MySQL Full Text Search - So many Indexes

[Natasha na]

1) I am using XAMPP. MySQL Server version: 10.1.9-MariaDB

Table corp_news has around 10,000 rows.

I am using below query to create Index using PHPMyADmin.

ALTER TABLE corp_news ADD FULLTEXT INDEX `corp_nz` (`content` ASC, `subject` ASC);

After running this query, On left hand side menu, when i click the "index" from the tree i see many indexes named like

content2
content3
content4
.
.
.
.
content37
subject2
subject3
subject4
.
.
.
.
subject36
subject37

I thought it would create only one Index table named "corp_nz". what the heck so many index tables about? Is this normal?



2) If this is the case, how can i even drop the full text index on "corp_news" table?
