Highlight question
I just started working with the highlighting. I am using the default
configurations. I have a field that I can get a single highlight to occur
marking the data.
What I would like to do is this,
Given a word say 'tumor', and the sentence
the lower tumor grew 1.5 cm. blah blah blah we need to remove the tumor in
the next surgery
I would like to get em the lower tumor grew 1.5 cm /em. blah blah
blah we need to ...em remove the tumor in the next /em. surgery
Thus finding multiple references to the work and only grabbing a few words
around it.
In the solrconfig.xml I have been able to change the hl.simple.pre/post
variable, but when I try to change the hl,regex pattern or the hl.snippets they
don't have any effect. I thought the hl.snippets would alow me to find more
than one and highlight it, and well I tried a bunch of regex patterns but they
didn't do anything.
here is a snippet of the config file.
Any help is appreciated.

I thought the hl.snippets would alow me to find more than one and highlight it, and well I tried a bunch of regex patterns but they didn't do anything. int name=hl.snippets4/int param should go to under default section of your default SearchHandler. requestHandler name=standard class=solr.SearchHandler default=true lst name=defaults str name=echoParamsall/str int name=hl.snippets4/int /lst /requestHandler Also hl.formatter=regex paremter is required to activate regular expression based fragmenter.
