It's quite common to build a Query by API rather than through
QueryParser, exactly as you mentioned. Manually run through an
Analyzer's output to build whatever type of query clauses desired.

all the text parsed, I just want to run the name field through an

zip and city. I'm wanting to do ~2,500 specific searches on an
index with between 26m documents. I know ahead of time what most of
my fields will be. I thought I could save some time by not having to
separate my fields, making a giant string, then having QueryParser
split the string back into terms to search.

You can combine queries . (such as your custom "TermQuery" + the
result of a
"QueryParser.Parse")

I can convert this text into a Query using just TermQuery and
BooleanQuery:
name:"ACME Produce" AND city:Anytown AND zip:90210
If I create the Query object on my own will I loose all the
benefits from
things like StandardAnalyzer? Is there a way I can submit an object
graph
to QueryParser so I can get the benefits of its analyzer without
making it
parse the raw string? My input is coming from well defined areas;
its not
free form where the user can enter anything they want.
Can I use a StandardAnalyzer myself then take its output and create
the
appropriate Query objects then join all of them into a BooleanQuery?
I'm using /tags/Lucene.Net_2_4_0.
