I had a hard time to log onto U.T
because an error has occurred to the internet service provider of mine.
It's too late but I wanna ask you some more questions if you don't mind.
If I understand you correctly,
Do you mean that a record in a target table can have more than one
corresponding record in the child table which contains Keywords?
For instance,
If the kewords of the current record is "black","color","paint","red"
Should I make three corresponding records in child keyword table
each contains one of the keywords and target Id?
If it's true, is there any possiblity that the child table's gonna have too many records?
Is it still fast enough when the number of records gets over 100,000?
