Solr's dismax parser can generate queries that do most of this... it's

Simplest example:

I have documents containing multiple words in the the field "word"
for example, one of the documents contain in the field "word" the following:

When searching for single words (i.e. homewoners ) I get hits.
However, searching for the exact phrase "homeowners work" gives me no hits

take those two, and make two tokens as keyword analyzer would do.
This way one can search bidirectionally edges of a graph with one

As I understand it, there really is no "space indicator". I think of it
as replacing the stop word with a space, which is then discarded.
so, you're indexing 'you find answer', and both your searches are
looking for 'you find answer', the stop words are just gone as though
they never were. So bo
I found some discussions of this question from back in 2003, but that was
many updates ago.
I have built an index using the standard stop analyser which uses the
standard list of stop words. "will" and :the" are stop words.
As I understand analyzers and phrase queries, when I search for

Assuming it is, I subclassed the QueryParser to handle phrase prefixes,
replacing getFieldQuery by a version that calls the super, and if the
result is a phrase query and the text contains an asterisk tries to
create a MultiPhraseQuery. This seems to work ok, returning a
