Hi Madhu,
You could use IndexSearcher.explain(..) to explain the result and get the

understanding the boost and score as calculated by lucene for your app.

Relevance or an apt method about boost values, can again be figured out

general practice.
Hope this helps you figuring out a reasonable solution and boost values.

So Update basically is nothing but delete and add (a fresh doc). You could

adding the new document? That is the general approach for such cases and it

The below would work and get you all the docs in the index as the result

As far as relational nature is concerned, I'd say lucene's model is pretty
different from what you're taking it to be. Lucene documents are just a

The

to getting indexed. The way the processing would happen depends on your
analyzer (which here is StopAnalyzer). So point 1. If you analyze a field
with value *'My name is anshum' *it would get broken down into tokens, e.g.
[my] [name] [is] [anshum] where ea
Hi,
How about indexing a dummy token for empty docs? that way you may pick up
all docs that are actually null/empty by querying for the dummy token.
Make sure that the dummy token is never a part of any actual document (token
stream).
Perhaps this should work!

There ofcourse are implementation schemes that you might want to try so as
to split the index and query them using the appropriate searcher, but this

Hi Mike,
Not really through queries, but you may do this by writing a custom
collector. You'd need some supporting data structure to mark/hash the
occurrence of a domain in your result set.

Index flipped terms (using an appropriate analyzer) i.e. cat is also indexed
as tac. You may then query on ta* instead of at*.
Does that solve your issues/concern?
