Install SQL Server Full-Text Search on Linux

  • Artikel

Applies to: SQL Server - Linux

The following steps install Full-Text Search (mssql-server-fts) on Linux. Full-Text Search enables you to run full-text queries against character-based data in SQL Server tables. For known issues for this release, see the Release notes for SQL Server 2022 on Linux.

Note

Before installing SQL Server Full-Text Search, first install SQL Server. This configures the keys and repositories that you use when installing the mssql-server-fts package.

Install SQL Server Full-Text Search for your platform:

Use the following commands to install the mssql-server-fts on Red Hat Enterprise Linux.

sudo yum install -y mssql-server-fts

If you already have mssql-server-fts installed, you can update to the latest version with the following commands:

sudo yum check-update
sudo yum update mssql-server-fts

If you need an offline installation, locate the Full-text Search package download in the Release notes for SQL Server 2022 on Linux. Then use the same offline installation steps described in the article Install SQL Server.

Supported languages

Full-Text Search uses word breakers that determine how to identify individual words based on language. You can get a list of registered word breakers by querying the sys.fulltext_languages catalog view. Word breakers for the following languages are installed with SQL Server:

Filters

Full-Text Search also works with text stored in binary files. But in this case, an installed filter is required to process the file. For more information about filters, see Configure and Manage Filters for Search.

You can see a list of installed filters by calling sp_help_fulltext_system_components 'filter'. For SQL Server, the following filters are installed:

Semantic Search builds on the Full-Text Search feature to extract and index statistically relevant key phrases. This feature enables you to query the meaning within documents in your database. It also helps to identify documents that are similar.

To use Semantic Search, you must first restore the Semantic Language Statistics database to your machine.

  1. Use a tool, such as sqlcmd, to run the following Transact-SQL command on your Linux SQL Server instance. This command restores the Language Statistics database.

    RESTORE DATABASE [semanticsdb]
FROM DISK = N'/opt/mssql/misc/semanticsdb.bak'
WITH FILE = 1,
    MOVE N'semanticsdb' TO N'/var/opt/mssql/data/semanticsDB.mdf',
    MOVE N'semanticsdb_log' TO N'/var/opt/mssql/data/semanticsdb_log.ldf', 
    NOUNLOAD, STATS = 5;
GO

    Note

    If necessary, update the paths in the previous RESTORE command to adjust for your configuration.

  2. Run the following Transact-SQL command to register the semantic language statistics database.

    EXECUTE sp_fulltext_semantic_register_language_statistics_db @dbname = N'semanticsdb';
GO
