Subject [jira] Commented: (JSPWIKI-498) Performance Issues with Lucene Index
Date Sat, 14 Feb 2009 14:07:59 GMT


Harry Metske commented on JSPWIKI-498:

a bit more room for improvement still:

* name your patch files properly, using the .patch suffix (makes handling easier with most
editors, and gives automatic correct syntax highlighting)
* some parameter names do not adhere to the standards
* method docs are incomplete
* please use the JSPWiki code formatting (
* an unnecessary import of StopWatch in Search.jsp
* there is still a findPages(String,int,int) left in WikiEngine
* is it possible to include one or more JUnit tests (to reduce the chance that we break your
work in the future) ?

Another suggestion: Have you tried using the Eclipse CheckStyle plugin ?

>          Issue Type: Bug
>          Components: Default template
>    Affects Versions: 2.8.1
>         Environment: Win 2003 on XEN-Server, 3 GB RAM, 4 x Intel Xeon 2Ghz

> Our Wiki-Luceneindex has swollen to 33 MB and if someone searches words like "find" he
gets about 500 results. Only problem is, it takes about 30 seconds to complete the search.
> I have looked a bit into the problem and there is something strange to me. JSPWiki searches
twice every query. 
> Once in search.jsp and afterwards in AjaxSearch.jsp.
> The filteredList from search.jsp is written to the pagecontext but this information is
never read within the AjaxSearch.jsp. Thus AjaxSearch.jsp makes a second search.
