Subject [jira] Commented: (JSPWIKI-489) Searching with wildcards
Date Tue, 03 Feb 2009 14:33:59 GMT

    [ https://issues.apache.org/jira/browse/JSPWIKI-489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12669969#action_12669969

Siegfried Goeschl commented on JSPWIKI-489:
-------------------------------------------

You cannot use a * or ? symbol as the first character of a search (see http://lucene.apache.org/java/2_3_2/queryparsersyntax.html)
because you have a wildcard query where the wildcard is at the beginning of the search string
- this causes performance problems. Usually you get a Lucene exception when doing that - but
an implementation can choose to overwrite this method to silently ignore that exception

> We have noticed that searching for two letter words is not possible, e.g. looking for
"AS IS". Sometimes it could be nice if this would be possible, but this is not the point of
this issue.
> A search for "%%sub" (or for "%%sup") results in all pages where these formatting instructions
are used.
> A search for "su*" results in lots of pages where words starting with "su" appear.
> A search for "%%su*" is however unsuccessful, no pages are found, although there are
indeed pages with %%sup en %%sub.
