BooleanQuery constructor

[Mike Anderson <mi...@MIT.EDU>]

I have a string that represents a boolean query (because I passed it  
in as a URL parameter), is it possible to instantiate a BooleanQuery  
object that represents this query?

I think what I am looking for is something like a BooleanQuery  
constructor that takes in a string, but this doesn't exist. The other  
option would be to create a new empty Boolean Query and then  
deconstruct the string and populate my new BQ, but i'm not sure how to  
deconstruct the string in this way.

Any help would be appreciated.

A Query object is independent of the string representation. Look at Lucene's
org.apache.lucene.queryParser.QueryParser#parse(String)
