Query question

Hi all,

	I have a field called "echelon" that are assigned to certain files.  Is
there a query I can write that will give me all files that have this field?

	I have tried stuff like echelon:.+*, echelon:*, etc... some give a query
parser exception while others return nothing.

Let me know,

Rob

Aha.  You can't do it with a query, unless you add a fixed-value field
to all documents added to your index.
e.g.
field:X

Then you can get all documents by searching for +field:X

Otis,

	Are you referring to this:

		How do I retrieve all the values of a particular field that exists within
an index, across all documents?

I need a query to do it, the only way clients access the index is via
queries so they cannot write the code in the faq above.

Thanks,

Rob

Go to Lucene FAQ at jGuru.com and search for the word 'all'.
