MySQL Unique, Index, and Fulltext indexing. All together or one is enough? -


i wanted have 1 specific column unique , optimized searching , sorting. meanwhile same column should have fulltext search capability. should add 3 indexing types (unique, index, , fulltext) on column or not?

please , thanks.

--edit

thanks @fuujin quick comment.

what if have following indexing, no need adding "index" indexing anymore on neither of them, right?

alter table `mytable` add unique (`column_1`, `column_2`);

one column:

unique(x) fulltext(x)

adding index redundant, since unique is index.

two columns:

unique(x,y)  -- order depend on queries (see below) fulltext(x,y) fulltext(x), fulltext(y) -- may need these (see below)

where x > 5 , y = 2 needs (y,x) order

if search 1 of 2 columns, such match(x) against(...), innodb, not myisam, needs fulltext indexes.
