[MarkLogic Dev General] Help with xQuery Syntax

Thu Mar 4 08:01:16 PST 2010

Chris,

Depending on the type of query you want to perform on those structures, it sounds more like a <word>, <value> or <range> constraint.  One tutorial you might want to look at, in addition to those Mike lists below, is:

http://developer.marklogic.com/howto/tutorials/2009-07-search-api-walkthrough.xqy

That has some information on the different constraint types and how they relate to the searches you want to perform.

Thanks, Michael.  After reading about the search API, it does seem like a simpler approach.  So in order to perform a google-like search within any Sect1 or Sect2 in the structure below, I would use a collection constraint -- correct?

Thanks again for your help.

Chris,

Why not use the higher-level search:search() API? The function reference page is http://developer.marklogic.com/pubs/4.1/apidocs/SearchAPI.html#search:search

The Search Developer's Guide (http://developer.marklogic.com/pubs/4.1/books/search-dev-guide.pdf) has more about the high-level search API.

If you need to use the lower-level cts:search() API for some reason, start with http://developer.marklogic.com/howto/tutorials/ and the "Paginated Search for Web Applications" tutorial.

Hello,

I'm new to MarkLogic and am having trouble getting a search query to work properly.  Specifically, I'm attempting to build a simple query of a DocBook style document.  The structure of the document is as follows:

<article>
     <sect1>
     <title>The first title</sect1>
     <para>a paragraph of text</para>
<sect2>
<title>The first title</sect1>
  <para>a paragraph of text</para>
 </sect2>
    </sect1>
</article>

My goal is to build a simple search tool that will search through all<sect1>  and<sect2>  elements and find any paragraph containing the search term.  I'd like to return:

<a href="somelink.xqy">Section Title</a>
<p>Paragraph text with<span class="highlight">highlighted search term</span>  in it.</p>

The problem is that when I loop through the paragraphs containing the search term, I return every sect1 or sect2 title, regardless of whether that title contains para elements with the search term.

Here's what I have so far:

=======================================
xquery version "1.0-ml";

xdmp:set-response-content-type("text/html"),
<html>
<body>
<head>
<link rel="stylesheet" type="text/css" href="affect.css" />
</head>
<div class="container">
<div class="topNav">
<form method="GET" action="searchtest3.xqy" id="searchForm">
 <input type="hidden" name="start" id="start" value="1"/>
<input type="text" name="search" size="43" maxlength="256" value=""/>
<input type="submit" name="button" value="search"/>
</form>
</div>
{let $searchTerm := xdmp:get-request-field("search")
let $query := cts:query(<cts:word-query xmlns:cts="http://marklogic.com/cts"><cts:text>{$searchTerm}</cts:text></cts:word-query>)

for $newresults in (//sect1|//sect2)
where cts:contains(($newresults//para), $query)
return
<div>
<a href="www.google.com<http://www.google.com><http://www.google.com>" class="searchResult">{$newresults/title/text()}</a>

{
for $para in $newresults/para
where cts:contains($para, $query)
return
<p>{cts:highlight($para[1],$query,<span class="highlight">{$cts:text}</span>)}</p>
}
</div>}
</div>
</body>
</html>
=======================================

Thanks for your help!

Chris
