It works, thanks. Just implemented the code...:):):) Could you explain what {!field f=yourStringField}Cameras Photos does.

Filter query with special character using SolrJ client
Hello, I am trying to get filter querying to work on search. When the filter query contains no special character or is a single word the filter query parameter returns the result as expected. However when I run filter query where special characters are present no results are results. e.g Cameras Photos, I removed the character as well (Cameras and Photos) and still no results are returned. However for a string like Electronics the results are returned as expected. I am using the string field to store and index the field that I want to filter and SolrJ as the client. From the documentation I read solrJ automatically escapes special characters. Any help regarding this is much appreciated. Regards, Indika

Can you try this: SolrQuery.addFilterQuery(yourStringField:Cameras\\ Photos)
Re: Filter query with special character using SolrJ client
Thanks for the info. I'll have a try and see how the results are. Since the names of the string fields are not predefined I might have to find a method to do this automatically. I'll try a few more workarounds and see what the results turn out to be.
