Question

How to make a search mechanism like that:

when user type: "sól"
two words are searched: "sol" & "sól"

and there are search results for both words

Answer 1

You can use a mySQL collation that is “Umlaut insensitive”, for example utf8_general_ci.

Either

• Create a specialized search column that is utf8_general_ci

• Or define the collation while searching, which is easier but less good for performance.
  This should work:

  select * from column where name='sól' COLLATE utf8_general_ci;
  

  However, doing this may degrade performance in some situations, because I’m quite sure the fulltext index can’t be used when specifying the collation like this.
