Best way to get most relevant data from table MYSQL

I have an entry table with the columns as shown below:

id | ans_1 | ans_2 | ans_3   | ans_4    | ans_5   | date

Some sample data in the table as shown below:

1  | foo   | bar   | foobar  | bar foo  | foofoo  | 2011/9/15**
2  | foo2  | bar2  | foobar2 | bar2 foo | foofoo2 | 2011/9/17**
3  | foo3  | bar3  | foobar3 | bar foo3 | foo3foo | 2011/9/20**

I would like to search for the most relevant data from the entry table above provided by 5 answer sets.

My solution #1:

SELECT * FROM entry 
WHERE ans_1 LIKE '%$answer_set_1_en%' 
AND ans_2 LIKE '%answer_set_2_en%' 
AND ans_3 LIKE'%answer_set_3_en%' 
AND ans_4 LIKE '%answer_set_4_en%' 
AND ans_5 LIKE '%answer_set_5_en%';

However, I have 2 sets of answers (diff language sets) to compare now, here comes my solution for #2:

SELECT * FROM entry 
WHERE (ans_1 LIKE '%$answer_set_1_en%' 
AND ans_2 LIKE '%answer_set_2_en%' 
AND ans_3 LIKE '%answer_set_3_en%' 
AND ans_4 LIKE '%answer_set_4_en%' 
AND ans_5 LIKE '%answer_set_5_en%')
OR
(ans_1 LIKE '%$answer_set_1_jp%' 
AND ans_2 LIKE '%answer_set_2_jp%' 
AND ans_3 LIKE '%answer_set_3_jp%' 
AND ans_4 LIKE '%answer_set_4_jp%' 
AND ans_5 LIKE '%answer_set_5_jp%');

But, entry may mix with two languages, so my third attempts:

SELECT * FROM entry 
WHERE (
(ans_1 LIKE '%$answer_set_1_en%' OR ans_1 LIKE '%$answer_set_1_jp%') 
AND (ans_2 LIKE '%answer_set_2_en%' OR ans_2 LIKE '%$answer_set_2_jp%')
AND (ans_3 LIKE '%answer_set_3_en%' OR ans_3 LIKE '%$answer_set_3_jp%')
AND (ans_4 LIKE '%answer_set_4_en%' OR ans_4 LIKE '%$answer_set_4_jp%')
AND (ans_5 LIKE '%answer_set_5_en%' OR ans_5 LIKE '%$answer_set_开发者_StackOverflow中文版5_jp%'));    

Is the third query optimized/efficient enough already? May I know any other alternative ways of querying the most relevant columns?

If you want to allow for a mix of english and japanes answeres then this looks like the way to go. Note that if you get a lot of entries this aproach will kill you, doing that many LIKE compares is going to be really slow.

Could you give examples on a valid answer_set?

Another approach is to do this same compare at the time of saving the entry (application side or with a trigger) that besides storing the actual answers also stores how many of them are correct. Then a simple

select * from entry where correct_answers = 5

is going to give you the wanted rows really quick.
