Question

I need to search some data in my database. But main problem is that i search with match against:

...MATCH(description) AGAINST ("*52*" in boolean mode)

But on one iteration (or more, but with one query) i must search not only for 52, but for 50,51,52,...,59 as before…
But is it real to do?
Also i do it with RoR:

 @accums = Accumulator.find(:all, :conditions => ["MATCH(description) AGAINST (? in boolean mode)", size])

Or i will need to do iterator on rails, and search for all of them iteration by iteration?

Answer 1

If you say:

 MATCH(description) AGAINST ("*52*" in boolean mode)

Against a row where ‘description’ is:

34,520,1000,9000

or

34,452,1000,9000

or

34,4525,1000,9000

You will get a match. Is that your desired result?

I am guessing not.

I think what you want is:

MATCH(description) AGAINST ("52" in boolean mode)

And to handle multiple matches you would want:

MATCH(description) AGAINST ("51 52 53" in boolean mode)

Examples:

34,520,1000,9000
// no match

34,452,1000,9000
// no match

34,52,1000,9000
// match

34,53,1000,9000
// match

34,52,53,9000
// match
