Effects of setting termOffsets to false

[Zheng Lin Edwin Yeo <ed...@gmail.com>]

Hi,

I would like to find out, is there any implication of using termVectors,
but setting the term offsets to false?

This is what I am setting for my
<field name="tag" type="string" indexed="true" stored="true"
multiValued="true" required="false" termVectors="true" termPositions="true"
termOffsets="false"/>

I'm currently setting the termOffsets to false, because when I set it to
true, I'm getting this error during highlighting if I have 3 or more values
in my tag field.
