Re: DLL load failed: The specified module could not be found. from
jcc import _jcc
Hi Thomas, Thanks for the follow up. I have resolved this by instead using
SOLR, which provides a REST interface and scalability for my web
application. There also are hosted solutions which offer SOLR which make
deploying the solution easier. It did require me to go back and refactor
my code :-( but at least is working well.
Thanks.

AW: DLL load failed: The specified module could not be found. from jcc import _jcc
Posted by Thomas Koch <ko...@orbiteam.de>.
Hi Carlos,
thanks for your feedback - though I'd call it rather a workaround than a
solution of the original problem ,-)
Anyway, SOLR is based on Lucene and you can access it from Python as well ,
so this should be fine if it solves your initial problem.
There's also an approach to wrap SOLR in Python, but I currently can't
remember the project name nor find it...
regards
Thomas
