Dear Naoki-san, The Webhelp content indexer is indeed based on the Lucene engine just like the Kuromoji morphological analyzer, so delegating the task of indexing any Japanese content at build time (when the Webhelp pages are created by the Oxygen Webhelp transformation) to the Kuromoji analyzer is doable. However the Webhelp search is performed at runtime on the client side, with JavaScript code running on the machine where the Webhelp search is executed in the browser, not on the server side, where the Webhelp pages are stored. The difficulty in integrating an analyzer that deals with a specific language sentence morphology like the Kuromoji analyzer comes from the lack of an equivalent JavaScript analyzer that is able to split the search string entered by the user into the morphological components recognized by the Lucene-based morphological analyzer that built the index database at build time. I did a Google search but I could not identify a client side JavaScript solution for a Japanese morphological analyzer. If you can suggest such a solution we would surely consider it as a future improvement for the Webhelp search. Kind regards, Sorin Naoki Hirai wrote:
Hi,
I like Oxygen WebHelp very much and recommend it to Japanese users. The WebHelp is sophisticated online manual solution, but one issue has still remained for Japanese users. That is a Japanese search. For Japanese it's difficult to extract words from sentences. Because the words are not separated by spaces. Therefore, in general, a morphological analyzer is used to extract the words from the sentences. Recently, an open source Japanese morphological analyzer which is called "Kuromoji" has become popular. The Apache Solr has introduced Kuromoji as the morphological analyzer.
So, my feature request is that Oxygen WebHelp plug-in will incorporate Kuromoji as the morphological analyzer. And add a parameter which selects a stemmer for generating a WebHelp output. I can help the development and the evaluation.
Please have a thought.
Best regards,
Naoki
