include in the index.

ALTER TABLE your_table_name ADD FULLTEXT(column1, column2);

4

Verify that the index has been created by describing the table.

DESCRIBE your_table_name;

2. Create a New Table with FULLTEXT Index medium

Create a new table with the correct FULLTEXT index definition from the start.

1

Determine the schema of your existing table and identify the columns that will be used for FULLTEXT searches.

2

Create a new table with the same schema, but include the FULLTEXT index definition for the relevant columns. Replace `new_table_name`, `your_table_name`, `column1`, `column2`, and other column definitions with your actual schema.

CREATE TABLE new_table_name (
    id INT AUTO_INCREMENT PRIMARY KEY,
    column1 VARCHAR(255),
    column2 TEXT,
    -- other columns...
    FULLTEXT KEY ft_index (column1, column2)
);

3

Copy the data from your old table to the new table.

INSERT INTO new_table_name (column1, column2, -- other columns...)
SELECT column1, column2, -- other columns...
FROM your_table_name;

4

Once data is successfully migrated, you can rename the tables or update your application to use the new table.

3. Modify Table Schema During Creation easy

Define the FULLTEXT index when initially creating the table.

1

When designing or recreating a table that will require FULLTEXT searching, include the `FULLTEXT KEY` definition directly in the `CREATE TABLE` statement. Replace `your_table_name`, `column1`, `column2`, and other column definitions with your actual schema.

CREATE TABLE your_table_name (
    id INT AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(255),
    body TEXT,
    -- other columns...
    FULLTEXT KEY ft_index (title, body)
);

2

Ensure that the columns specified in the `FULLTEXT KEY` are of a suitable type (e.g., `CHAR`, `VARCHAR`, `TEXT`, `MEDIUMTEXT`, `LONGTEXT`).
