How to Increase/Configure Snippet size of a highlight?

Question

I want to know that how we can configure Snippet Size(number of words/Characters) in highlighting? Currently i m facing a problem, sometimes solr Gives me snippet exactly the matched word. like let say I query solr as "Contents:risk" using solrnet it gives me exactly "risk" in highlighting snippets no more characters or words i do the same with Solr admin and it gives the same result too.

Answer 1

I'm not quite familiar with highlighting features but I believe this is done with the hl.fragsize parameter.

Answer 2

Mauricio already answered and this is a little bit of an old thread, but just to add the solution using SolrNet it would be:

• Create a new Highlighting parameters object.

• Set fragsize

• Other parameters are possible

• Highlighting documentation can be found here: Highlighting.md

Here is a sample code:

 private HighlightingParameters SetHighLightSnippetParameters()
        {
            return new HighlightingParameters
            {
                Fragsize = SearchConstants.SnippetSize
            };
        }
