Hi there. Thank you. But still bit of a confusion left.
Q 1) Its already set as AND logic. See, its like this:
User 1: User bio content: Apple Orange Banana Guava
User 2: User bio content: Apple Banana Guava Orange
So if somebody searches for apple banana, only user 2 should come because apple banana are together in the content (one after the other. Immediate)
If somebody searches for apple orange, User 1 should come up as the entered words are mentioned one after the other.
So is there any way where pair of search keywords are matched the user bio where its one after the other, Continuous.
Q2) I have post tags turned on in ajax search pro autocomplete as you mentioned. Still it does not show up. You mentioned about the fact it may be under different taxonomy. Can you throw little more light on it?
