Increasing the highlight snippet size
Hi, I have been trying to increase the size of the highlight snippets using "hl.fragSize" parameter, without much success. It seems that hl.fragSize is not making any difference at all in terms of snippet size. For example, compare the following two set of query/results: http://10.1.1.51:8983/solr/select?q=%28bookCode%3abarglewargle+AND+content%3awriting+AND+id:6970%29&rows=1&sort=id+asc&fl=id%2cbookCode%2cnavPointId%2csectionTitle&hl=true&hl.fl=content&hl.snippets=100&hl.fragSize=10&hl.maxAnalyzedChars=-1&version=2.2 to write a http://10.1.1.51:8983/solr/select?q=%28bookCode%3abarglewargle+AND+content%3awriting+AND+id:6970%29&rows=1&sort=id+asc&fl=id%2cbookCode%2cnavPointId%2csectionTitle&hl=true&hl.fl=content&hl.snippets=100&hl.fragSize=1000&hl.maxAnalyzedChars=-1&version=2.2 to write a Because of our particular needs, the content has been "spanified", each word with its own span id. I do apply HTMLStrip during the index time. What I would like to do is to increase the size of snippet so that the highlighted snippets contain more surrounding words. Although hl.fragSize went from 10 to 1000, the result is the same. This leads me to believe that hl.fragSize might not be the correct parameter to achieve the effect i am looking for. If so, what parameter should I use? Thanks!
Re: Increasing the highlight snippet size
I was just trying to set it a ridiculously large number to make it work. What I am seeing is that hl.fragsize doesn't seem to make any difference in term of highlight snippet size... I just tried the query with hl.fragsize set to 1000. Same result as 10.

Re: Increasing the highlight snippet size
Well, only after I posted this question in a public forum, I found the cause of my problem. I was using "hl.fragSize", instead of "hl.fragsize". After correcting the case, it worked as expected. Thanks.
