thank you for your response,
I think that I wasn't enough clear in my last post, (I have already read
http://wiki.apache.org/solr/HighlightingParameters before asking my question
last time)this is what I want to do:
now solr give in response one fragment and I know
hl.fragsize=<size> to set the desired fragment size, and
hl.snippets=<number> to set the number of returned snippets/fragments. but
hl.snippets is useful if we deal with multi-valuated field (for instance
the feature field in the solr schema example) but in my case I have a single
field myText which type is text in each document so here
hl.snippets=<number> has no sense, either used or not the highlighted
result is the same.
here is what I want to do.
lucene provide overloaded methodes getBestFragment(....) to return
fragments :
I think that solr classes use this methode
highlighter.getBestFragment(tokenStream, text)
which return one fragment containing the first occurence of the searched
wordhighlighted , but I dont want only the first occurrence but the N(2th or
3th.....) th one's
and I want to replace the previous methode by
String result =
highlighter.getBestFragments(tokenStream, text, 5, "...");
here we have maxNumFragment=5 the the five best fragment
so I want to know and where I must modify in Solr to do that:
which class and how.
or in solrconfig.xml but i found this difficult may be I have to create my
Handler
I am waitin your suggestion how to deal with that.
