[MarkLogic Dev General] Limiting cts-search to fields

[Danny Sokolsky]

Hi Nicole,
 
I can think of two ways you might accomplish this.
 
1) You can make the first parameter of your cts:search only cover the
things you want to search with an or.  Something like:
 
//METS:dmdSec/METS:mdWrap/METS:xmlData/(dc:title | dc:creator | dc:date
| dc:type | etc | etc)
 
making sure to leave the element you want to exclude off the list.  The
problem here is that it would return the inside elements that match the
search, and you wanted the METS:dmdSec element.  You can achieve that by
sticking an XPath on the end of your search, something like this:
 
declare namespace METS="foo"
declare namespace dc="bar"
 
let $query := cts:word-query("Article")
return
cts:search(doc("test.xml")//METS:dmdSec/METS:mdWrap/METS:xmlData/(dc:tit
le | dc:creator | dc:date | dc:type), $query)/ancestor::METS:dmdSec
 
It seems like you might get some duplicates with this method, too (for
example, if you had a match in both a title and creator elements having
the same METS:dmdSec ancestor), and you would have to deal with that.
 
2) Alternately, you can use the 3.2 Fields feature and create a field
that excludes the dc:source element.  Then your cts:query would use
cts:field-word-query instead of what your mlps:get-cts-query generates
(presumably you would need to modify that function to generate the
cts:field-word-query constructor).
 
There may be other ways, but I can't think of them right now.

	I'm looking to limit what fields our search looks at when
pulling results.

	 

	We have this function:

	 

	define function quick-search ($params as node()) as node()* {
	
	let $query := mlps:get-cts-query(fn:data($params/terms))
	let $raw-results := cts:search(//METS:dmdSec,$query)
	let $results := build-results($params, $raw-results, $query)
	return
	  (
	  if ($results/result) then
	    (v:display-results($params, $results))
	  else
	    v:display-no-results($params)
	  )
	
	} 

	 

	And here is a snippet of the XML

	 

	<METS:dmdSec ID="dmd002">
	        <METS:mdWrap MIMETYPE="text/xml" MDTYPE="DC"
LABEL="Dublin Core Metadata">
	            <METS:xmlData>
	                <dc:title>Front Cover</dc:title>
	                <dc:creator/>
	                <dc:date>1984</dc:date>
	                <dc:type>Article</dc:type>
	                <dc:language>English</dc:language>
	                <dc:source>Bibliographie Karl Barth Band 1:
Ver&#xF6;ffentlichungen von Karl Barth (1984)</dc:source>
	                <dc:coverage>fa-fb</dc:coverage>
	                <dc:description/>
	                <dc:subject/>
	            </METS:xmlData>
	        </METS:mdWrap>
	    </METS:dmdSec> 

	 

	What I want is to have the search search everything but the
source field.  I'm up for any suggestions!

	 

	Thanks,
