Hey Matt:
I have been facing the same issue. I have a text field that I
highlight along with other fields (may be 10 others fields). But If I enable
highlighting on this text field that contains large number of
characters/words ( > 100 000 characters) , highlighting suffers performance.
Queries return in about 15/20 seconds with this field enabled in highlights
as compared to less than a second WITHOUT this enabled in highlight.
I did try termvector=true , but I did not see any performance
gain either.
Just wondering if you were able to solve your issue OR tweak the performance
in any other way.
BTW , I use solr 1.3.
