Hi,

I generate searches similar to these for the simple/advanced search in the UI and I don't have any problems.

E.g. if you have an item called "release.gif"
then a search:


@\{http\://www.alfresco.org/model/content/1.0\}name:release*
‍‍‍

will find it ok, and also a search:


@\{http\://www.alfresco.org/model/content/1.0\}name:*elease*
‍‍‍

will also find it ok.

I think the problem in your searches in the use of quotes around the terms when searching against an attribute. E.g. you search for:


TEXT:"*ani*"
( @\{http\://www.alfresco.org/model/content/1.0\}name:'*ani*") 
‍‍‍‍

whereas if you change it to this:


TEXT:*ani*
( @\{http\://www.alfresco.org/model/content/1.0\}name:*ani*)
‍‍‍‍

You should get the results you are looking for.

Hope this helps,

Kevin

Hi

To be explicit….

Using "" in a search like ns\:woof:"*and*"
Does a lucene phrase search - * is not treated as a wild card in phrase searches - it will split this into tokens. The default result is do an exact match for the token "*and*" (not tokens that match this pattern) which probably does not exist

Wildcards are only available outside phrase searches, e.g.

ns\:woof:*and*

In phrase searches, the text is tokenised and '_' is used as a token separator. By default we use the StandardAnalyser for text.

Can you send me the null pointer exception and I will have a look at this??

Regards

Andy
