MarkLogic Search Suggest with Java API

I am trying to implement a search suggest for the app I am building. I tried following the guide found here.

I modified things a bit to work with my database. My options now look like this:

String options =
        <options xmlns="http://marklogic.com/appservices/search">
            <default-suggestion-source>
                <range type="xs:string" facet="true">" +
                    <element ns="http://marklogic.com/xdmp/dls" name="content"/>
                </range>
            </default-suggestion-source>
        </options>;

The name "content" is the name of the XML element I want to search, and the namespace I wasn't sure about, so I just copied the namespace that was in the default range indexes already in my database.

My Index looks like this: range element index

My Java code is as follows:

StringHandle handle = new StringHandle(options);
QueryManager queryManager = client.newQueryManager();
QueryOptionsManager optMgr = client.newServerConfigManager().newQueryOptionsManager();
optMgr.writeOptions("opt-suggest", handle);

SuggestDefinition suggestionDef = queryManager.newSuggestDefinition();
suggestionDef.setLimit(10);
suggestionDef.setStringCriteria(text);
suggestionDef.setOptionsName("opt-suggest");
String[] suggestions = queryManager.suggest(suggestionDef);

The line setting the options name to the suggestion def I added as it was not in the tutorial. The search returns an empty set every time. Is it because of my namespace? Or am I missing something? FWIW I have tried running it with the namespace shown, and with a blank namespace.

Edit: Sample document:

<Article doctype="article>
    <title>Some Name here</title>
    <content>
        <content type="paragraph">
            <value>Some text</value>
        </content>
        <content type="paragraph">
            <value>More text</value>
        </content>
    </content>
</Article
Solution

  • It works! Sam Mefford's comment about running in the console made me realize it would in fact return results, just not for my search string. I threw some wildcards around the search text and it now works; after adjusting my index and options to search the proper XML element, and leaving the namespace blank.
