Sqlite - how to search a table with a list of terms from another table

Here is a little example of how brilliant Sqlite is :

sqlite> .schema  country
CREATE TABLE country(id integer primary key autoincrement, name text);
sqlite> .schema search
CREATE TABLE search(term text);
sqlite> select * from country ;
id|name
1|France
2|Czech Republic
3|Italy
4|Great Britain
5|Ireland
6|Slovakia
7|Senegal
sqlite> select * from search ;
term
%fr%
%cz%
%ir%
ai
sqlite> select a.name from country a join search b on a.name like "%"||b.term||"%" ;
name
France
Czech Republic
Great Britain
Ireland

NB : the || is used for Sqlite for concatenation
