Thanks,
Here is a ruby translation for those that want it:
solr_query = ""
doi_part.each_char do |c|
if (c == '\\' || c == '+' || c == '-' || c == '!' || c == '(' || c
== ')' || c == ':' || c == '^' || c == '[' || c == ']' || c == '\"' || c ==
'{' || c == '}' || c == '~' || c == '*' || c == '?' || c == '|' || c == ';')
solr_query += '\\'
solr_query += "#{c}"
elsif (c == '&')
solr_query += "%26"
else
solr_query += "#{c}"
end
end
solr_query
It still seems to get confused by & characters and turning them into %26
does not work from the solr-ruby connection. ..but it works for most of the
DOI's that I have tried so still a big improvement - thanks.
