Re: Highlighting

[Scott Derrick]

I was pretty sure I tried that, though I thought if you don't specify it 
just uses the search terms?

If I just search for "calvin" and don't specify a field, what do I 
assign hl.fl?

Scott - doesn’t look you’ve specified hl.fl specifying which field(s) to 
highlight.

p.s. Erick Erickson surely likes your e-mail domain :)

I guess I really don't get Highlighting in Solr.

We are transitioning from Google Custom Search which generally sucks, but does 
return nicely formatted highlighted fragment.

I turn highlighting on hl=true in the query and I get a highlighting section 
returned at the bottom of the page, each identified by the document file name 
with a empty {} .  It doesn't matter what I search for, plain text, a field, I 
get a list of documents followed by an empty brace?

I haven't made any changes to the default settings
