Re: [Sedna-discussion] Little feature request.

Hi,

You can use fthighlight function for this, it returns a string
containing XML with '<' replaced by &#xE801;, '>' replaced by
&#xE802;, and some " replaced by &#xE803;, with added <hit> tags
around matched words.
Here's an example of a query that returns matched documents in XML:

declare option se:character-map "&#xE801;=<";
declare option se:character-map "&#xE802;=>";
declare option se:character-map "&#xE803;=&amp;quot;";
let $q := "query"
for $r in ftindex-scan("fti",$q)
return
 fthighlight($r, $q, "as_index=fti")

If you need to get matched words, you'll need to use something like
fn:tokenize & fn:replace (using functx:get-matches would be easier,
but AFAIR it's not available in Sedna)

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
