Thanks Shawn! That makes sense now. I appreciate the response.

Re: solr 4.3 solrj generating search terms that return no results

[dboychuck]

I'm having the same issue with solrJ 4.5.1

If I use the escapeQueryChars() function on a string like a b c it is
escaping it to a\+b\+c which returns 0 results using edismax query parser.
However a b c returns results.

A space is a special character to the Solr query parser.  It is a term
delimiter.  This means that if you are escaping all special characters,
you have to escape the space.

If you do not want the *entire* string treated as a single term for the
query parser, then you cannot use escapeQueryChars.  You'll need to
write your own code that is aware of the specific special characters
that you want to escape.

Thanks,
Shawn

If your query is already available in pieces rather than just a string
that the user types in, you could do something like the following.  I
don't imagine that this level of object detail would be available, though:

String escTerm1 = ClientUtils.escapeQueryChars(term1);
String escTerm2 = ClientUtils.escapeQueryChars(term2);
String escTerm3 = ClientUtils.escapeQueryChars(term3);
String queryStr = escTerm1 +   + escTerm2 +   + escTerm3;
solrQuery.setQuery(queryStr);

solr 4.3 solrj generating search terms that return no results

[dboychuck]

I'm having trouble with solrj generating a query like q=kohler%5C+k for the
search term 'Kohler k'

I am using Solr 4.3 in cloud mode. When I remove the %5C everything is fine.
I'm not sure why the %5C is being added when I call
solrQuery.setQuery('Kohler k');

Any help is appreciated.

%5C is a backslash.  In order for a space to be a literal part of a
query string and not a tokenization point, it must be escaped, and the
character for doing that is a backslash.

I would not have expected this to be added, though.  I am in the process
of building a test app to try this.  Can you use http://apaste.info to
share more of your solrj code?  I should also be on IRC momentarily.

Thanks,
Shawn

solrQuery.setQuery(ClientUtils.escapeQueryChars(keyword));

It looks like using the solrj ClientUtils.escapeQueryChars function is
escaping any spaces with %5C+ which returns 0 results at search time.
