Hi,
I'm running MarkLogic Server Standard Edition 4.1-3 on Windows Server 2003.
I have just started exploring MarkLogic's search API. I'm using search:search
to perform full-text searches against a single document in our database. This
document contains content in both English (xml:lang="en") and German
(xml:lang="de"). The default language of our instance of MarkLogic Server is
English. My goal is to use search:search to perform searches against our
content and return results matching both the English or German content.
However, currently I am only receiving results matching against English
content, the default behaviour, and I cannot seem to alter this behaviour. I
have read Section 17 in MarkLogic Server Search Developer's Guide, but this
document only deals with multilingual support when constructing your own
queries via cts:search methods, whereas I am interested in using the more
out-of-the-box functionality provided by the search:search method.
Here is a simplified version of the code I'm using:
let $queryString := xdmp:get-request-field("queryString"),
$options := <options xmlns="http://marklogic.com/appservices/search";>
<constraint name="languages">
<annotation>
<term-option>lang=de</term-option>
</annotation>
</constraint>
<debug>{fn:true()}</debug>
<return-query>{fn:true()}</return-query>
<additional-query>{cts:document-query("/C/Documents and
Settings/Administrator/Desktop/diaries_schema/BreithauptDiaries.xml")}</additional-query>
<searchable-expression
xmlns:tei="http://www.tei-c.org/ns/1.0";>/tei:teiCorpus/tei:t...@xml:id="diary-ljb-1879-1881-1"]/tei:te...@type="diary"]/tei:body/tei:div</searchable-expression>
</options>,
$results := search:search($queryString, $options)
return $results
When I do a search with query text "pa" and look at the search:report returned
I get the following:
<search:report id="SEARCH-FLWOR">
(cts:search(/tei:teiCorpus/tei:t...@xml:id="diary-ljb-1879-1881-1"]/tei:te...@type="diary"]/tei:body/tei:div,
cts:and-query((cts:word-query("pa", ("lang=en"), 1),
cts:document-query("/C/Documents and
Settings/Administrator/Desktop/diaries_schema/BreithauptDiaries.xml")), ()),
("score-logtfidf"), 1))[1 to 10]
</search:report>
This SEARCH_FLWOR shows that search:search is constructing the underlying
cts:word-query with "lan=en", the server's default language, but I'm trying to
determine how to get search:search to construct underlying cts queries with
language determined by me (see the term-option constraint I've included in the
options argument). Ideally I would be able to set the language in the
underlying query constructors to be "lang=de" and equivalent queries
constructed with "lang=en" and then combine the results with cts:or-query.
If anyone has any thoughts or advice for me I'd greatly appreciate it. Please
let me know if it's possible to conduct multilingual searches using the
search:search method and the approach I've outlined here.
Thank you,
