Here is my index structure.
for each document:
Field articleTitle (only one value)
Field majorHeading (multiple values)
Field minorHeading (multiple values)
I use heading (can be both majorHeadings or minorHeadings) to search. What
I want is that majorHeading is more important than minorHeading. I can
boost the majorHeading during index in two ways
method 1: for every major field of the same document,
field.setBoost(2f)
method 2: only the first major field of the same document,
field.setBoost(2f)
Looks like both ways give me the correct result.
Questions 1 : What is the difference between boosting only the first field
or boosting all fields for a multivalued field?
In addition, I can also boost the majorHeading during searching if I choose
not to boost in index time
Question 2 What is the trade-off between index boost and search boost?
I will appreciate your help a lot.
Best regards,
Qi Li
