Hi there,

I will be committing a newer version of the tool soon (tomorrow or on 
Monday).

A very important thing is that PruneIndexTool uses a DIFFERENT syntax 
for queries than the Nutch web frontend. The syntax for the tool is 
Lucene QueryParser syntax - please see the javadoc comments for an example.

First of all, there must be no space between the field name, colon, and 
the query term. I assume it's just a transcription error, and not the 
real query...

Anyway, this query means that you want to match all documents, which 
contain "wordA wordB wordC" as an exact phrase in the content field. 
Probably not what you wanted... you probably wanted something like:

content:(wordA OR wordB OR wordC)

Am I right?
