I have drupal 6 installed on linux with mysql 5.6 and php 5.4. All working.
But search give error:
You must include at least one positive keyword with at least 3 characters. . I enter word with 5-6 characters.
I try see logs of server and php, errors: 0. In admin panel: admin/settings/search all indexed on 100%. What this can be? I think, that drupal incorrectly checks for counting characters in search. May be need a module php? But I have installed all modules..
In database I have all tables on InnoDB.
