[MarkLogic Dev General] question regarding search

[David Amusin]

Hi Srini,

You can include additional information from the result document (such  
as an article title) by using a custom snippet function.  You will  
need to include a transform-results node in your options XML with the  
attributes @apply, @ns, and @at.  For details, see section 2.2.6.2 of  
the Search Developer's Guide here: http://developer.marklogic.com/pubs/4.1/books/search-dev-guide.pdf

Here is an example of a custom snippet that will include the node from  
the result document with the local-name "name".  A node with QName  
"extra" will be included in the search:snippet node of every search  
result when search:search() is called.


custom.xqy:

xquery version "1.0-ml";
module namespace custom = "http://test.com/search";
import module namespace search = "http://marklogic.com/appservices/search 
"
     at "/MarkLogic/appservices/search/search.xqy";

declare function custom:my-snippet(
         $result as node(),
         $ctsquery as schema-element(cts:query),
         $options as element(search:transform-results)?
) as element(search:snippet)
{
<search:snippet>
{
(
         search:snippet($result, $ctsquery, $options)/*,
         <extra>{$result//*:name}</extra>
)
}
</search:snippet>
};



The call to search:search():

xquery version "1.0-ml";
import module namespace search = "http://marklogic.com/appservices/search 
" at "/MarkLogic/appservices/search/search.xqy";

search:search(
   "Gregory",
   <options xmlns="http://marklogic.com/appservices/search">
     <transform-results apply="my-snippet" ns="http://test.com/search"  
at="/custom.xqy" />
   </options>
)


Please let me know if the explanation or example are unclear at all.

Cheers,
David
