Question

I use Solrnet to develop a search engine. In my application, I have a field called file_contents which I use for highlighting. Am able to get the highlights without a problem. Now I need to format it. For example, if the keyword occurs multiple times in the field, I have to display it lime what google does. May be like this.

GSMArena.com: Toshiba GSM cellphones. … Toshiba phones. Toshiba. Filters. Available · Coming soon · Smartphone · Touchscreen · Camera · Bluetooth · Wi-Fi …

Multiple snippets here are separated by “…”. I need to achieve something like this. Am able to get multiple snippets. But how do I deal with the separating?

Regards

Without much to go on in the question about what format the snippets data is in, assuming it’s in an array called YourArrayOfSnippets, you’d do:

string joined_snippets = string.Join(" ... ", YourArrayOfSnippets);

And then use joined_snippets however you see fit.

In fact, SolrNet has a wiki page on highlighting with an example of how you might handle highlighting results, and even shows the use of Join. Basically:

var results = solr.Query(new SolrQueryByField("features", "noise"), new QueryOptions {
    Highlight = new HighlightingParameters {
        Fields = new[] {"features"},
    }
});
foreach (var h in results.Highlights[results[0].Id]) {
    Console.WriteLine("{0}: {1}", h.Key, string.Join(", ", h.Value.ToArray()));
}
