Abnormal WSS Site Search

After a WSS site was created on the virtual machine today, it was found that no documents could be searched during the search. I searched the internet and found that the full-text search was not opened. After the full-text search service is started, run sp_fulltext_database "enable" in the query analyzer, open SQL Enterprise Manager, and open <Site_name>_ Full-text directory in site, select IX _ <Site_name>_ Site right-click and select "recreate directory. After running, you can search for the result in WSS.

What I don't understand here is what sp_fulltext_database "enable" means, and you don't need to set Scheduling. If you need to set it reasonably, please give me some advice.
