Redmine

Currently, the search engine does not support multiple multi-word phrases.

For example, we cannot search objects that contain two phrases "closed issue" and "closed version". If you give a search string "closed issue" "closed version", the search engine search for objects containing three strings "closed issue", "closed", and "version". This is due to the behavior of Redmine::Search::Tokenizer#tokens.

Redmine::Search::Tokenizer.new(%q|"closed issue" "closed version"|).tokens
=> ["closed issue", "closed", "version"]

If the Tokenizer returns two tokens, "closed issue" and "closed version" for the same input, it will be possible to search for multiple multi-word phrases.
