As translated, Mroonga is a storage engine for MySQL. It provides a fast full-text search function for all MySQL users.
Here is a direct demonstration of how to enable the mroonga storage engine on MariaDB
1) load the mroonga plug-in
MariaDB [(none)] > INSTALL SONAME 'ha_mroonga'
MariaDB [(none)] > CREATE FUNCTION last_insert_grn_id RETURNS INTEGER SONAME 'ha_mroonga.so'
2) build a table and test it.
MariaDB [(none)] > create database jerry
MariaDB [(none)] > use jerry
MariaDB [jerry] > create table T1 (id int not null,name varchar (100) not null,notes text,fulltext index (notes)) engine=mroonga
3) insert some data randomly
MariaDB [jerry] > insert into T1 values ("wipe", "I won't tell you")
Query OK, 1 row affected (0.00 sec)
MariaDB [jerry] > insert into T1 values (2'la','I won't tell you')
Query OK, 1 row affected (0.01sec)
MariaDB [jerry] > insert into T1 values.
Query OK, 1 row affected (0.00 sec)
MariaDB [jerry] > insert into T1 values (4Dasoma Investment Co., Ltd.)
Query OK, 1 row affected (0.00 sec)
MariaDB [jerry] > insert into T1 values (5 miner kukumimiluluju 'Sema cross-border e-commerce co., Ltd')
Query OK, 1 row affected (0.00 sec)
MariaDB [jerry] > insert into T1 values (6) 'Wang Sicong', 'Wang Dad United Da Senma Cross-Border E-commerce Co., Ltd')
Query OK, 1 row affected (0.00 sec)
4) query with the following command
MariaDB [jerry] > select * from T1 where match (notes) against ('Big Senma' in BOOLEAN MODE)
+-+
| | id | name | notes | |
+-+
| | 4 | victor | Da Senma Investment Co., Ltd. |
| | 6 | Wang Sicong | Father Wang United Da Senma Cross-border E-commerce Co., Ltd. |
+-+
2 rows in set (0.00 sec)
5) through the execution plan, we can see that the full-text index notes has been used, and only one row needs to be scanned
MariaDB [jerry] > explain select * from T1 where match (notes) against ('Big Senma' in BOOLEAN MODE)
+-+
| | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+-+
| | 1 | SIMPLE | T1 | fulltext | notes | notes | 0 | | 1 | Using where with pushed condition |
+-+
1 row in set (0.00 sec)
