Data Bridge Search for keywords not quite working

Data Bridge Search for keywords not quite working

Hi there

I have a field containing post code letters, comma separated. The search consists of lots of tick boxes, one per post code. I'm using the keywords feature and 'contains' and it works fine apart from one, quite serious, issue.

In the UK we have a post code of GL for Gloucester and another of G for Glasgow. If the result contains GL and the search is for G then it's showing the record.

As the data is comma separated I would have thought this would work but after lots of testing I've realised that it's this G being in both G and GL that's causing the problems.

Help needed!

I'm using the latest of every version btw. Latest Data Bridge, latest DW CS6, latest OSX (Mountain Lion).

Many thanks

Jon

any time you are using comma separated lists in your tables, red alarm bels should ring. Comma separated lists are a bad database structure, and will not work properly for what you want to do.

you should be using a linking table to create the many to many relationship of post codes

for example:

maintable:
tableID - Primary Key
etc.....

postcodes:
postcodeID - Primary Key
postcodeValue

itempostcodes:
itempostcodeID - Primary Key
itempostcodeTableID - relates to maintable.tableID
itempostcodePostcodeID - relates to postcodes.postcodeID


this way you store a record to assign each post code to the records in the main table.

you will need to use a join query on the results page and then in the key word, you can use equals instead of includes

Thanks Jason.

I would normally use a many-to-many table but didn't in this instance because of a number of other factors.

Plus, the way WA Search works it was clear that having a comma-separated field would be fine, but it's clearly not working as I expected.

Are you saying I can't do what I need to? Is the only solution to make all the one-character post code areas into two characters (adding a zero for example)?

Thanks for your speedy reply.

"Are you saying I can't do what I need to?"

Yes, using a coma separated list will not work for what you want to accomplish in the way it is set up.

"Is the only solution to make all the one-character post code areas into two characters (adding a zero for example)?"

that could work, sure.

Thanks again Jason. I have now changed all the single-character post codes to two-character and it's working.

All the best
