Solr Query not parsing forward slash

Question

Is the forward slash \"/\" a reserved character in solr field names?

I\'m having trouble writing a solr sort query which will parse for fields containing a forward s

Answer 1

In my case I needed to search for forward slash / with wild card *, e.g.:

+(*/*)
+(*2016/17*)

I Tried to escape it like so:

+(*2016\/*)
+(*2016\/17*)

but that didn't work also.

the solution was to wrap the text with double quote " like do:

+("*\/*")
+("*/*")

+("*2016\/17*")
+("*2016/17*")

both returned the same result with and without escaping the forward slash

Answer 2

From the solr wiki at https://wiki.apache.org/solr/SolrQuerySyntax :

Solr 4.0 added regular expression support, which means that '/' is now a special character and must be escaped if searching for literal forward slash.

Answer 3

I just came across the same problem, and after some experimentation found that if you have a forward-slash in the field name, you must escape it with a backslash in the Solr query (but note that you do not have to do this in the field list parameter, so a search looking for /my/field/name containing my_value is entered in the "q" field as:

\/my\/field\/name:my_value

I haven't tried the sort field, but try this and let us know :)

This is on Solr 4.0.0 alpha.
