Re: Best Solr escaping?

[Chris Hostetter <ho...@fucit.org>]

a) It depends entirely on what QueryParser you are using.

If your input is "from a human" i would suggest using dismax or edismax 
and not escaping anything - unless you get some type of error, and then 
maybe give the user a "there was a problem with your query, would you like 
to try ____" where you suggest a new query with all meta-characters striped out.

b) URL escaping is really a completley independent issue...

: * Should we use + or %20 ­ and what cases make sense:
: > * "Dr. Phil Smith" or "Dr.+Phil+Smith" or "Dr.%20Phil%20Smith" - also what is

...solr doesn't know of car wether you use "+" or "%20" when building up a 
URL.  by the time Solr sees your input, the servlet container has already 
url-decoded the query params.

in general: if you are even *thinking* about how params are getting URL 
encoded, you are probably doing something wrong.  writing custom code to 
construct Solr query strings is one thing, writting custom code to 
construct/escape values in URLs is something else -- i don't know what 
client langauge you are using, but i garuntee you it has an HTTp/CGI API 
that completely eliminates any need for you to even think about such 
issues.
