【问题描述】:
我在尝试指定搜索参数以仅搜索我的文件中的特定 xml 元素时遇到问题。这是我用来搜索的文件:
<file>
<title>red</title>
<info>
<section>blurbs</section>
<section>words</section>
</info>
<info>
<section>first</section>
<section>this</section>
</info>
<info>
<section>blue</section>
<section>green</section>
</info>
<info>
<section>red</section>
<section>yellow</section>
</info>
</file>
我使用的搜索:搜索查询是:
xquery version "1.0-ml";
import module namespace search = "http://marklogic.com/appservices/search"
at "/MarkLogic/appservices/search/search.xqy";
let $options :=
<options xmlns="http://marklogic.com/appservices/search">
<additional-query>
<cts:document-query depth="infinity" xmlns:cts="http://marklogic.com/cts">
<cts:uri>/test_data/test_search.xml</cts:uri>
</cts:document-query>
</additional-query>
<extract-document-data selected="include">
<extract-path>/file/info</extract-path>
</extract-document-data>
<constraint>
<word>
<element name="info"/>
</word>
</constraint>
<search-option>filtered</search-option>
</options>
let $results := search:search("red", $options)
$results 变量包含:
<search:response snippet-format="snippet" total="1" start="1" page-length="10" selected="include" xmlns:search="http://marklogic.com/appservices/search">
<search:result index="1" uri="/test_data/test_search.xml" path="fn:doc("/test_data/test_search.xml")" score="8448" confidence="0.4065818" fitness="0.8925228">
<search:snippet>
<search:match path="fn:doc("/test_data/test_search.xml")/file">
<search:highlight>red
</search:highlight>
</search:match>
<search:match path="fn:doc("/test_data/test_search.xml")/file/info[4]">
<search:highlight>red
</search:highlight>
</search:match>
</search:snippet>
<search:extracted kind="element">
<info>
<section>blurbs
</section>
<section>words
</section>
</info>
<info>
<section>first
</section>
<section>this
</section>
</info>
<info>
<section>blue
</section>
<section>green
</section>
</info>
<info>
<section>red
</section>
<section>yellow
</section>
</info>
</search:extracted>
</search:result>
<search:qtext>red
</search:qtext>
<search:metrics>
<search:query-resolution-time>PT0.00166S
</search:query-resolution-time>
<search:snippet-resolution-time>PT0.000992S
</search:snippet-resolution-time>
<search:extract-resolution-time>PT0.00049S
</search:extract-resolution-time>
<search:total-time>PT0.003748S
</search:total-time>
</search:metrics>
</search:response>
如您所见,标题和信息上出现了红色,但我只想在 xml 信息元素上进行搜索。我在这里做错了什么?
编辑:我对约束搜索 IE search:search("title:red") 有一点了解,但是当约束是多个单词时会发生什么?
