Hi, I want to write my own query expander. It needs to obtain the AST (abstract syntax tree) of an already parsed query string, navigate to certain parts of it (words) and make logical phrases of those words by adding to the AST - where necessary.
This cannot be done to the string because the query logic cannot be semantically altered. (e.g. AND, OR, paren's etc) so it must be parsed first. How can this be done with SolrJ? thanks for any tips. Darren
