Hi,

I have table like this:

Expand|Select|Wrap|Line Numbers
  1.  
  2. select * from sampletest;
  3.  
  4. | title                                                                                                                                                                                                                               | description                                                                                                                                                                                                                                                                                                                    |

  9. 2 rows in set (0.00 sec)
  10.  
I have query terms submitted by user like this:

query1= regular AND expressions

query2=regular AND (expressions OR AWK)

I want to match ( title and description both) with these query terms and retrieve the matched title and descriptions.

I have created fulltext on title and description.

I am not getting how to form a select query which satisfies the above criteria!!!

Output should be like this:

Expand|Select|Wrap|Line Numbers
  1.  
  2. AWK was probably second after Snobol a string processing language that extensively use regular expressions [ in title]
  3.  
  4. In 1985, just before Perl, a new version made the programming language more powerful, introducing user-defined functions, multiple input streams, and computed regular expressions. The version in System V Release 4 added some new features and also cleaned up the behavior in some of the ``dark corners' of the language [in description]
  5.  
  6.  
Basically i want to retrieve the matched contents with the given queryterms.

I tried like this for title only but i don't know how to combine both title and description.

Expand|Select|Wrap|Line Numbers
  1.  
  2. select title from sampletest where title RLIKE '[[:<:]]regular[[:>:]]' and title RLIKE '[[:<:]]expression[[:>:]]' :]]';
  3.  
  4. +-------------------------------------------------------------------------------------------------------------+
  5. | title                                                                                                       |
  6. +-------------------------------------------------------------------------------------------------------------+
  7. | AWK was probably second after Snobol a string processing language that extensively use regular expressions. | 
  8. +-------------------------------------------------------------------------------------------------------------+
  9. 1 row in set (0.01 sec)
  10.

To match for both title and description you just use AND on the where clause.
To combine returned results you just add them together using CONCAT.

Is that what you want?

Hi,

Ya in a way like that!!!

Can u tell me the query???

can u explain more !!!

I just want to retrieve title and description of the matched query (query1= regular AND expressions query2=regular AND (expressions OR AWK))

I should check either title or description that has these queryterms.

It can be in one or it can be in both also!!!

How to do that???

If this is your condition then you simply check in title or description, no need to check in both.
Expand|Select|Wrap|Line Numbers
  1. where (title LIKE someCrypticStuffHere OR description like evenMoreCrypticStuff)
  2. OR (title like 'AWK%'   OR description like 'AWK%'

Hi,

But the order is changed.

I have AND operator in between the queryterms how can i handle that??

I have another example query3=regular AND perl AND (expressions OR AWK))

In such case the order becomes very important.

I want to retrieve title OR description (both) that has all terms i.e regular, perl expressions OR awk!!

How can i do that?
