Hi!
Just wanted to close the loop here.
I'm pretty sure this has something to do with the default _text_ "catchall"
field being a slightly differently type ('text_general') from all my
textual fields ('text_en'). A few things I tried support that hypothesis:
- Specifying fields for terms correctly yields highlights consistently
(e.g. "hello" doesn't work but "subject:hello" always does).
- Creating a different catchall field with same type as all my textual
fields ('text_en') and making that the default field yields highlighting
results that work properly and consistently.
- Finally -- I need to use a friendlier parser anyway. Using edismax for
all my queries -- and eliminating my catchall field -- yields highlighting
results properly and consistently.
I've got this working, but I'm curious to know if this is what's happening
more around precisely why. If anyone more knowledgable has thoughts or
pointers to writing on how highlighting works internally, I'd really
appreciate it!
Cheers,
Vikram
