Subject Re: Error occurs when using the query_tool script of the file manager for a new product type
Date Sat, 01 Nov 2014 17:34:30 GMT
Thanks Angela,

Yes you are using the wrong syntax for Lucene. The syntax should be:

┬│Fieldname:FieldValue┬▓

Please see the syntax here:

http://lucene.apache.org/core/2_9_4/queryparsersyntax.html


Cheers,
Chris
