Erik,
What is generally the reason for indexing both individual fields, and the
general-purpose "content" field ?
Also, if we search in the general-purpose "content" field, wouldnt this
problem occurs. Let say we have 2 fields and the following values:
name : John Smith
food : subway sandwich
Very good advice!
With the previous code you gave me, I was able to get everything for 2.0!
good call!

No, that article has not been updated for the 2.

You are not kidding. I keep finding this tougher and tougher. Originally
my method worked for most simple queries, but not all. I improved it to
cover some more ground, allowing some modestly complex queries, but now
even that improvement seems woefully inadequate for solving the general
case.
