search for: queryparserrules

Hi, I have some questions about searching with Ferret. I have a user index with first_name, last_name and full_name (which is just first plus last with a space). Here are a couple of questions: 1) If I store the fields tokenized, it appears as though queries are case-insensitive. However, for untokenized, the query is case-sensitive. How can I make the untokenized searches case-insensitive?

I need to be able to search for certain symbol characters. For example, I want the search for c++ to work. I try enclosing it in quotes, but it seems to treat C and the pluses as two separate characters to look for. Search for ++ alone seems to find documents that don''t have any pluses in them. Why would that happen? Thanks, Carl
