Hi Ian, Thanks for the reply. I am not sure if the bq solution will b able to solve the problem. Let me explain with an example -
document 1 - (some text) IBM - 0.6 Google - 0.1 Apple - 0.4 Now suppose I index the document based on the "company name" and "confidence scores" separately and search using the bq where the Numeric Field search is based on "anything below 0.5" and text = "IBM". Here, by mistake the document 1 will be chosen (as it has been stored with 0.6, 0.1 and 0.4). But actually it should not be - as the "IBM" score is 0.6. So in gist - this problem needs some sort of linking between the company name and the scores. --d On Wed, Mar 21, 2012 at 10:41 AM, Ian Lea <ian....@gmail.com> wrote: > Why do you want to link name and confidence in one field?
