Search for special chars in mysql full text search

Question

I am doing a search function in php , and I am allowing BOOLEAN search, but when I enter text containing chars like @ , the query fails.

For example, when I search for @everyone , it throws an error. I tried to solve this by adding doublequotes, but it doesn't work as expected, since for the search @everyone , it works but returns rows containing everyone and @everone .

I would like to know how we can search for words containing special chars in mysql full text search

Here's my query (simplified) :

SELECT * FROM messages WHERE MATCH(body) AGAINST ('@everyone' IN BOOLEAN MODE)

Answer 1

By default, MySQL does not treat '@' as a valid character for a word. If you want to treat '@' it, then review the documentation on the subject.

After you have made the changes, then you will need to re-build your index.
