Re: ANYONE? Lucene problem in Slide ,TooManyClauses , DASL search stopped working!

What is your query? Most probably it is caused by the query expression. I faced this problem when i use this type of query:-

hello*******
***hel***
5****
***9
etc.
This is something related to bad wildcard query.

Hi Eirikur!

You need to inspect the query that is being passed over to Lucene to
find out what is wrong. This either works by debugging the code and
inspecting the variable values (AbstractLuceneExpression, line 224
does the Lucene call). Or you inspect the log as the query is written
to the log in line 208). You need debug level enabled for that class,
though. Use log4j logger to set fine grained logging settings.

Maybe you want to post the expression to the list, if you still have no clue.
