search – MarkLogic对变音不敏感的片段

2023年12月14日 266次阅读

现在,我正在使用此代码生成代码段,基于我从MarkLogic搜索获得的
JSON文档.

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

declare function searchlib:get-snippet($docc,$words) {
  let $doc:= json:transform-from-json($docc)
  let $squery := search:parse($words)
  let $result := <result>{search:snippet($doc,$squery,
  <transform-results apply="snippet" xmlns="http://marklogic.com/appservices/search">
          <max-snippet-chars>255</max-snippet-chars>

      </transform-results>)}</result>

  return $result//search:match
};

执行搜索我正在使用：

cts.jsonPropertyValueQuery(fieldname, values, 
                                             ['case-insensitive', 'diacritic-insensitive'])

因此搜索工作变量不敏感并产生良好的结果,但在搜索：片段我无法传递变音不敏感选项,如cts.jsonPropertyValueQuery.

在documentation我可以在描述中看到这一点

Options to define the search grammar and control the search. See description for $options for the function search:search. Note that you cannot specify the apply attribute on the transform-results option with search:snippet; to use a different snippetting function, use search:search or search:resolve instead.

但在这里它是：

search:snippet(
   $result as node(),
   $cts-query as schema-element(cts:query),
   [$options as element(search:transform-results)?]
) as element(search:snippet)

那么这是否意味着我无法通过其他选项进行搜索：片段？或者可以选择这样做吗？

我正在使用chávez测试它并且它正在产生结果,但是仅对包含完全匹配的文档正确生成片段,这意味着该文档

对查韦斯不会高兴

最佳答案 问题在于没有传递搜索选项：片段,而是搜索：解析

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

declare function searchlib:get-snippet($docc,$words) {
  let $doc:= json:transform-from-json($docc)
  let $squery := search:parse($words,
<options xmlns="http://marklogic.com/appservices/search">
<term>
<term-option>case-insensitive</term-option>
<term-option>diacritic-insensitive</term-option>
</term>
</options>, "cts:query")

  let $result := <result>{search:snippet($doc,$squery,
  <transform-results apply="snippet" xmlns="http://marklogic.com/appservices/search">
          <max-snippet-chars>255</max-snippet-chars>

      </transform-results>)}</result>

  return $result//search:match
};

通过

<term-option>diacritic-insensitive</term-option>

搜索：解析使它工作.

以下是MarkLogic的解释：

The search:snippet() function allows you to extract matching text and
returns the matches wrapped in a containing node, with highlights
tagged. However, to allow the search:snippet to extract the correct
text, the cts:query() that is passed to the snippet should match the
sequence of values. For search:snippet, cts:query is typically a
result of a call to search:parse. The search:parse() function parses
query text according to given options and returns the appropriate
cts:query XML.
